Caterpillar 3306B

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar 3306B is an inline six-cylinder, four-stroke marine diesel, built as a direct-injection turbocharged (BT) or turbocharged-aftercooled (BTA/DITA) engine. Displacement runs about 10.5 L (638 cu in) from a 121 mm x 152 mm (4.75 in x 6.00 in) bore and stroke. Cat packaged it for propulsion, ship-service auxiliary, and generator-set duty, each offered heat-exchanger (raw-water) cooled or keel-cooled, with marine power ratings spanning roughly 163-268 kW (218-360 mhp) at 2,000-2,200 rpm depending on rating class and configuration. Dry weight runs from about 1,030 kg (2,265 lb) up to roughly 1,120 kg (2,469 lb) depending on the package. Cat built the 3306B mainly from the mid-1980s into the mid-1990s, following the earlier naturally aspirated/precombustion-chamber 3306 (itself a successor to the D330/D333 industrial and marine engine line), and it gave way to the 3306C and later electronic C-series marine engines.

The step from 3306 to 3306B added direct injection and turbocharging, with aftercooling on DITA-rated versions, lifting output and fuel efficiency over the earlier precombustion-chamber design. Within the 3306B line, Cat split ratings across BT (turbocharged only) and BTA (turbocharged-aftercooled) versions, offered with raw-water or keel/jacket-water cooling packages to suit different hulls and operating environments. The 3306B shows up widely in tugs, trawlers, ferries, pump boats, and fireboats built through the 1980s and 1990s, and that installed base keeps demand for rebuilt long blocks, exchange components, and wear parts active today. Its fully mechanical fuel system and governor, with no electronic control module, make it straightforward to diagnose and service in the field, which is part of why operators still keep these engines running well past their original design life.

3306B fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase (lube oil system, incl. filter)27.4 L (7.2 US gal) refill on marine propulsion ratings (A through E, 160-265 bkW); 38.8 L (10.25 US gal) refill on marine generator-set ratings (145-190 ekW, both radiator-cooled and heat-exchanger/keel-cooled). Capacity varies by configuration -- generator-set sumps hold roughly 40% more than propulsion sumps.Caterpillar DEO (Diesel Engine Oil), SAE 10W-30 or SAE 15W-40. Oil change interval is 250 hours. Pick the grade for the climate: 10W-30 for colder ambient/easier cold starts, 15W-40 for warmer/hot ambient service. Use an API CF-4 or better heavy-duty diesel oil if Cat DEO is unavailable.
Cooling system (engine jacket water)Engine-only capacity varies by cooling arrangement: 18.2 L (4.8 US gal) on propulsion engines with the jacket-water/transmission-oil-cooler package, or 15.9 L (4.2 US gal) engine-side on propulsion engines with the sea-water-pump/heat-exchanger package; 15.9 L (4.2 US gal) engine-only on heat-exchanger or keel-cooled generator sets; 25.0 L (6.6 US gal) on radiator-cooled generator sets. External heat-exchanger, keel-cooler, or raw-water piping adds more and is not counted here -- treat as varies by installation.Caterpillar heavy-duty antifreeze/coolant with corrosion inhibitor (supplemental coolant additive) in the closed jacket-water circuit, mixed per the coolant specifications chapter. Raw seawater or keel water passes through the heat exchanger or aftercooler circuit separately and is not a fill-and-recommend fluid; maintain SCA concentration per the coolant service schedule.
Fuel tankNot specified in the engine documentation -- the engine ships without an integral fuel tank. Day-tank or vessel fuel tank sizing is set by the boat builder/installer, not the engine package.No. 2-D diesel fuel meeting Caterpillar's fuel specification; use a low-sulfur diesel where required by the installation.
Marine reverse-reduction gear / transmission compartmentNot documented at the engine level. The propulsion engine's standard cooling equipment includes a transmission oil cooler for an externally mounted marine reverse-reduction gear, but that gear's own oil capacity is set by the gear manufacturer/model matched to the installation, not by the engine package.Marine gear oil per the reverse-reduction gear manufacturer's specification. Where a Caterpillar-matched marine gear is fitted, Cat TDTO (Transmission/Drive Train Oil) is the typical drivetrain-oil spec used across Cat powertrain components.
Hydraulic system and tankNot applicable as standard equipment. A hydraulic pump drive is offered only as an accessory PTO; no dedicated hydraulic reservoir or tank capacity ships with the base engine package.Not specified at the engine level -- hydraulic fluid selection depends on whatever hydraulic pump/system the boat builder attaches to the optional PTO.
Grease (external linkage/governor points)Spec only -- no fill capacity; applies to external governor linkage and pivot points, not a reservoir.Caterpillar multipurpose chassis grease (general-purpose NLGI 2 grade) for external linkage and pivot points per the lubrication schedule.

Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the 3306B beyond the schedule

Predictive Maintenance & Fluid Analysis

The 3306B runs a fully mechanical fuel system with no ECM to flag problems early, so scheduled oil and coolant sampling carries more weight than on later electronic engines. Pull an oil sample at every oil change to track wear metals and fuel dilution, and sample coolant to catch corrosion-inhibitor depletion before it pits cylinder liners or the heat exchanger core. On turbocharged-aftercooled (BTA/DITA) ratings, log boost pressure and exhaust temperature each trip; a slow drift usually means a fouled aftercooler or worn turbocharger before power loss shows.

Corrective & Common Repairs

Most 3306B repairs trace back to raw-water cooling and marine fuel quality. Failed raw-water pump impellers are the most common unplanned repair, especially after lay-up or in silty rivers and brackish estuaries. Heat exchanger and aftercooler cores foul with scale and marine growth, driving high coolant temperatures under load. Water-contaminated fuel and algae growth in tanks clog primary filters and can score injector plungers. Marine gear coupling wear and misalignment with the propeller shaft also show up as vibration, and warrant a shaft-alignment check when vibration increases.

Overhaul & Rebuild Points

Cylinder liners, pistons, and rings wear steadily under sustained marine load and form the core of any 3306B in-frame overhaul, usually with main and rod bearings inspected together. Turbocharger bearings and the wastegate on BTA units wear faster than the base engine and are a common standalone rebuild. Fuel injectors lose spray pattern and calibration over thousands of hours and should be tested or reconditioned as a set. Cylinder heads need valve, seat, and guide reconditioning at major overhaul, and the marine reduction gear should be rebuilt on its own schedule.

Seasonal & Environment Servicing

Before winter lay-up, drain the raw-water side of the cooling system completely to prevent freeze damage to the heat exchanger, aftercooler, and oil cooler, and fog the cylinders if the boat sits idle for months. Change marine gear oil before storage, since moisture accumulates in idle gear cases. On recommissioning, check the raw-water strainer, inspect or replace the impeller, and re-tension belts before starting. Vessels working brackish or silty water need more frequent zinc anode and heat-exchanger inspection than fresh-water or open-ocean boats, since fouling and galvanic corrosion accelerate faster there.

3306B fault codes & troubleshooting

CodeMeaningLikely causeWhat to do
High Water (Jacket) Temperature Shutdown/AlarmCoolant temperature switch trips when jacket water exceeds the safe operating limit, closing a contact that fires the fuel shutoff solenoid or lights a panel alarm.Raw water pump failure, blocked raw water strainer or heat exchanger, low coolant level, stuck thermostat, slipping or broken drive belt.Shut the engine down if it has not already tripped; check raw water flow, strainer, belt condition and coolant level before restart; let the engine cool before removing any caps.
Low Oil Pressure Shutdown/AlarmOil pressure contactor switch closes when pressure falls below its set point, tripping the fuel shutoff solenoid or sounding an alarm buzzer/light.Low oil level, plugged suction screen, worn oil pump or a bypass valve stuck open, worn main or rod bearings, air leak on the pump suction side.Stop the engine, check oil level and look for external leaks, inspect the suction screen and filter, and verify pump condition before restarting.
Overspeed ShutdownA switch mounted on the tachometer drive trips when engine speed exceeds the rated overspeed limit, cutting fuel at the shutoff solenoid; recovery needs a manual reset button push.Governor linkage binding or failure, sudden loss of load such as marine gear disengagement or clutch slip, a sticking fuel rack.Do not restart until the cause is found; inspect governor linkage, throttle cable and marine gear engagement, then press the reset button before restarting.
Charging System / No-Charge AlarmPanel ammeter or charge light shows the alternator or generator is not supplying charging current to the battery.Broken or slipping drive belt, failed alternator or regulator, loose or corroded wiring at the alternator or battery.Check belt condition and tension, inspect wiring connections, test alternator output and replace components as needed.
Low Coolant Level Alarm (where fitted)A float or probe switch in the header/expansion tank signals when coolant drops below a safe level, ahead of a high-temperature trip.External coolant leak, weep at the water pump seal, loose hose clamp, gradual loss from an aged cooling system.Check hoses, water pump and heat exchanger for leaks, top off with the correct coolant mix, and confirm no further loss before returning to service.

Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.

3306B attachments & work tools

Marine gear / transmission coupling

Engine uses an SAE No. 1 flywheel housing with an SAE No. 14 flywheel, the standard coupling interface for marine reduction/reverse gears in this power class. Twin Disc-type marine gears are commonly paired with it; exact gear model and reduction ratio vary by boat builder and installation.

Cooling system option

Standard propulsion/auxiliary build is heat-exchanger cooled, with a gear-driven, self-priming centrifugal sea water pump (rubber impeller) and corrosion-resistant heat exchanger tubes. A keel-cooled configuration (external hull piping, no raw-water circuit) was also fitted on some vessels; cooling method varies by installation.

Exhaust system

Standard exhaust is a water-cooled manifold and turbocharger fitted with a dry elbow. A wet (mixing) elbow, flexible exhaust fittings, and rain cap are offered as accessory equipment for boats needing a wet-exhaust discharge run.

Accessory / PTO drive

Front gear-train accessory drive accepts a spline- or taper-shaft-mounted pump running at engine speed; an alternate flywheel housing with a rear accessory drive is also offered for mounting a hydraulic pump or similar auxiliary equipment. Drive capacity is limited by front gear-train loading, so pump sizing should be confirmed against the class rating.

Instrument panel and controls

Standard equipment is an engine-mounted panel with oil pressure, water temperature, and fuel pressure gauges plus a service meter, along with flexible fuel line connections. A remote/bridge-mount panel is available as accessory equipment for helm installation.

Alarm and protective shutdown

Accessory equipment includes an alarm contactor for low oil pressure and high water temperature, plus electric shutoffs for oil pressure, water temperature, and overspeed conditions, used where unmanned engine room or classification-society requirements apply.

Engine mounting

Resilient, two-piece isolation-type mounts are used to dampen vibration and shock and to isolate the engine from the hull structure, standard practice for marine diesels in this class.

Factory duty/rating configurations

Offered in three rated arrangements published on separate spec sheets: propulsion (direct or reduction-gear drive), auxiliary (belt- or PTO-driven pump/equipment set), and genset (generator drive). Continuous/intermittent ratings for the class span roughly 163-269 kW (218-360 mhp) at 2000-2200 rpm depending on duty rating and configuration.

Governor

Standard governor for this engine generation is a mechanical, adjustable flyweight/dashpot type providing speed control without electronic engine management.

3306B serial number reference

The serial/PIN plate for the 3306B marine engine sits on the engine itself, typically on the valve cover or intake side of the block; it lists the engine serial number (ESN) and usually the arrangement number (AN) for that specific build, and the number can also be stamped into the block on the left-hand side. The serial number is 8 characters total: a 3-character prefix identifying the model and build/arrangement family, followed by a 5-digit unit number that runs roughly chronologically within that prefix — match the prefix first to confirm which 3306B marine family and configuration (propulsion vs auxiliary/genset) the engine belongs to, then use the digits to place it within that range.

Frequently asked questions

What engine is the Caterpillar 3306B?

The 3306B is itself the engine: a direct-injection, inline six-cylinder Cat diesel of about 10.5 L (638 cu in) displacement, built in turbocharged (BT) and turbocharged-aftercooled (BTA/DITA) marine versions. Cat rated it for propulsion, ship-service auxiliary, and generator-set duty, with marine outputs spanning roughly 163-268 kW (218-360 mhp) depending on rating class and configuration.

How much does a Caterpillar 3306B marine engine weigh?

Dry weight runs from about 1,030 kg (2,265 lb) up to roughly 1,120 kg (2,469 lb), depending on whether it is set up for propulsion, auxiliary, or genset duty and which cooling package (heat exchanger or keel-cooled) it carries. Check the nameplate or spec sheet for the exact figure on a given configuration.

What replaced the Caterpillar 3306B?

Cat followed the 3306B with the 3306C, an updated version of the same mechanical platform, before phasing the family out in favor of electronically governed marine engines, the C9, C-10, and C-12, as emissions rules tightened through the late 1990s and early 2000s.

What 3306B owners discuss

How long does a Cat 3306B marine engine typically run before it needs a major overhaul?
Well-maintained 3306B marine installations commonly reach 20,000+ hours before a major inframe or out-of-frame overhaul, and that figure climbs further in genset or light-load propulsion duty. Real-world life depends heavily on rated horsepower and duty cycle: a low-output trawler engine run gently outlasts a high-output workboat rating pushed hard for years. One long-serving unit was reported around 5,500 hours with tight compression, low oil consumption, and no start-up smoke. Treat quoted hour totals as a starting point, not a guarantee, and weigh them against an oil analysis and a compression check.
What marine configurations did the 3306B come in, and why does it matter for a buyer?
The 3306B marine line covers naturally aspirated and turbocharged builds, plus turbocharged-aftercooled versions cooled either by jacket water through a heat exchanger or by raw water routed directly through the aftercooler. Rated output across the line runs roughly 163-268 kW (218-360 hp) at 2,000-2,200 rpm depending on the specific rating. Cooling architecture differs enough between these builds that aftercooler cores, raw-water pump components, and heat exchanger cores are not interchangeable across all of them. Before diagnosing a cooling complaint or sourcing parts, confirm which cooling configuration is actually fitted, not just that it is a 3306B.
Owners mention the 3306 family burning oil at idle or light load. Does that affect the B series?
Yes, it is a recurring complaint tied to 3306B-powered boats: oil consumption rises noticeably at light loads and idle, more than owners expect from an engine that runs clean under load. Caterpillar revised the piston and ring package during the production run to reduce this, so how much a given engine is affected varies by build date and which piston design it received. If a 3306B smokes blue on light throttle after sitting idle, do not assume it is terminal. A compression or leak-down test will show whether it is worn guides and rings or something simpler, like a turbo passing oil into the intake.
What cooling-system issues come up most in raw-water-cooled 3306B installations?
Raw-water side fouling is the recurring theme: impeller wear, scale or debris blocking the heat exchanger or aftercooler tubes, and pieces of a sacrificial zinc anode breaking loose and lodging in the tubes. A properly flowing raw-water circuit shows a modest, consistent temperature rise across the exchanger; a much larger rise points to restricted flow rather than a thermostat or coolant problem. Steel engine mounts are also prone to rusting away in a bilge environment and get overlooked until badly wasted. Because an ignored raw-water restriction leads straight to an overheat and possible head gasket or liner damage, have your dealer or a marine diesel mechanic verify raw-water flow and mount condition on any inspection.
What's distinctive about the 3306B's governor and fuel system, and what causes hard starting?
The 3306B runs a hydraulic-servo governor that uses engine oil pressure to move the fuel rack, a mechanical design that predates Caterpillar's later electronic governor options on this engine family. Owners report hard starting after a boat sits idle for several days, with cranking for 30 seconds or longer before the engine catches, consistent with fuel drainback rather than a dead battery. On these mechanical-injection engines, corroded wiring harness connectors at the fuel shutoff solenoid, weak charging-system grounds, or a solenoid and rack sticking from restricted travel are the usual suspects. Confirming the rack moves freely to the run position and checking solenoid voltage narrows it down quickly. Because a rack or governor fault affects engine shutdown as well as starting, have your dealer verify governor and solenoid function rather than relying on a workaround.
Are there known issues with the exhaust manifold, turbo, or aftercooler on marine 3306B engines?
Across the 3306 family, including turbocharged-aftercooled B-series marine builds, owners and mechanics report exhaust manifolds cracking from age and corrosion, accelerated by a salt-air or salt-water environment. The water-to-air aftercooler fitted to turbo-aftercooled variants is prone to internal scale buildup from coolant deposits and, with age, a cracked core that causes coolant loss and visible exhaust smoke. Keeping the correct coolant and additive package, watching coolant level, and periodically checking turbo boots and clamps for looseness are the preventive basics owners cite.
What should I check before buying a used 3306B marine engine?
Start with the outside of the engine: heavy corrosion, failed paint, or a generally neglected appearance is a reasonable proxy for how the rest of maintenance was handled. Pull the oil dipstick cold and again after a run; milky oil signals water intrusion from a raw-water leak, head gasket, or liner seal, while a burnt smell is a bigger flag than simple dark oil. Check belts and hoses for cracking, abrasion, and corroded clamps, and ask for maintenance records, especially any history of overheating, since that predicts head gasket and liner problems more reliably than hour count alone. A spectrographic oil analysis and a proper engine survey with a blow-by check give the clearest picture of internal condition before committing. Given how much a hidden overheat history or worn liner can cost to put right, have your dealer or a qualified marine diesel surveyor verify compression and oil analysis results before purchase.

Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
