Tank capacities — where the figures come from
-
Fuel 320 gal
“Fuel Tank: 320 Gallons (1211.33 Liters)” — search excerpt (1989), rcryachts.com · “Fuel Tank: 320 Gallons (1211.33 Liters)” — search excerpt (2002), murrayyachtsales.comListings for a Taiwan-built 1989 and a Nova Scotia-built 2002 boat agree; no builder document found.
-
Water 120 gal
“Fresh Water: 120 Gallons (454.25 Liters)” — search excerpt (1989), rcryachts.com · “Fresh Water: 120 Gallons (454.25 Liters)” — search excerpt (2002), murrayyachtsales.comListings agree.
-
Holding 45 gal
“Holding Tank: 40 Gallons (151.42 Liters)” — search excerpt (1989), rcryachts.comOne listing says 40 against our earlier 45 from a spec database; a single listing isn't enough to change it.
-
Water heater unknown
“6 gallon hot water heater” — search excerpt (2000), trawlerforum.comOnly one boat's for-sale post, on TrawlerForum, gives a size.
Tanks are often replaced or added on older boats — check the tank labels or a survey for yours.
Thrusters and steering — where this comes from
-
Bow thruster unknown
“hydraulic fluid leaks (from either the steering system or my hydraulic thrusters)” — search excerpt, groups.ioOne owner on the Monk 36 Owners Association list mentions hydraulic thrusters on his boat; it's a single boat.
-
Stern thruster unknown
Nothing specific to this model was found.
-
Steering unknown
“hydraulic fluid leaks (from either the steering system or my hydraulic thrusters)” — search excerpt, groups.ioAn owners' association thread on hydraulic steering shows it on at least one boat, and the Soundings review doesn't describe the steering. That isn't enough to go on for a model built in Taiwan and later Nova Scotia.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on first year, last year, number built — left blank rather than guessed.
Solid fiberglass aft-cabin trawler with skeg-protected prop. Early Taiwan boats have lots of exterior teak (decks, window frames, hatches); Nova Scotia boats have teak handrails only. Post-1992 boats dropped the aft-head tub and moved the master berth off the hull side. Built in Taiwan from the early 1980s, then in Nova Scotia from the early 1990s until about 2007-08; over 250 built. Taiwan-era engines were mostly 135 hp Perkins or 150 hp Cummins, with many other options including Lehmans and a dozen-plus twins; later boats had a 220 hp Cummins (9-10 knots). Designer credit (Ed Monk) and any Hatteras or McQueen builder connection were not confirmed by the sources read.
Engines fitted

Boats of the same model can differ — check which engines yours actually has before ordering parts.
Generator
often added later
“Onan 9KW generator” — search excerpt (2000), trawlerforum.com · “Onan 9 kW generator” — search excerpt (2002), curtisstokes.net · “Onan 8.5 kW generator” — search excerpt (2004), curtisstokes.net
No builder document was found for either the Taiwan or Nova Scotia builds. The often-added-later label comes from boats for sale; on the later boats the Onan sets were more likely builder- or dealer-installed options.
-
Onan — 9 kW
often added later
Seen on a 2000 and a 2002 Nova Scotia-era boat; a 2004 boat has an 8.5 kW Onan. Fuel not stated (diesel likely on a diesel trawler, not confirmed).“Onan 9KW generator” — search excerpt (2000), trawlerforum.com · “Onan 9 kW generator” — search excerpt (2002), curtisstokes.net

Engines & parts
Ford Lehman 120 (6D380 / 2715E) parts: good
Factory standard engine — you entered “Ford Lehman 120 / 135”
Marinized by Lehman from the Ford of England 'Dorset' 2715E six-cylinder (380 cu in) industrial/truck diesel; Ford built the Dorset base engines 1964–1984. Base-engine internals interchange with the Ford 2715E, and marine-specific parts (raw water pumps, heat exchangers, injection elbows, gaskets, lift pumps, air filters) are widely stocked. American Diesel Corp (founded by former Lehman people) still sells parts, publishes spare-parts lists and gives technical advice. Rebuilt and used 120s are also sold by salvage yards.

Common problems (2)
-
Chronic oil leaks engine
Most 120s weep oil somewhere; owners often trace it to the rear of the engine near the heat exchanger (head/head gasket area) or to the drive seals of the gear-driven injection pump. Moderate oil use is treated as normal on these engines.trawlerforum.com · marineengine.com
-
Fuel leaks at injection pump, lift pump and return lines fuel
Slow diesel drips usually come from loose bleed screws or banjo washers, perished rubber injector return hoses, a failing lift-pump diaphragm, or worn internal seals in the Simms or CAV injection pump, which needs a pump shop to overhaul.yescenters.com

Perkins 6.354 / T6.354 parts: limited
Factory standard engine — you entered “Perkins 6.354 (135 hp)”
Inline six of about 354 cu in, naturally aspirated or turbocharged (T6.354.4 around 240 hp). TAD still builds complete marinized 6.354 packages and sells parts; owners on the Hatteras forum report some parts for older versions getting harder to find and marine cooling parts (multi-cooler, heat exchangers) being expensive.
Parts sources: Trans Atlantic Diesels (TAD), Perkins official parts shop
Common problems (2)
-
Persistent oil leaks engine
Owners describe the 6.354 as a habitual oil leaker because of its seals, meaning regular bilge cleanup.samsmarine.com
-
Multi-cooler and heat exchanger costs cooling
Mixed metals in the raw water circuit mean frequent heat exchanger and gasket work, and the turbo model's multi-cooler is a known weak and costly part.samsmarine.com

Cummins 4BT 3.9 parts: good
Factory standard engine — you entered “Cummins 4BT 3.9”
Four-cylinder B-series engine shared with countless delivery vans and industrial uses, so base parts are available almost anywhere. TAD sells Cummins factory ReCon 4BT 3.9 marine packages; Seaboard Marine stocks 4BT marine parts.
Parts sources: Trans Atlantic Diesels (Cummins 4BT ReCon), Seaboard Marine
Common problems (2)
-
Rough idle vibration and mount fatigue engine
The 4BT is considered very reliable but shakes noticeably below about 900 rpm; good isolation mounts help, and mounts can fatigue or break over time.trawlerforum.com
-
Water in fuel damaging injectors fuel
Water or salt water getting into the fuel system corrodes the injection components, so filtration and water separation matter.justanswer.com

Cummins 6BT / 6BTA 5.9 parts: good
Factory standard engine — you entered “Cummins 6BT 5.9”
Mechanically injected 5.9 L inline six from the Cummins B-series truck/industrial family, so base-engine parts are everywhere. Cummins still sells factory ReCon (remanufactured) marine 6BT/6BTA engines (152–210 hp ratings) with a 2-year/2000-hour warranty. Seaboard Marine is the best-known marine specialist, selling aftercooler/heat-exchanger service kits, upgraded raw water pumps and technical guidance; TAD also sells Cummins packages.
Parts sources: Seaboard Marine, Cummins (ReCon 6BT/6BTA), Diesel Pro Power
Common problems (2)
-
Aftercooler corrosion letting seawater into the intake cooling
On the turbo-aftercooled 6BTA the seawater-cooled aftercooler core has vertical tubes and an aluminum housing that corrodes from condensate; a leak can put salt water into the cylinders and wreck the engine. Owners pull, clean, grease and pressure-test the core every few years and fit new O-rings.trawlerforum.com · sbmar.com
-
Heat exchanger and aftercooler service cooling
Routine seawater-side service (O-rings, gaskets, zincs) is a recurring owner job; kits are sold for it and refilling coolant without trapping air is a common question.sbmar.com · sbmar.com

Caterpillar 3116 parts: limited
Factory optional engine — you entered “Caterpillar 3116”
Supported by Cat dealers by serial number; aftermarket rebuilders (e.g., Big Bear Engine) sell parts and address known problems. Some 3116s built in France ('soft block') were problematic and owners are told to check serial numbers with Cat.
Parts sources: Big Bear Engine Company, Diesel Pro Power
Common problems (4)
-
Failures in high-load use engine
3116s generally do fine in trawlers but problems show up in fast boats run near full power for long periods; poor propping that overloads the engine ages it quickly.trawlerforum.com
-
'Soft block' engines engine
A batch of French-built blocks had a reputation for early failure, sometimes within a few hundred hours.trawlerforum.com
-
Injectors, fuel rack and heads fuel
Owners and rebuilders report injector/injector-cup, fuel rack and cylinder head problems; good maintenance history matters when buying.4btengines.com · facebook.com
-
Low turbo/exhaust mixer height exhaust
The low-mounted turbo and exhaust mixer make it harder to get adequate exhaust riser height, so the exhaust installation needs care to avoid water backflow.trawlerforum.com
