Tank capacities — where the figures come from
-
Fuel 800 gal
No builder document was found. A 1983 boat's listing says 800 gal, matching the HMY powerboat guide.
-
Water 400 gal
The same 1983 listing says 400 gal, matching.
-
Holding 60 gal
The 1983 listing gives a 75 gal holding tank, but that's one boat, not enough to change the HMY powerboat guide's 60.
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
No source found that mentions a bow thruster.
-
Stern thruster unknown
No source mentions a stern thruster.
-
Steering unknown
“Replaced cable steering system w/SeaStar hydraulic steering w/autopilot capability (2012)” — broker listing (1980), denisonyachtsales.comOne 1980 boat's listing says its original cable steering was replaced by SeaStar hydraulic in 2012, which hints that early boats had mechanical cable steering, but one listing isn't enough to go on. No free builder brochure (a 6-page 1980s one is sold as a paid item) or review was found.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on first year — left blank rather than guessed.
The company's most popular boat until a late-1996 factory fire destroyed the molds. Built in China on a solid fiberglass hull; three staterooms with galley aft in the salon. Teak decks (including aft deck and bridge), handrails and transom. Older boats have twin 135 hp Lehmans (8-9 knots); twin 210 hp Cummins later became standard (10 knots); 375 hp Cats cruise 16 knots.

Ford Lehman 120 — 120 hp, diesel, twin
standard
Listings for a 1981 and a 1983 Flush Aft Deck give twin 120 hp Ford Lehmans (the 1983 listing calls them model 2725E, a code usually tied to the SP135, while still stating 120 hp).Sources: boatshed.com · denisonyachtsales.com

Caterpillar 375 hp diesel (model not named by source) — 375 hp, diesel, twin
factory option
HMY: 375 hp Cats cruise about 16 kn, 20 top.Sources: hmy.com

Volvo Penta TAMD60B — 230 hp, diesel, twin
factory option
A 1980 Island Gypsy 44 flush aft deck listing has twin Volvo TAMD60B at 230 hp each; single listing, and it does not say whether they were factory-fitted.Sources: sysyachtsales.com
Boats of the same model can differ — check which engines yours actually has before ordering parts.
Generator
One 1980 boat for sale has an Onan 17 kW fitted new in 2000, replacing the original; the same listing says the boat's original AC system was 220 V/50 Hz, which later owners rewired to 60 Hz. A 1979 owner on TrawlerForum refers to an old Onan. No builder list found.

Engines & parts
Ford Lehman 120 (6D380 / 2715E) parts: good
Factory standard engine — you entered “Ford Lehman 120”
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

Parts are sold by the same Lehman specialists as the 120; American Diesel lists spare-parts sheets and Go2marine stocks cooling parts, heat exchangers and elbows for the 135.
