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 & 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.

  • 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.
