Known problems for this model
-
Teak decks screwed through to balsa sub-deck deck
Until 1985 the teak planking was fastened through the fiberglass into a balsa-cored sub-deck, a chronic source of leaks and wet core. Later boats have solid fiberglass decks.hmy.com
-
Plywood deckhouse on early boats deck
Boats built before 1975 have a plywood cabin house covered in fiberglass cloth, prone to rot where water gets in.hmy.com
-
Leaking teak window frames deck
Teak-framed windows (dropped in 1992) and poorly bedded windows generally are a common leak source on Taiwan trawlers; look for stains and rot below sills.hmy.com · pacificyachting.com
-
Welded steel fuel tanks fuel
Older Taiwan trawlers commonly have welded steel tanks that leak at corners and seams as they age; replacement usually means cutting them out in pieces.pacificyachting.com
-
Wet stringers hull
Holes drilled through wood-cored stringers for wiring or plumbing let bilge water in; rotted stringers let the hull flex and upset engine alignment. Have the surveyor moisture-test them.pacificyachting.com
Engines & parts
Ford Lehman 135 / SP135 (2725E) parts: good
Factory standard engine — you entered “Ford Lehman 135”
Based on the later Ford 'Dover' 2725E 6.2 L naturally aspirated six (Ford built the Dover series 1982–1994, then Otosan/Dovertech to 2005). 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. Do not assume 120 (2715E) and 135 (2725E) internals interchange.

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
