Known problems for this model
-
Wet foam core in the hull bottom hull
Earlier 42s have a cored hull below the waterline; thru-hulls or transducers added without sealing the core let water in, and some cores have been found soaked. Moisture-test the bottom at survey.trawlerforum.com · forums.sailinganarchy.com
-
Screwed teak decks over cored deck deck
Caulking and bungs must be kept up or water gets into the deck core; boats whose teak has been removed and glassed over are valued higher. Hulls before #65 have glass-over-plywood decks.trawlerforum.com · hmy.com
-
Salon window and pilothouse door leaks deck
Look for water staining around salon windows and the pilothouse doors and windows.trawlerforum.com
-
Hard-to-reach holding tank plumbing
An original holding tank that has not been upgraded is a major job to replace because of poor access.trawlerforum.com
-
Hull bottom deflection on early boats hull
Some late-1970s and early-1980s cored hulls developed bottom deflection, which led the builder to switch to solid glass below the waterline; the PVC core does not rot but can take on water at penetrations.trawlerforum.com
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
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.
