Known problems for this model
-
Leaking fuel and water tanks fuel
Buyers of 1980s DeFever 41s are told to check fuel and water tanks for leaks first; welded steel tanks on Taiwan trawlers tend to fail at seams and corners, and removal usually means cutting them up.trawlerforum.com · pacificyachting.com
-
Rudder and shaft crevice corrosion running gear
Stainless shafts and rudder stocks on boats this age can suffer crevice corrosion; along with struts and shaft logs they are standard pre-purchase checks.trawlerforum.com
-
Teak decks and window leaks deck
Teak decks and leaky windows are the classic Taiwan-trawler weak spots; water pools under the planks and finds screw holes into the core, so probe for soft spots and look for stains below window sills.pacificyachting.com
Engines & parts
Ford Lehman 135 / SP135 (2725E) parts: good
Factory optional engine — you entered “Ford Lehman 135 (twin)”
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.
