I am new to this forum and hope I'm doing it correctly!
A bit about me. My name is Ted and I currently live in Navarre, Fl. Until this spring I owned and lived aboard for 4 yrs (6 mos out of each yr) a 32 ft Sedan Bridge Marinette with twin 318 Marine Chryslers. It was a great boat but was time to sell it. Well I'm now looking at a 1986 40 ft. Aft cabin Mainship, with two turbocharged 8.2 liter Allison (Detroit) diesels. From my limited research this was Detroit's attempt to build a 4 stroke (instead of their normal 2) diesel. I know many went into buses and other road vehicles and later went into some boats as well. The early ones I know had head gasket, cooling, and a few other problems. BUT it appears the later models had these problems resolved? Yes/No? So my question to whoever has info on these motors is the 1986 version a better 8.2 then earlier ones? Also any comments regarding these motors would be appreciated. Thanks a bunch and looking forward to any comments!
