I am looking to import a Post 40 to New Zealand, which has twin Crusader Gas engines, which I will replace with Diesels once here.........therefore a couiple of questions 1- Is there any particular area of a wooden Post40 that I should be more particular when inspecting. 2- Has any one done a diesel transplant into these? How did it go 3-What shaft diameter did these boats run The boat is in Narrows CT, anyone in that location know of a good surveyor We are $2.00 a litre here! Thanks in advance Glen
Hello Glen, Small world. The engines are actually Chryslers not Crusaders, and she is located at Kent Narrows (Chester) Maryland which is just across the Chesapeake bay from Annapolis, about an hour from Washington DC, or 40 minutes from BWI Airport. The wooden Post 40 is, I believe planked with cedar, so rot should be at a minimum with the boat. She is a soft chine, Jersey Shore build so the steam bend oak ribs can be suspect, along with the fastenings. Both should be checked carefully. When new, the diesel options for this boat were big V-8 4 cycle diesels. Both Cummins (model 504 and 555) and Caterpillar (model 3160, forerunner to the 3208) were offered. The engine beds and space avaiable should be OK for a direct diesel repower. Depending upon what diesel you choose, the exhaust ports may need to be larger diameter. The existing shaft size is a question that can be answered at inspection or survey. The fuel tank, a known weakness in these boats, has been replaced. The material of it's construction and compatibility with diesel needs to be confirmed. There are several surveyors in the Eastern Shore/Kent Narrows/Annapolis area that can do a good job in looking her over for you. I can make some suggestions by PM or e-mail. Are you planning to visit the US to inspect this boat in person?
Glen, The shafts were one and a half inch on mine with 504 cummins. I would watch the weight carefully. I think the new lightweight diesels may lighten the hull up too much.
