I just recently was given (if I want it) an F26 Trojan. The boat is currently in the water at a slip about 2 hours from here. The guy claims that there is water getting into the oil. The engine is a 318 Chrysler. The boat was kept in brackish water in the Hudson River north of NYC. The boat appears to be in good shape with the exception of the engine. Any advice on if I should get involved in this project. What can I expect to find on a 40 year old boat?
