"I was told that the 1984, 454
"I was told that the 1984, 454, Crusaders (800 hours) in the vessel I'm looking to buy ran great and had good compression (130 or better) according to the owner. Prior to a full survey, I had a compression test done by the marina. This compression test by the marina mechanic told a much different story. The Port engine had cold compression between 60 and 70 in all cylinders, while the Starbord engine was even worse (one cylinder had a compression of 30). The mechanic said that he couldn't believe the vessel even made it to their marina for winter storage with compression readings so low. I can get my full deposit back and was ready to walk away from the deal when the mechanic said that he wanted to try another compression test after the boat was launched and ran until the engines are at operating temperature. The owner agree to pay for everything (launch, second compression test, etc.). Mechanic said maybe something caused the low readings that running her may solve. I'm ready to walk away from the deal, but my wife likes the boat. I've got nothing to lose. What do you think? Could something have caused these low readings that could get straightened out by running her? If the readings improve to acceptable levels, how do I know that there isn't still something seriousely wrong with these engines? If the second test still shows poor compression, I guess I could lower my offer to a point where I could have the engines rebuilt or replaced. Anyone have any idea of what it would cost to have the marina remove, rebuild, replace these two engines. I would really appreciate any of your thoughts or opinions as to what I should think or do.
