"I am hoping someone can give me some advice here. I discovered a powerboat for sale which I am interested in buying. I am only interested in the hull as I would re-power it with a single diesel/v-drive configuration. The boat is configured with twin 454 engines with Bravo II outdrives. According to the owner, the boat has sat for over ten years. The owner informed me that the engines in the boat were new before the boat was mothballed. Both 454’s were rebuilt by a company call Enginetics, bored 60 over, which places it(I guess) at a 468, and have hi-perf cranks and lifters…? He states that they produce 500 hp each after balancing and blueprinting and were never started after installation. That was ten years ago. When I closely inspected the engines, I noticed both engines were not even bolted to the motor mounts and all intake and exhaust ports sealed. So I have two 468 engines w/ transmissions that were “new” when installed but sat for ten years. My questions or concerns are follows: having the engines sit for this extended period, would the engines be rendered useless and have to be overhauled all over? Is there any further assessment that I can do to ensure that they aren’t locked-up? I don’t want to spend any money on these engines as I am desiring a single diesel. How do I determine the motors worth? Any advise would be appreciated."
