Hi....dipping my toe into the trawler pond here in British Columbia...currently looking very hard at a Bestway 39 ... survey checks out but the single Ford Lehman has 9000 hours on it...is it almost too many hours?
Welcome! I'd say yes, *almost*, depending on what has already been said. If it has been religiously maintained, and has even had a top end rebuild, you could be just fine for several more thousand hours.
The Ford Lehman can be a 20,000 hour engine per Bob Smith before he passed away. He certainly knew the engine well. It all depends on how it has been maintained. However, it probably would not have made it to 9,000 hours if it has not been taken care of. I would find an experienced Lehman mechanic to survey it since it does have lots of hours.
