I'm looking at two Tollycraft 40' Tri-Cabins, both the same vintage and in the same approximate condition. One has the original twin 1974 Cat 3208 engines with ~3,500 hours each. The other 1974 boat was repowered in 2006 to Yanmar 6LPA-STP engines, which have ~750 hours on them.
The seller of the boat with the Yanmars is asking $35,000 more than boat with the original Cat 3208s. That seems like a large premium. But a surveyor I know says he wouldn't pay more than a $7-10K premium for the newer engines. That seems like a very conservative premium.
What's the right way to think about the value of the newer Yanmars vs. the original Cat 3208s?
I'm not looking for a debate of Yanmars vs Cats, just more generically how to value repowered (but used) engines.
