Default Re: Recommendations for a re-power of a SF23 Inboard?

A yanmar 4cyl is currently rated at 260hp and really sips gas. Almost bulletproof, too. You may or may not need a tranny and trolling valve because at idle you will be going 5+kts. You are looking at 20-25k for sure unless you can find a running take out. Also there is a guy somewhere perhaps in texas that marinizes 5.9litre cummins and they are about 12k or so but don't quote me on that.
