Inboard options 6.0 vs 5.7 vs Diesel

[OSEAD23]

Thanks guys! Does anyone have an idea of what a yanmar by260 costs? i think that may be what you are talking about as thats their new engine in that size..
that looks like the best option in a yanmar. BTW it weighs less than a 5.7 gas engine by 200lbs too.

any other ideas on other diesels in this size range?
