Can someone share performnace data/info or experience with the Cummins 330B Diamond series engines?

Thanks in advance ...\\

I don't have any real fuel burn data but the 330 in the 31 gets about 29 knots top end.
A bit less than the 315 Yanmar.

Exhaust system is 6" and can be tricky to install depending on who's deck system you have and whether you want it to run outboard of the stringer.
Quite expensive having the risers made.

Tighter fit in the ER.

Might have trouble fitting under some er boxes.

All in all a good engine though for the right application.

In my opinion not for the 31. Installation costs quite a bit higher than say for the 315 Yanmar or 250 Cummins.
