After looking through this forum for quite a while, there's obviously alot of talented people on this board. I enjoy reading every bit of it. My question is about the best engine for a jacuzzi 12wj with a B impeller (think it's a 'B' cause of the impeller diameter, for the part # cast into it sure doesn't match up to the jacuzzi parts list at Northern Marine.) It's gotta be Chevy, but I'm wondering what RPM and HP I should reach for to use the impeller I've got. I want it all, but I think reliablity wins in the end. The boats a very shallow v, 16' loa, and the cockpit has lots of room thanks to a slightly short deck. I was thinking bb, but maybe a small block 383 would work. Whadayou guys think?
thanks.
After talking to Jack at MPD about my WJ with a B impeller i found out it the Jacuzzi B is close to a Berk A. The berk charts will help you place the HP to Impeller. My healthy 455 with dual 660s turns an MPD prepped WJ B to about 5200 RPMs.
Sorry I dont have the chart handy but im sure someone will chime in with it.
