Prop size / pitch for 32+2 CB

Post by Doug »

I want to be sure I have the correct prop on our 32+2 CB. This is a 4 blade prop and the engine is a Cummins 6BTA 370 HP Turbo. If anyone knows what the size and pitch of the correct prop for this boat, please let me know.
Thanks,
Doug

Are you getting proper RPM at WOT? I believe you should be turning 2800rpm fully loaded but you may want to double check that.

The 6BTA 370 is rated at 3000 rpm. You want to be spinning at least 3100 when loaded for bear.
Make sure your tachs are calibrated before you report your WOT rpm. :wink:

My prop is a 22 LH 21. Is that the correct prop?
