Hello

We have the 370hp for sure.  From a Cummins bill it reads...   B5.9-M3 (370)   CPL220800   
Re-pitched the 3 blade props to factory and last year, will keep as spares.    Put on the below props last year.
Acme cnc machined props 24x28x4 blade nibral
the 4 blade props turn 3050 with a full load.  Handle beautiful around the marina and I gained 2 mph in our normal cruise speed, 2500 rpm's which gives about 28 mph or close to 25 kph

I will look into the rpm situation again this spring.  

Thanks
Kent
