Help on new blades

Post by Basin_Runner355 »

Hey guys i need some help. I’m looking to upgrade to a 3 blade I’m looking torn between the wisper tip 2.0 and the Sensenich jw 76 inch. I’m in the ball park of 425 hp and 430-440 torque so i think i can turn it. 2:1 century belt drive on a 14x7 diamond back.

The L80JW series would be a better comparison to the 2.0

This prop will work very well on your setup.

Thanks.

Well i pulled the trigger on a brand new set of sensenich 80jw cut down to 78. Will
Let y’all know. How it does. Guy at sensenich said theses blades were built for 350-450 range boats with the 2:1-2.3 reduction. Said those blades are the best for my set up.
