Thread: PROP ON ALPHA

    I have a friend who has a 21 ft. Cheeta with 350 chev and is using a 21 pitch alum. prop, the boat does 47 at 5100 rpm. is this about the right rpm and speed or would a s/s prop of the same pitch perform better? can this boat use more pitch and get the rpm down and still attain the same speed, any info is welcome.

    I had a 19P Ballistic. It is a different shape and looks funky, but out of 6 props, the is the one Eliminator settled on for my 215 skier with an Alpha drive. Got me 300 Rpms and 4 mph.

    Instigator28-Is that a 4 blade or 3 blade? Was it reworked or out of the box that got you those numbers?

    It was right out of the box. 3 blade if my memory serves me correct, but I can't be sure. It looks like a normal prop but then someone went and cut the edges off. Eliminator actually took the boat to Paris lake and tried several and said this was the best. If I were to get a 21' boat again, I would go out and get another. It was also very very good and pulling skiers out.
