Tried searching but could not find the answer to a question about the maximum diameter prop for an Alpha 1 drive.
Have a 21' Seebold sport boat with a Mercruiser 260 (Chevy 350). Hull is a pad-keel, step-transom design similar to many bass boats. Currently use a Stiletto 14.25x23 prop for general use. Top RPM's are ~4600 and its a good all-around prop that provides great performance and fuel economy. Top speed is ~60MPH, but hole shot is a little slow.
Looking at options for a lower pitch ski prop, probably aluminum. Thinking 4 blade with large diameter. Have plenty of power...so trying to use that power to create pulling torque. Could use lower planing speed also...we have a parasail we sometimes pull and we find that we need to stay right at minimum planing speed, which is awkward to control.
What is the largest diameter prop that will fit on an Alpha 1 that already has the narrow trim tab needed for a S/S prop?
Any recommendations for my application? I'm thinking a 19 pitch 4-blade in the largest diameter I can fit, and probably a standard aluminum prop in the under $150 range.
Thanks!
