Re: have 1996 celebrity 5.7L alpha what prop for maximum holeshot?
I recently went from a 19 pitch 3 blade SS on a 21' Sea Ray 5.7 Alpha to an 18 pitch 4 blade aluminum (wanted to see how it performed before springing for stainless). The boat is quicker out of the hole, and I'm able to run on plane at about 200-250 less RPM. Top speed is about the same, as I was also able to pick up about 400 on WOT - probably a result of going aluminum as opposed to SS.
