Props for 1988 357 ?
 
Bought the boat last year and finally got it in the water. Both engines ended up being trashed. After alot of frustration, I decided to stroke the old 420's to 496. Nothing crazy, everything new except head castings and intake. We did go to roller cam with 4/7 swap, 9.2:1 cr, Stainless Marine exhaust,etc.
After getting all those bugs out, ran 65 /gps with 21 pitch Turbo props. Maxed out rpm at 5600. So, what do you guys think ? Go Bravo 1 24P for the stern lift or go with the Mirage Plus 25P ? Trying to get the rpm down around 5000.
Thanks, BC

not sure you can spin 24 or 25...

try 23 3 blades, it should lower pretty much.. I'd say 300 rpm.

how much gas / person on board?
