I have a 26 Eliminator Daytona and blew the lower end and it had 1.50 gears. I replaced the entire outdrive with one that has 1.36 and not sure what way to go with the prop. Let start with the boat its 700 hp had a XR standard length and a 32 labbed bravo. The boat cavitated and blew out trying to get on plane. At 5150 im at 93-94 with im sure alot of prop slip. I need help and thanks. 5 Blade?????

best I can figure is, you will need to drop to a 28 or 30P.
you are running about 10% slip with the 1.5's, so figuring that,
28P= 5350 rpm (1.36 and 10%) at 94mph
30P= 5000 rpm (1.36 and 10%) at 94mph
check out this web site, it might help a little.
