I just dynoed 509 bbc 628 hp 600 fpt. This weekend were installing It into my 25' daytona bravo one 1.5. Need help with prop and estimated speed

Wont really matter much unless you upgrade to a XR drive at least. That bravo will be lucky to make it past prop testing.

I must be very lucky. My buddie is running 540/620 for 2 years on a 25 sunsation, with a bravo one 1.5/28 lab finish @5500 . and I had a 28 donzi also power by 540/580 ran that for 4 years ( got to go easy)thay last!

My former 25 Daytona was running 650 hp thru a Bravo for 7 years, without a single problem. I was spinning a labbed 32 pitch, Bravo 4 blade, and the boat would run consistantly between 95 to 98 mph. Wish I never got rid of it.

with a 1.5 gear, I would try a 32. Mine stock with w 500efi and a 28 B1 would pull 5200rpm so I think with an extra 150 hp, you should be able to pull a 32.

I would try a 30 or 32. I bet you end up with a labbed 32 or stock 30. I have a friend with a quad rotor motor putting out over 1000hp in his his 25 foot daytona and his stock b1 handles it just fine. Its all about the drive habits and weight.

I have a 25' Daytona with a 572 NA motor 730hp and a Bravo XR spinning a 28p prop I see just under 100. I like to be able to ease it out of the hole. A big prop 30 + is going to be slow out of the hole but fast on the top end...
