I have a 1996 Formula 27 sr1 I have a bravo one 1.50 gear ratio I have a 468 with Grumpy Jenkins Merlin heads that have been worked it has an B&M 250 blower with 2 650 carbs I figured the motor should be around 650 hp what prop fo you'll think I would need I was figuring a 26 bravo I know I will have to baby the drive thanks

26 Bravo should be a good starting point.

Thanks that is what I was thinking does hydromotive fo decent on that boat or stay with a bravo one prop

I'd stick with a Bravo prop for more bow lift
