i have a 97 htm 24 cat. 454mag with procharger, bravo 1 outdrive. prop on it wont let it get on plane and just blows out. i need some advice on whether or not to get a 4 or 5 blade prop and what pitch would be best.....any help would be appreciated.
thanks

What is the hp of the motor and what gear ratio is the drive.You need to run a 4 blade, if your ratio is 1.50 then a 28 or a 30 pitch.If ratio is 1.36 the a 26 pitch.

just bought the boat from auction....dont know the exact hp but a 454 mag has 385hp, so add the procharger and it should be around 500-550. dont know the gear ratio etiher but its a bravo 1, i assume its a 1.36

I would assume its a 1.5 gear. 28P probably. Call Brett at BBlades, he can tell you exactly what you need, and pretty much tell u how fast your boat will be!!! HE'S GREAT.

Pro charger adds 165HP to a stock 385HP mag? +2 on the 1.50 Bravo and should check the X height. He might need to get some more prop in the water if it's always blowing out? Some days I really have to feather the sticks to get the props to bite.

thanks for the replys...i borrowed a 4 blade 29p prop from a buddy of mine...im gonna try it out this week and see how it does before i go and purchase one of my own. also my outdrive has a bravo 1 upper and a xr lower.

finally got to test out the boat again today....well i could get going a little faster but once it tried to get on plane it would blow out and try to catch, blow out and try to catch again. i ran a shooter 4 blade 29 pitch.....im at a loss for words...dont know what to do next. any suggestions??

Im running approx. 600hp on a 26' cat I found a bravo 1 4 blade 28p worked best for all around performance got on plane a lot better Dont go full throttle out of the hole you will blowout everytime(and blow your drive) I have to feather the throttle a little to get on plane you just have to get used to it

Stock bravo 1 4 blade 30 0r labed 32 works for my sr24. Never had an issue getting on plane.
