252 ls
 

i have a 252 ls with a 454 mag. and bravo 3 the speed is a little slow 53 mph at 5000 with a set of 24 p props. would putting a bravo one on it with a mirage prop be a better set up then the bravo 3 for speed ? and if so how much faster would it be. thanks mike

Bravo 3 is for a better hole shot. Your top end would definitely be higher with a Bravo 1 with the right prop, but you won't get on plane as fast. As far as how much faster it will be.........I'm not too sure.

Your setup is nice with the bravo 3, but if you switch to a bravo 1 I would only think you would gain 3-4 mph at best. Just may .02

Holeshot with Bravo 1 isn't bad at all and the boat planes very easily, I don't know how much better it might be with a Bravo 3. I haven't really done any 'real' top speed testing, but seeing 63-64mph on GPS isn't uncommon with a couple of passengers and a quarter tank of gas. A difference of around 10mph with slightly less power and B3 sounds more than I'd expect, have you already checked that you're running on all cylinders (plugs, wires, rotor, distributor cap) ? How clean is the bottom?

What year 252 and what drive gear ratio?

I had a 98 252SS with 7.4efi and had 26P BIII and ran 56 GPS. Had great holeshot as we tubed and skied also with 8-10 people on board.

24P seems too low. I was at the upper end of the RPM but never over. I always had full fuel and 1/2 tank water and cleaned out head. kept lots of gear on boat and 2 coolers.

Best I could get WOT with me and my 5yr old
on board was 58 GPS still full fuel and 2 coolers as we would weekend on the boat.
