I just missed a nice set of 24 pitch Hydros right here on the classifieds section. Emailed the guy,,,,,,,, gone. $450.00 for both!!!!!!!!!
Dammit, I wish I'd have seen those a little earlier.

I ran my 22 bravo 1's today and was not impressed with the results. Cruise rpm/mph was about the same as my 23 mirage + props. Hole shot was definitely better but top end was off a couple mph at similar rpm to the mirage +. I did not have a lot of time to play with trim settings but my first experience was so-so. I might have to go to 24 bravo 1's labbed.

Ran a set of 23 hydromotives today. Water about 1' chop and 1/2 tank of gas (80 gallons) ran 61-62mph at 4400-4450 rpm. Boat definitely felt like it was more out of the water that with the 23 mirage plus props. What would be suggested to get my rpm up to the 5000 range? What would I gain by just dropping a pitch or two? Lab finish?
Thanks

i've just bought a 311 sri, its has 29 four blade 17" props, and takes an hour to get its lazy gas guzzlin fat ass out the water and on to a plane.
Sounds good though, just that with all that noise the gathering crowds expect you to be goin fast than 10 mph for the first mile of your journey
sounds like 24's are the way to go.
i put the props on after the boat was shipped over, should i swap them port to starboard, will that make a difference?

Powerguy, I think each inch of pitch equals around 200 rpms or so.
CWUK if you swap the props port to starboard, vice versa, just remember forward is reverse and reverse is forward.

29 down to 24 is a massive jump in pitch!!! You'll be bouncing off the rev limiters. With the props I think you've got (spinnelli cleavers?), I'm not surprised it takes a long time to get on the plane. 24ish would probably be right for a pair of 454 magnums, but I can definately see a pair of superchargers there!

CHINE WALKER you can not just swap SSM props side to side you have to swap the entire drive!!!!! If you just swap props you will be running your trannies backwards. First find out what direction they are turning (in or out) and then get back to us. Also a exact measure of the X dimension would be good. Of course this is after you fix the gas issue!!!

Jon, you're right, I forgot he was running those drives, I just had "bravo's on the brain". LOL
Don't know if I've ever seen a boat actually take THAT long to get up on plane.
