Every time you add a blade the back of the boat will come up higher. I say. Call hydro.. - stocking fee , you should get a refund. Sounds like your boat worked well with the Bravo 4 bl ( which is not uncomon because that is what your boat was designed for) Now is a good time to sell props in the classifieds. Not at the end of,the season. You should be able to get close to what you have in them on the oso classifieds. I say 32 B 1's. BBlades.com will rent you a set for 25 bucks a piece. If you like them you can just buy them off him. Hope this helps. Chad

i had a 97 38 fever great rough water boat.it needed at least 5.5 trim to fly.3.5 or 4 below bottom is still deep in the water in fact when i put - 2 shorties on my 47 i gained nothing .hydromotive Q 4 is what that boat came with and they work great on early model fountains.

man i called hydro and they said because of what i did with the drive height my prop slip was way high so i need 5blades. i had 30 B1s and hit about 83-84 but was revving 57-5800 (a little to high on the revs) so i spent like 2200 on these props for nothing. i love boating!!lol
with bravo style props. My boat ran 86mph with 600 hp aside, 92mph with T 700s & 105 with T850.

I have a 97 38' Fever with XR uppers and Imco -2" shorties, for power it has Mercruiser HP500s with Dart Pro1 CNC heads, cam, Stainless Marine Gen 3 exhaust and carbureted Whipple 2.3L Superchargers I figure I'm making about 700-725hp at 6lbs boost. With BBlades 32p Bravo1 props it ran 97.4 mph at 5800rpm with 2 people and about 150 gal fuel with minimal trim about 4 on the indicator.
It is possible the motors are putting out a bit more but not much given the small SC but i live in the Cayman Islands and dont have access to a dyno. I am reluctant to say this because some people might doubt me but the truth is that wasn't top speed, it was in a poker run and I was holding back a small pinch or throttle and she definitely runs faster with more trim but I was holding back till later, unfortunately engine mashed up before I got to go for broke.
