Anyone used a Bravo 1 prop on a 251 Convincor? I have a Hydromotive QIV on there now that runs great but it seems a little bow heavy at higher speeds. It takes a lot of trim, past the drive limit switch, to achieve decent speeds on flat water. I read the Hydromotive is good for boats have natural bow lift like the old Convincors, but maybe it's the all junk on board for over night trips + the AC unit mounted mid ship.

Stock bravo 1's have been the best all around prop I have seen for a Convincor. I would try on your boat the 24p bravo A labbed one will blow out and rev during crusing speeds and is only good for top end, and is useless everywhere else. Checkmates have no problem carring the bow so a bow lifting prop is no good.

my mate has a problem carring the bow. it rides very wet. i put a 23 mar plus on it and it road ok, but blew the prop out, labed and un labbed.
my 4 blades run much better, but i think with the rake right and labbed my 24 should be right where i need to be. we'll see wn brett finishes up the one i sent him yesterday

Understand what you are saying but you also state that if you trim it. It will come up and thats a Checkmate. Theirs no need for a bow lifting prop if your trim will lift the boat. Thats what trim is for.
Let us know the true stats of the prop. I recomended NO 3 blades for any Deep V Checkmate

Obviously you have never been in a ZT hull. As stated here they ride very wet with alot of hull in the water. The recipe that BBlades has been using for Noyzee's boat and my old boat has to do a semi agresive lab and then add more cup back in, works great! With that being said Convincors and ZT are a totally different animals, for my experience Convincors traditional have no problem keeping the bow high!

sweet. was your 496 a mag or ho?
Purple, even trimmed way up, past the 1/2 way mark on the trim gauge it still rides very wet. i think brett was on the right path with the 26p but my boat just didnt have the power to turn it. i think if he does that to the 24 i sent him, i will be in good shape.
Magic, your right on. i can trim my boat up till i have a roost going, the boat goes no faster or slower after a point, and the r's dont change. the 26 bblades did for me seemed to work the best so far for carring the boat (still a little to wet) but with the lower HP mag i couldnt spin the prop past the 4400-4600 range. like i said, i tested the 24 b1 on my boat tuesday and it seemed to be pretty good but would only run about 4600-4700 rpm trimmed way up, so im guessing if brett labs it up nice, and throws what he needs to for the bow lift, im thinking i will be in good shape!!
i 2nd day aird him the prop, so he should have it today
