Got my prop from Hydromotive this past week and ran it this past weekend. Didn't have a chance to get real numbers but so far it seems to work very well.
It's a QIV 24p.
Great hole shot, no cavitation, got on plan quicker, mid range pull is awesome, and it picked up 3mph on GPS(65mph).
RPM still seemed low (about 4600) but I ran out of space to play with trim where I was. Will play this weekend and post.

ps
Still got smoked buy a 38' cig, but I don't think that will ever change.:rolleyes: :rolleyes: :rolleyes:

Hi all I bought a 89 251 convincor about a mounth ago, it has a 509 in it with a dart intake 1050 dom healthy cam nice set of headers. runs excelent. I have some of the problems you guys are talking about ,loose steering,prop cavitates at take off and almost allways at 3500rpm. I also think it needs bigger tabs. I havent run it at full speed yet (need to fix steering first)but it pulls hard at 60mph. Hey All trimed up the intake is stamped valako if you could get me any info on my motor that would be great.If they remember it. The boat is black teal and gray and said checkthis on the side of it. Any info on how make this boat drive rocksolid be great.

What prop are you running???
Call hydromotive, they'll get you going in the right direction.

High Roller, you may want to try a Hydromotive QIV, if you are happy with your rpm with the 3 blade, then drop a few inches of pitch and it will drastically improve your ride. Also install hydraulic steering you will be a lot safer. Good luck and lat us all know how you are making out. Dave

Thanks for the info. I'm trying to make up my mind on how to fix the steering,so far hydraulic looks to be the way to go. I read over all the posts great info! i'd like to try the 4 blade. I'll let you all know what I do and how it works.

Highroller
I can stop over there and see if they remember.
My friend is having the same problem with his steering he is going to go with dual ram by imco. That might be what you need. Where do you boat.
