CV-23 Prop Help...
Hot Carl:
Christmas is upon us and I figure I've been good enough this year to treat myself to a new prop. I'm not incredibly well-versed in the area, so I'd really appreciate your suggestions. The prop will be pushing a CV-23 with a Mercruiser 260...the prop that came with the boat is a 17p (yes, 17) stainless Michigan Wheel, and although it's great out of the hole my revs are obviously on the high side (I've briefly pushed it to 5,200+ a couple times). The previous owner claimed he used to put a 19p on it for more speed, but it seems a 21 would be a better choice. Any thoughts? I've been told the Laser II's work well on these mercruiser i/o's, but I haven't been able to find much info on the ol' interweb regarding these hulls and prop choice. I'm just trying to get the revs down a bit and, like most of us, more speed ;D
I'm also looking for a pair of center rise manifolds, so if anyone has some laying around or knows of some for sale in the TC metro area please let me know!!
Thanks,
Alex

Might be best to do engine mods first then try some of the local guys props before buying one.

Proping out a boat can be a Trying effort to say the least, if you want to get maximum performance, and it also makes a difference in what ya want to achieve .. my boat is about the same hull, basically, but it's some what lighter, I try'd 16 or 17 props before I got one to work with. Here's the scoop .. Mercruiser has done a Lot of testing to get maximum performance out of their props, no dought about that, but there are several props that are out performing the Mercury/Mercuriser designs and are more effecient for individual needs. I prefer the three blade PowerTech prop, or the Enertia props for speed and performance, but for power and pulling a 4 blade works better, just not as fast, and takes a little more HP to twist them.
I'd think a 14 1/4 X 19 prop would be a good all around prop for your boat, but if you was not going to carry a load of people, or pull a tube, a 13 3/4 X 21 or maybe a 14 1/4 X 21 would get you a little more speed. the PowerTech props have a lot of "lift" built into them as the come, as does the Enertia, but a good prop shop can put more "bow lift" in a prop for you, so you can lift the bow up and get a little more speed that way also.
CVX Fever:
Another prop I'd consider because your boat is bigger and heavier than most Carlsons, is a Mirage. Whether through a dealer, like Supreme Marine, or guys in the club, I'd experiment with a number of different props before buying something. Don't be like me and spend good money on a brand new Mercruy Enertia only to find out it's too much prop for your boat!
You could also go on the national site and see what other CV23 owners are running. Your the only CV23 onwer I can think of that regularly visits this site.

Alex I have a 23pitch Mirage you could try, Probally to much for your boat.
I ran it on my boat before and after mods
switched over to a laserII worked out much better.
I agree with Red that there are more props out than just the Merc props
Would not run out and buy, beg, borrow or rent to find out what will work
Good luck Jeff
