    Should I get a new prop?

    Since I'm replacing my wear ring I figured I may just go ahead and get a new impeller.

    Looks like a lot of people recommend the the Solas 13/19? Yet I see some people running different. What would you guys say for my ski? The only performance mods I'm running are D-plate, flame arrestors (no chokes), and upgraded PV couplings. I've also cut open the additional holes in the cowling but I'm not sure how much that actually does. I'm mostly concerned with top speed. Should I bite the bullet or stick with the stocker? Thanks in advance.

    EDIT: 2000 GP1200

    What ski? SUV, XLT, GPR? 1200, 1300? What year? New pump or older pump? I'm gonna guess GP1200R with stock pump...probably from the year 2000...13/19 if thats the case.

    Man I must have been tired when I posted that! No wonder I wasn't getting any responses. It's a 2000 GP1200.

    I know 13/19 is stock, that's what I have on mine. I replaced the wear ring with a plastic one, and installed a new impeller, and mine still has a lot of cavitation out of the hole. I think I need to install a pump seal kit next.

    So this is a 1200 non powervalve? Or is it a 1200R with powervalves?

    I mentioned in the OP that it had upgraded PV couplings. :P

    Ok, just confirming its a (66v) GP1200R...thats a big difference from a GP1200 (65u) If you still have the stock non HO pump, then in my opinion, the 13/19 is the prop for you. Make sure the pump shoe is sealed, especially in the back where the stock foam piece likes to blow out and cavitation shouldn't be a big issue.

    Yep, its a 66v. I've never had the pump apart, though I hope to do that to install a new wear ring tomorrow.

    While your at it check the grease in the bearings under the pump cone.

    Replaced damaged wear ring. I got it up to 64mph yesterday. Prop is a Solas Concord 13/19 which seems to be in line with what I should have. RPMs are 7100-7200 at WOT. The only issue is that one of the stator veins has a dime sized chip out of it on the leading edge (previous owner must have sucked in a big rock). Also the prop has some slight damage but no dings in the edges (just some roughness close to the edge). How much is that likely to affect my speed? I've filed down the chuck that was missing out of the stator vein and I intend to get that repaired or replaced asap.
