    sponsons or ride plate ?

    I have a 93 SL650 that is a little wobbly or unstable at top speed. I don't want to put to much money into a $800 jet ski but found a dealer that will install used polaris sponsons for $150 or I could by an ocean pro ride plate for $100. What one would you guys go with? I know sponsons are for cornering but do they do anything for stability.

    The sponsons help yes. The Op ride plate may be the way to go if you still want to maintain the ability to do crazy spin outs and such.

    I'm surprised you say it's unstable at speed. Normally they are squirrelly at low speeds and get better as speed increases.

    $150 for sponsons is ridiculous IMO. They do help, but you'll benefit from the plate more, it's cheaper, and can help with acceleration.

    Also you can get used sponsons for cheap, install them yourself (we have directions posted in the tech section) and have them both for around $150. OP plate and sponsons)

    PS: there's a guy selling a used OP plate in the classifieds. That can save you a few more $$$$

    You are right, it is ok at top speed but a little squirrelly at low speed. I will check out the classifieds and maybe do both. I have never riden a jet ski with sponsons so I dont know if it is more fun with sharp cornering or doing spin outs.

    I personally prefer the high speed hard turns you can make with the sponsons.

    Honestly, if you stick with less aggressive OEM sponsons, you'll still be able to do spin outs.

    I like SLT sponsons, they help reduce porpoising, and still allow playfullness.

    This ski doesn't go fast enough to need sponsons & to install them is nightmare with everything that has to be removed including the floatation foam. Go with a ride plate, this will help stability a bit & give you a little extra speed in the process & very easy to install.

    Done correctly sponsons are easy to install, just be careful and measure twice. No need to remove anything.

    Just doing the OP ride plate will fix what you are talking about. I would try that first and then if you want to tighten up the steering more, add the sponsons. When I had the OP plate on my 650 it made it a lot harder to spin out.
