    Super Jet Footholds for Stock SN

    Just looking for suggestions on an affordable pair of footholds for a SN without much brap. I won't be doing barrel rolls or backies, so don't need the high dollar models. Just planning on re-turfing before spring and want to go ahead and take a stab at installing some holds for added fun on the...

    Surfriding St. Pete Beach Riding?

    I just found out I'll be heading to St. Pete Beach in August for a wedding. I'll be staying at the Dolphin Beach Resort (4900 Gulf Blvd). I've been told there is a public beach right next to the resort (4700 Gulf Blvd). I'm wondering if it would be worth towing the skis down. Can anyone help...

    Super Jet Won't Start When Hot

    650 SJ w/ Coffman Sizzler starts on the first hit when cold, but if it dies it won't restart for anything. Cranks and cranks with no fire at all. Usually you have to let it sit for an hour or more before it will restart. Just looking for some possible reasons this is happening. Thanks in...

    Super Jet Midshaft Leak Test?

    I replaced my driveshaft before last season and the ski has been taking on water at a pretty rapid pace ever since. Used to be able to let it sit in the water all day and it was fine. When I put the driveshaft in, I had to pound on it pretty good to get it to go in (insert 'that's what she...

    Strange Electrical Problem

    My buddies ski (650 sj) died on us the other day out in the water after he dumped it and got quite a bit of water in it. We tried forever to get it restarted. When I let my finger off the start button it kept on cranking away. To the point where it ran the battery completely dead. I...

    Fouling Plugs - Please Help

    90sj w/ a stock 650 (besides MSD coil & wires). Keep fouling the plug for the front cylinder only. I have been running 40:1 mix (a little cautious I know) and have stabilizer in it still from the winter. I would assume if it was a fuel issue, both plugs would be fouling instead of just the...

    Another Driveshaft Question

    Long story short, I am replacing a driveshaft on my 90 sj. I am trying to re-use my existing skat trak prop that is still in really good shape. The first thread is screwed up on the prop so I want to buy a tap to clean it up. It will be a 20mm diameter tap, but what is the thread count that I...

    Stripped a Driveshaft...

    Last Saturday I put my 650 sj in at the ramp, rode easily around a rock wall to beach it and think I picked something up in the intake. Immediately got off and stuck my hand in both sides of the pump to see what it was. Didn't come up with anything. Started it back up, it idled fine and got...

    Making a cooler out of a hull

    So I recently picked up an old 300sx that I am gutting and turning into a cooler. I know people have done this before, so I would love to see some pics and just hear general ideas about how this thing could take shape. We are determining if we want the pole and hood to open up like usual or to...

    What is really "needed"?

    I'm going down the checklist of what I should probably do to my 650 sj this winter. I'm planning on putting some new gaskets on it. For sure a head gasket, but what else is really "needed". I have no idea if any of them have been replaced in the past. I've only owned the ski for a year. I'm sure...

    Do you need UMI turnplate for 0 degree bars?

    Well the title pretty much says it all. I really want to put 0 degree bars on my SN. Do I need to buy a UMI turnplate for UMI bars to work, or will the bars slide in with my stock plate? Is the UMI plate a "quicksteer"? Thanks!

    Looking for this thread. Any help?

    I saw a thread awhile back that talked about how the front lip where the hood seal sits on a sn sj will sometimes bow down over time, preventing a proper seal. It said something about filling the "valley" with epoxy to get it level. I was wondering if anyone knows where that thread is, or has...

    Longest Ride On a Standup

    This is primarily just my curiosity, but maybe it will spark some conversation. What's the longest you have ridden your standup? I'm talking point A to point B distance. I know at Lake of the Ozarks in MO it's easy to measure by mile marker. Just seeing if anyone has ever tried a long trip. Did...
