I've got a ton of seadoo parts laying around so I figured it would be fun to try and build a ski with them. The core of this project came from an early 90s 3 seater (I think a 93 GTX) that was completely stripped and packed away in a huge box. It was included in a package deal for free as "a box...

I'm looking for a 155mm 2 stroke plastic pump in good condition. Prop is not a necessity

I finally got around to tearing down the SPX last night. The PTO piston looks like it ran lean and caused damage right where the top ring meets. I didn't see any debris in bottom end but it obviously went somewhere. Think I can get away without splitting the cases?? I really didn't want to...

I'm looking for two front bumpers, one for a 95 XP and the other for a 96 XP. PM me or reply here with an asking price and preferably a picture. Thanks!

I'm trying to figure out an electrical issue on a 96XP that I recently picked up. The MPEM gives one long beep when you put the key on. In diagnostic mode it gives two short beeps. I tried swapping the post with a known good one but still just one long beep. Since the ski is new to me I figured...

I picked up this umi setup last winter with the intent on rewelding it but never got around to it. Now I'm starting to think I should just sell it and buy one in better condition. As you can see the threads are stripped, its broken near one of the main orings, and the support plate on the stem...

What do you think caused these straight lines on my 97 SPX rotary valve cover? They are just deep enough to catch your nail. I'm chasing an air leak and took off the RV cover to check everything.

Went to the lake yesterday and burned a tank of gas through the 96xp and had a great day. I loaded everything up and I went to start it on the trailer to get water out of the exhaust and nothing. No lights from gauge, beeps or anything. I figured it was the key or post so I kept trying different...

I have an issue with my ski that I can't seem to figure out. It idles fine but it won't break 2-2.5k rpms. The motor just bogs and shakes violently. I first encountered this issue after breaking my front motor mount and ovaling out the carbon seal. Replaced the carbon seal and I was good for a...

I recently picked up a 97 SPX that has been sitting for the past 5 years or so. Its in excellent condition cosmetically and has an even 152psi in each cyclinder. I pulled the hours and it only has 47 on it! I decided to keep it so I rebuilt the entire fuel and oil system along with all the...

I'm trying to hook up the multi gauge on my X4 but the wire colors don't match up. I took it apart last fall so I can't remember how it was before. The 6 pin connector has a purple, black, 2 pink and 2 blue wires. The pink and blues match up but there's no match for the purp and black wires. I...

Hey everyone, I've been following the 2-stroke ski forum for a while now and I noticed we seem to get a lot of the same questions over and over. I was thinking we should make a sticky with some of the solutions to our common problems and maybe add a questionnaire for those making new posts. I...

I'm finally getting around to rebuilding the 717 and I cannot for the life of me get the circlips installed. I've broken both thumb nails and tried working it in with a flat head with no luck. I searched around and people said to put the open end first at 6oclock and work your way up the sides...

Just like the title says, would you trust a Harbor Freight clicker torque wrench for building an engine? My buddy has a 657x he's trying to put a top end on and I told him I wouldn't trust the HF wrench. Afterwards I looked at reviews on the net and people seemed to say they are pretty accurate...

When I pulled the pump off my 96 XP, it ripped off all of the black sealant around the two center bailer hoses. What do I reseal them with? I ordered the neoprene pump seal but I didnt know about the black sealant until I ripped the pump off.

So this was originally supposed to be a top end only rebuild but I managed to drop a roller pin into the bottom end so I'm forced to split the bottom apart. Will I have to replace everything in the bottom end or can I get away with just seals if the bearings sound ok? If I have to replace...

Like the title says, I'm looking for a set of flame arrestors and adapters for my 96 XP. PM or post here with what you have and an asking price. Thanks

skip to page 2 I started the overhaul on my 96 SPX I picked up for dirt cheap last fall and I have a few questions about it... 1) This is my first top end rebuild and when I pulled the pistons off the rods about 30 pins fell out and dropped down! Thank god I stuffed the bottom end with paper...
