My 95 seadoo xp seemed to be running great for the first couple days i had it in the water this season. Now it still starts up fine but after a few minutes of riding it will just shut off for apparently no reason. It always starts right back up no problem but will keep cutting out and i have no idea why. Any suggestions or ideas would be greatly appreciated, I am missing out on a lot of great days on the river! Thanks!

I have similar problems, same ski, same year. Have you pulled the sparkplugs to see if they are fouling? It starts but does it sputter and cut out when throttling? what rpms can you reach? mine seems to top out in the 7000rpm range. (my plugs are wet fouling, mostly on the MAG side cylinder) pull the plugs and check their condition, although it will be a bit inaccurate unless you do that WOT lanyard kill method. theres info on this site how to run and how to shut down to give a better reading of what your plugs are actually doing. Assuming you can run it long enough before it dies on you. Check your basic primarys- compression, spark, fuel delivery,filter, lines, etc.. Ive even heard problems with the kill switch itself. You have to start eliminating potentials to find the problem. and it could be from quite a few things, trust me... ive been dealing with it all spring.
But yep, my xp will start, but eventually dies from wet fouled plug or plugs. im sure i have a leaking Rotary Valve seal or crank seal. when i first started working on it (got it from someone who let it sit all year long without winterizing) a lot of oil would exit out the exhaust from the leaking seals allowing oil into the motor. most of it is blown out now as it no longer shoots out the exhaust but i have yet to run it for more that 30 seconds at a time at WOT because i havent put it in the water yet.

I'm having problems with this same ski. Mine will start and sometimes rev up on its own and then I'll restart it and it will rev up alright and when I let off the throttle it will sputter and die. I put new plugs in and they hardly have any gas or oil on them. I am so confused. Any ideas guys?

How would unplugging that work? It doesn't affect gas flow does it? I premix my gas.
