Just bought a 03 xp di

[greg111]

Hey everyone, so i picked up my first jetski last week. Its a 2003 Seadoo xp di with 110hours on it. Im a newbie willing to learn, so school me please. I bought ngk spark plugs last night, but i still want to do more. The previous owner told me that it has gas from last year( not sure if i should drain it or just add new gas to it)? Then he told me to add some oil, i opened the cap and i looked at the oil( it looks like the color of yoohoo)not sure how 2cyl oil should look. I heard 2cyl oil doesn't get changed, just added. I think i would want to drain it because the color of it scares me. On to my next question, which kind of oil should i use for my ski( i seen seadoo but its pricey).

Please help out thanks guys!

you should only use bombardier full synthetic xps oil, imo. the DI motors are very sensitive to oil since they do so well on gas, and yes, it's brown colored but I wouldn't call it yoohoo colored. others may suggest a different full synthetic PWC oil which may work but the bomby oil is proven on the DIs, that is for sure.

you should be fine just to top off the gas with fresh gas if it is just from last fall and someone winterized it properly with sta-bil.

My compression is 110 psi in both cylinders. It was my first time doing it, hopefully my numbers are accurate. Yeah my oil looks like light brown similar to yoohoo lol, the previous owner told me he used the seadoo oil( what is the color supposed to be)? Should i drain it from the oil tank and my put some new oil in? I need help locating the the oil drain, or should i siphon the old oil. My last question how much oil does the tank hold. Thanks.

110 is not good so I hope you didn't do it right, you should crank it for 10 seconds straight with the throttle held wide open till the gauge stops climbing. you should retest because that low of compression will need immediate attention and won't run well on the water.

there's no oil drain, 2 strokes mix oil into the fuel and burn it so need to ever drain. Buy some new full synthetic seadoo XPS 2 stroke oil and if it looks the same that is currently in your tank, color and consistency, then you don't have to drain it, just add to it and use it.
