hello all.. please no rude comments, I'm mechanically dysfunctional, have never owned any two stroke engine recreational vehicles!...I ran my 1990 Sea Doo Jet ski, (which I purchased a pair of w/trailer for $1800), they were marine mechanic owned, however, I ran them about two weeks..and subsequently ran one out of oil. It is oil injected so..separate oil tank, but no warning lights, etc..(in the 90's they expected you to check your own $hit) ...anyway, It still turns over, etc...I guess my question is #1, is there an oil safety shut off switch on these old jet ski's for idiots like me and #2, should I be ok after I dump some oil in it and get it back on the water (FYI, it had oil in it about two weeks ago and I"ve only used it about 3 times, if that helps)...would love some positive feedback!..thanks!
