97 seadoo challenger fouling plugs
Good evening, I have a 1997 seadoo challenger 787 that is continuously fouling out spark plugs. It is an oil foul. I have the oil system correctly working and have read there is a crank seal failure that occurs. Im sure this may be the culprit but is there any way to limit the oil flow into the crank area via a restrictor on that large oil line. I cut off the oil on the large line (not the one going to the pump) and my seadoo ran amazing, no fouling plugs. Is this safe to keep on, how much oil needs to go there? Really don't want to do an engine rebuild since this engine only has like 30 hrs on it as is. Thanks

Are you using quality 2 smoke oil???
I've seen a lot of people use the cheaper 2 smoke oil and foul plugs..

Run quality 2 smoke oil.
Many issues with cheap oil.
