i have a 99 spx seadoo i was out riding today and i was idleing to the dock after riding for a hour are so and it locked up i thought it was the motor so i began taking it out well i took the jetpump cone off and was going to take it out and notice the oil was real burnt in there i started massing around with it and seen that the engine turned freely then so i used the starter to turn it several times seemed fine, my question is did the jet pump bearing sieze up and lock the motor down are what thanks...
