I have a 2009 seadoo challenger 230 SE 510hp. I have a problem with the heat sensor alarm going off on 1 engine. I changed the heat sensors on both sides and it still goes off. It seems to go off when I get on it. If I feel the motor one is definetly hotter than the other. I think the intake hose may be restricted but I dont know which one it is. Can anyone help?
