I have a 2008 Seadoo Challenger 230 with the twin 4-tec 1503 supercharged Rotax motors. My left motor continues to pop its thermostat housing off and drain my coolant. It is a simple push lock style plastic housing. Is this a common issue? I can not seem to locate one on-line anywhere other than an after market Riva-Racing one, that is different and I am not sure if I still need the factory one with it. Do these motors over pressurize or is it a possible thermostat housing issue. Any assistance would be greatly appreciated.
