So I have a 2004 Polaris LE 2100 jet boat and cant figure out my issue, boat starts only when you give it gas, then runs for almost exactly 10 mins then stops and wont start back up till it cools down, thought It was a fuel issue but now im told it may be a thermostat because one hose was hot and the other cold, so I pull her out to change the hot side thermostat and I let it run on the hose to see witch side heats up and nothing! Runs perfect on the hose for 20+ minutes?!? Does this tell me theres something stuck in the intake under the boat?
