  If your Polaris boat engine overheats, several factors could be the cause. A clogged jet pump intake can lead to overheating, so clean the intake. If you are using non-recommended fuel or oil, replace it with recommended fluids. Sand or debris in the cooling system can also cause overheating; flush the cooling system. Inspect and clean the cooling system if it is plugged. Also, clean the orifice fitting if the exhaust pipe is clogged.

  If your Polaris boat engine backfires, several potential issues could be the cause. Start by inspecting, cleaning, and/or replacing the spark plugs if they produce a weak spark. If the spark plug gap is incorrect, set the gap to specifications or replace the plugs. Old or non-recommended fuel can also lead to backfiring, so replace it with fresh, recommended fuel. For incorrectly installed spark plug wires, broken valves, incorrect ignition timing, or mechanical failure, it's best to see your Polaris dealer.
