How to Replace the Water Pump on a Sea Doo Jet Ski

If taken care of properly, the Sea-Doo personal water craft is not prone to operational problems. One important part of Sea-Doo maintenance is servicing the water pump regularly. This part pumps water throughout the engine of the Sea-Doo, which in turn, keeps it from overheating. The pump consists of an impeller and gaskets, which need to be changed at least once a season if the Sea-Doo is used regularly.
