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.

Items you will need

  • Screwdriver

  • Socket set

  • Impeller tool

  • Water pump kit

Step 1

Access the water pump and use a screwdriver to remove all the outflow hoses attached to the pump.

Step 2

Use a screwdriver to remove the screws holding the water pump housing in place. Set them aside and lift the pump housing out.

Step 3

Use the impeller tool to remove the impeller nut from the pump housing. The threads are left-handed threads, so the impeller nut has to be turned to the right for removal and to the left for installation.

Step 4

Remove the old impeller, and place the new impeller from the water pump kit into the pump housing. Place a fresh gasket from the water pump kit onto the seal of the pump housing and then replace the propeller nut by turning it left with the impeller tool.

Step 5

Set the pump housing back in place and replace the mounting screws with the screwdriver.

Step 6

Use the screwdriver to replace the outflow hoses.
