SeaDoo Spark Rotax water pump gasket leaking & repair.

The OEM black gasket on the 2015/2016 SeaDoo Spark with the 60/90 horsepower engine was leaking after heat damage.
The original part number 420431680 has been superseded to 420431682, which is a green gasket and is .5 MM thicker.
It’s a simple replacement but you need an E8 torx socket to remove the plastic water pump, some lock tite to reinstall it and will need to remove your air intake box to make room inside the hull.
Thanks for watching the video on the replacement process!

How do you properly fill the cooling system afrerwards?

[@DaveMathews]

Fill it with the proper SeaDoo or aftermarket glycol, then run the engine which will suck the air out, turn on the hose to cool the exhaust. Turn the engine off and refill the small overflow coolant tank, then run again to get the water pump flowing to again remove air from the lines. Keep turning off and filling until it stays at the proper level for the tank. This only needed on run step for me.
