Transom Flush On Gprxp
I Like The Fact That Seadoo Had The Flush In The Back Of The Hull. So Finding A Way To Dojust That On A Yami Wasnt All That Hard.
Basicly What I Came Up With Was While Installing My Pump I Noticed The Water Exit Hole Was Close To Fitting A 1/4 Npt Fitting. Went Tothe Local Hardware Store Picked Up A 1/4 Npt Tap With Bit And Drilled It Out To The Correct Size. Ran The Tap And Hooked My Flush Up.
Benifits Are No Leaky Fittings In The Hull While Flushing.
Your Now Flushing Your Cooling In Reverse.
Less Mess In The Hull.

You are also cutting your water dump size in half. Make sure to watch your cooling loop pressure.
Looks like a great idea. What about drilling that hole out, say up to a 3/8"NPT and use a larger fitting?

It connects to the large dump line from the engine (the only one you should have) to the factory dump fitting on the transom plate on the GPR.
