I had an interesting chat with Mille Lacs CO last weekend and asked him how much water stayed in the jet skis and jet boats after the engine is shut down and he said he had no idea. Does anyone here work around those machines and can say how much, if any, water stays inside the pump housings after the engine stops and the rig is removed from the water?
Jet drives self drain. What I want to know is how much water is left in the ballast tanks on wake boats. I had a guy telling me a few weeks ago his boat holds 4000lbs of water when they wake surf.
