When I try to use the factory quick connect to flush the motor, it does not circulate ( not Peeing ).
When the boat is in the water, everything pee's fine.
It appears that the water does not enter the engine...............is the fitting that the hose ges to a backflow valve or something ?
It appears that I have to take the cowling apart to get to it and I don't have a manual or schematic to see what I am getting into.
Any suggestions or reccommendations would be apprciated.
Thanks for your help,
Don Q
