I have purchased a Jet Drive unit for a boat I am building, and of course it didn't come with any directions. There is a connection for a cooling water supply from the outlet nozzle mounted on the transom after the prop which I assumed was the high pressure supply for the motor cooling coil and ESC as needed. The question I have is about the second hose connection located between the motor and prop which appears to feed a water supply to the prop shaft internally between the two bearings/bushings. What is its purpose, and how is it plumbed? Any help would be greatly appreciated.
