For the life of the pwc gods,,,DONT install that rooster tail!..I was at the marina, doing a mobile repair,,,the Yamaha was on one of those floating pwc docks,,I made sure part of the pump was in the water for cooling,,,and after I started it,,the rooster tail wetted a passing boater,,,he was not pleased, but pissed.
Also, the rooster tail is not connected to the exit cooling line as I had thot,,,it's a hose that connects from inside the pump to that fitting!
