Boat is 2hr from home so I don't have S#
Was hopping to order it before I got their--maybe I will just get both.
It's blue striped motor if that helps--someone said 78-83 but who knows.
Even with the serial number they recommend going by the visual check. Either pump will bolt up to the engine and someone could have changed it.
But on the bright side, you can pick up the pair for under twenty bucks.
