I think it is a late 80's model. Got this motor off a Monark bass type boat, everthing seemed to work fine running it with the cups while on this boat. Put the motor on a pontoon boat and hooked cups to it, started it and after running a few seconds alarm comes on, not a constant ring but a real fast beep beep. It is pumping water through exhaust and through the pisser at a good stream. While on the Monark it did have a pressure gage on the console that I did not transfer, and originally it was the oil injected but that was eliminated years ago. Any suggestions?
