87 150 Black Max XR2

I'm having problems with alarm at start up and low speed. Even had alarm go off when the motor was turning over after just launching, when it did start I had oil smoke. Motor pees and has oil in both tanks. If you put boat up on plane alarm goes away? Any ideas

Fast Beeps like 4 beeps a second continuously.

That's oil alarm. Could be a sensor faulty, or a bad alarm module.

There's a whole diagnostic chart in the factory manual. It's really not that hard to troubleshoot, just detailed and a little involved.

One thing. A noisy or low voltage power supply will set that alarm off. A flakey auxiliary contact in the key switch is prime suspect.

hope it helps
