The alarm on it was a continuous beep also.
If it is overheat it won't let the RPMs go above around 1200.
Worth a check anywho's.

I figgered out how the Mercury oil injection system works, 35 miles offshore. If the cap on your big tank isn't screwed on tight, it will set off the alarm.
My Merc. 200 used engine case pressure to pressure up the big tank to push the oil into the small tank, which has the float switch in it.
I didn't have the big tank lid screwed on tight enuff.
