I have a 1988 Mercury 150 XR4 Black Max. She runs perfectly, with one exception: The oil injection alarm starts intermittently beeping (beep - beep - beep) at exactly 3,000 RPM, and won't stop until the RPM's fall below 3,000. This alarm is driving me CRAZY! I've replaced the Alarm Module, Regulator, Pump Piston, and checked all tanks and caps and done about everything I can to fix this problem. I'm leaning toward the stator being bad on the high side, since the alarm starts at exactly 3,000 RPM. My DVA tester won't be here for 4 more days, so I'm at a loss. I'd hate to go drop $190 on a new stator, and the problem still exist. I might just lose it. Any suggestions? Thanks, AC.
