03 250 hpdi alarm question

[canes1]

Went out the other day boat was running great. came off plane to idle speed and after a couple of minutes the alarm went off. plenty of oil in res, still pissing water. boat would idle fine but seemed to hit a limiter at about 2000 rpm. idled back to ramp. oil res under cowling only about half full. now when i just turn the key the alarm sounds off. any ideas what this could be? Thanks

motor tank is low on oil. use the oil tank switch on the motor and fill up the tank.

What could be causing it to not fill? filter or pump maybe?

[rangerguy]

Filter or Sensor in the tank or pump.

mechanic said it was a trim sensor problem. if the motor is tilted too much it will not let oil to pump up to the motor res. and since the trim sensor was off it could not pump.
