Like title says 1987 Erude XP150 alarm at WOT only, this only occurs when I run WOT, either after on plane or from dead stop. I can run 40-45 for 15 miles at a time and no alarms, but if I push it to WOT buzzer sounds, seems to be solid buzzer , If I back off back to 35-40 the buzzer goes off.
Replaced Thermo Stats and water pump couple months ago. VRO pump disconnected by service guy b4 i bought this boat.
Ive seen a few posts on other boards that mention fuel restriction issues, and someone mentioned a vacuum sensor ? I couldn't find anything in manual about a vacuum sensor.. I need someone to go with me to monitor bulb to see if its getting flat at WOT. so until I can get some one to go .. I don't know about that one. someone else mention anti back flow in tank. or how to test some of the above suggestions given to me previously
Any suggestions I haven't tried or done already?
Thanx , Sean

That alarm if solid tone is over heating,Beeping is oil loss?Sound like your Eng needs a low water pick up.or lower it down 1 bolt hole on the transom.It sucking air.if you keep running you will burn the top cylinders up.Install 2 temp gauges on the top 2 cyc.

a loud steady buzzer indicates either no oil or over heat.Since that the VRO has been disconnected then your alarm is for over heating,and then only at WOT.There is only one cause and that is that air is getting into the cooling circuit and that can happen if your engine is trimmed to high and or the engine is mounted too high on the transom.Try again with out going to max trim, but still at WOT.You can easily check to see if the engine is mounted too high,pull the boat out of the water on a trailer,then with the motor in the full down position check to that the anti ventilation plate is at least 1" below the bottom of the boat.At this time you can also check that the trim limit switch is adjusted properly,it could be allowing the engine too come up too far at max trim.

RPM of the engine is more important. OMC engines should run at around 5200-5800 rpm's. Check your tachometer and see what the rpm's are at. If you are exceeding the 5800 limit you could be over revving your engine which will shorten the life of it pretty quickly.

port side of engine by starter...vacuum pod. shouldn't cause an alarm though. definitely sounds like a heat alarm though. maybe you have a poppet or flow-control issue.
