Runs cool and anything above 4500 rpm the alarm goes off and it goes into guardian. Brand new sea water assy. Checked water pressure sender and no trash in it.
Water pressure sender in sea water pump was bad. Confirmed by scaning, replaced sensor and problem solved if anyone else runs into this. Newer style 496 has the sensor at power steering cooler there must have been a reason for this or they wouldnt have moved it
