" I have a 2000 model 150 Salt
" I have a 2000 model 150 Saltwater mercury outboard that sets off the high temp alarm at random intervals. Once the alarm sounds, engine off and restart, I may go 20 miles without another alarm. Took to dealer and they replaced t'stats and said this should do it. First run out within 2 miles of launch point, alarm goes off again. Trolled afterwards for 4 hours (no problem). The water stream from the pee hole is strong and no water inlet blockage. Have flushed engine and even removed hoses and run to check for blockage. Dealer said water pump should be ok and water temp test at 1500 rpm was 150 degrees. Any suggestions? "
