I have 91 Yamaha 150TLRP Pro V overheat alarm goes off after 2 or 3 mins of running above 4500 rpm. Below 4500 rpm runs all day long. Replaced thermostats waterpump and checked poppet valve still goes off. Pisser pisses good and water is not hot when alarm goes off. Can put hands on heads when alarm goes off. Put boat in neutral when alarm goes off and a min or so the alarm goes off and can resume going
