Temperature sender shuts down our new Genie 150.
Background: total engine run time is 5 hours, Genie has, per temperature gauge, never yet reached normal run temperature of 190 to 215 F. Shut down occurs at 180-185F, as per gauge temperature reading. Oil pressure is at 40-45 psi at shut down. Lots of cooling water is coming from wet exhaust. Genie is in the stock sound enclosure and located in a well ventilated lazaret. The lazaret temperature climbs from 70 to 100 F by the time the Genie shuts down. Genie runs somoothly and does not strain unduly under alternator load.
1) Can I trust that the gauge temperature is correct? (And therefore I can comfortably jumper the high temp shut down on the run controller to ground to see if the run temperature goes up to 190-215 and stabilizes.)
2) Should I trust the shut-down temperature sender and assume that the temperature gauge reading is wrong? (That would assume that the Genie is really running too hot and not at the 180F I read on the gauge. )
3) What should I do next to resolve this high temperature issue?
Thanks for your advice
