i've been wrong before, but I thought the thermostat was located under the coupler that joins the 3 hoses and feeds the hose to the front of the engine. its not there. so i checked down inside the coupler, toward the distributor. nothing there either. not sure where else to look..
351W so EFI temp is not an issue. and no heater in the boat. I thought i read something about fuel efficiency being off when thermo isn't working properly.
Temp guage was going on the blink end of last season. I checked the impeller again and just decided not to worry about. I want to fix it before we start riding a bunch. Is my temp guage itself going bad? and do i need a t-stat?
