OVERHEAT

[samnpatty]

iv'e got a 90 hp johnson i'm tinkering with, wondering if the the temp warning should go off after 4-5 mins at idle on the garden hose . or should you be able to idle indefenatley ?

I would think that if you just had it in neutral it should not overheat. If you had it in gear it might be a different story.

It shouldn't overheat on a garden hose at all if you have plenty of water pressure, if it overheatsyou may have a blockage in the water passages or the water pump may be bad. Wretchin might chime in and tell you what to do, he knows his motors inside out.

Thanks for the kind words Doc!...

The engine should be able to run forever on the hose without overheating. It is easier for it because water is being forced in. There are several things that will sound the alarm. If you have a portable tank with the vent closed this will cause the alarm to go off. This puts the fuel system into a vacuum and triggers the alarm via a switch on the side of the engine, a bad water pump, bad thermostat, stuck poppet, freeze damage below #3 , the flush adapter not seated correctly, not enough water flow, bad temp switch, ect!!!!!!!!! Lots of possibilities. Is it a VRO engine???? What does it do when in the water?????
