"Helping my stepdad today on &
"Helping my stepdad today on '94 3.0 GM 4 cyl. mercruiser. I was worried about the gas, since my stepdad really can't remember when the last time all that gas was run out. He said he put sta-bil in it (he thinks). I smelled the gas tank, and could not detect the odor of varnish, so I put in a pint of Seafoam. Boat started right up, we idled it for about a 1/2 hour, he took short trip down canal. The temp. guage has barely moved, it's on 100 degrees. Plus, when I feel the big curved hose (about 2 1/2 or 3" in diameter) that goes from t-stat to water pump it is just slightly warm. 1)Even assuming we have a faulty gauge, shouldn't that big hose be hot once you run that engine for 15 minutes or longer? I was thinking maybe the t-stat was locked in the open position? All advice appreciated- have boat at dockside now, unsure what to do- don't know if we will hurt engine or not."
