I have a 1989 Evinrude 88 SPL ... it was running a little hot when running wide open last fall so had outboard mechanic install new thermostats ... the boat hasn't run in the water since they were installed only with ear muff at the shop for about 15 minutes and it ran fine. Now after sitting all winter after running with ear muffs on for only a couple of minutes the overheat alarm goes off .... the water is coming out of the Pee Hole fine and the hole at the bottom. One guy told me it sounded like the thermostats were stuck .... I know NOTHING about mechanics and don't have a bunch of money to put it in the shop. Can anyone tell me how to tell if it is the thermostats stuck or what to do if that is the case. I tried tapping lightly on the thermostat housing while running but didn't help. Thanks .... Garry-
