I have a 1990 Force 150HP, new to me this spring. Like others here when I tested the boat there was no tell tale coming out only smoke coming from the two holes that look like nostrals. I'm going to change both the impeller and thermostat. The thermostat I got from iboats mega mall 18-3553, the only one listed, is smaller and hotter than the one removed 143 degrees vs 130 and about the diameter of a quarter vs a half dollar. Will the 18-3553 work and is there a pee hole on the 150?
