Just replaced both the Tstats on a new to me 130 evinrude, after solving h20 pump probs one of the heads is heating up. I pulled the tstat and the head colled way down. Seems like the tstat is bad right?<br /><br />Anyway it is a new tsat so it seems like it should not be bad, anything else I should check?<br /><br />The pin that fits into the top end of the tstat is lose and can be pulled out, does this mean it is bunk?<br /><br />Thanks<br />tony
