I have a unit that runs very well but lately, it won't troll at idle, it just gets rough and dies. I changed fuel, use a fuel stabilizer nad the indise is still very clean and ship shape.<br /><br />I noticed today that the water coming out of the pee hole is as cold as the water. Could a bad thermostat cause the rough idle condition? I run in salt water and haven't replaced it since I bought new.<br /><br />Help!<br /><br />Like I said, this is a very new problem.

Resetter,<br /><br />The telltale water could be a sign. The better test is to touch the cylinder head (both cylinders) and check the temp. The head should be warm and allow you to hold your hand on it for a few seconds.<br /><br />Both cylinders should feel the same.
