Timely overheating problem

As some of ytou may have followed my saga, I started posting when I thought that my boat was overheating. Then it wouldn;t start due to the starter. Well, the starter got fixed so I took it on the river today to see if the overheating problem was just my imagination. Well, for the first 30 minutes I thought that there is no overheating. The boat ran smooth, new prop was making a difference, the temp was right on 175 (middle of my temp gauge). <br /><br />Right when me and my buddy decided to head back to the ramp, the engine all of a sudden hit 200 degrees and kept goign up. I turned the engine off and opened the back and the motor was steaming a bit. It deffiently was overheating. <br /><br />Well, could this be the tempermostat that may not function properly after a while? Could it be the impeller? Could it be as somebody said earlier that shavings were stuck in the engine and were showing up after 30-45 min of running? It has been twice now when the boat is running great for 30 minutes and then it it goes crazy and stopps cooling. <br /><br />Suggestions? <br /><br />p.s. paddling for 45 min at 90 degrees temperature is no fun.<br /><br />Thanks.

Re: Timely overheating problem

A few more details as to what you are working with would help. You make reference to a past post but give no link to it. All that being said, your motor should not 'steam' at 200 deg. unless you have a leak somewhere.
