omc overheating high rpm

Re: omc overheating high rpm

Problem Solved. Thanks again to all for your help you all saved me a lot of cash. I certainly appreciate all the input and of course the people responsible for the operation of this site.<br /><br />I pulled the exhaust riser (elbow) two of the four ports for water flow were completly plugged up with rust and crud. I didn't even try to clean it out. Went and purchased a new one and installed it ($130.00) Runs like new now. No overheating at all. <br /><br />Does the rust come from the exhaust manifold and inside the engine. Does it mean the next thing to go will be my exhaust manifold or engine. Is there anything I can do to prevent further problems like this? Is there anythng I can put in the engine to clean it out or would it just make things worse. <br /><br />Thanks again<br /><br />Jerry

Yes<br /><br />

Is there anything I can do to prevent further problems like this?

Salt-Away can slow it down, but nothing will completely eliminate the problem.

Thanks Don and all again-<br />I have been out of town a few day but wanted to make sure I responded again with a big thank you- as I said I have replaced the riser and all works good for now. I will also in the next few weeks save up $$$ asnd replace the manifold- this should give me a little extension on the life of an already aging engine. Then if the engine gives up on me I will already have good risers and minifolds.<br />Thanks again-<br />Jerry
