I have twin 717 motors. The starboard engine and tuned pipe, engine and manifold is hot when running water through the starboard engine. the port engine is nice and cool when running water through it. Purchased and replaced tuned pipe and problem still exists. Swapped tuned pipes with good engine and the problem stays with the starboard engine. I have the engine cooling system diagram and would like to troubleshoot it with someone knows what possible could go wrong.
Please advise.
Thanks
