I know you said that your not overheating but did you pull that raw water line and check for full flow?

I guess you mean the line that exits the bottom of the heat exchange. - Yep - besides its a new exchanger. I mean at 3800 rpm you have got a lot of exhaust velocity going on. Ill keep a watch on it.

Frosty - yes back pressure is important - same muffler since 86 I guess. How would I know if it the right size?

If the water going to the exhaust elbow is too hot to touch (over 140F) it is plugging the heat exchanger and other areas with salt from the heat.

The burnt rubber smell might be a gasket getting roasted

Out sunday for a long run - not so bad now - I expect the time I had blockage and it got so hot - seems even less - Max rpm stayed cool enough - manifold was hot, hot to touch. No burny.

dealing with the prop pitch - rpm issues.
