I am new to this forum and have searched for a similar problem to no avail.

My 96 ts6m has the right side (if looking at the engine from the rear) exhaust overheating.

The left side exhaust is cool while the right side is getting very hot. To the point of smoking.

I have pulled the raw water pump lines and water is making up from the pump and out to either side of the exhaust manifold.

I pulled the Raw water pump and looked at the impeller through the hose holes and all the arms are there and it looks good.

It seems like there is an imbalance of pressure causing all the water to go into the left side manifold.

I even pulled off the right side exhaust riser, but I do not know what I am looking for.

Any thoughts?

I have not pulled the boat from the water yet so I cannot tell if water is making it out of the exhaust flappers.
