First thing I'd try is removing the thermostat. If that doesn't bring the temps down, we can suggest further diagnosis. I've seen cases where a load of crud collects just below the thermostat.

A clean fuel system is step 1 for any engine that hasn't run in a long while. This should be done BEFORE you even try to start it. This is true for a Model A, and Atomic 4, or a vintage Mercedes. ...

Those two cylinders (2 & 3) with low compression do suggest a head gasket problem. Although I suspect no change, I'd suggest you add a bit of oil to each cylinder and do the compression test again. ...

On the original manifolds, I think those holes were blind (ie: didn't go through into the water jacket). Aftermarket manifolds may be tapped through. Big issue as I see it is exposure of the...

I wouldn't worry about submerging the exhaust a bit. My Tartan 30 had the exhaust out the port side at the waterline, and would motor sail quite happily on stbd tack.

The hot pipes are on borrowed time after 7 years. Recommend you unwrap yours and see what's going on. Might just be a gasket, but I doubt it.

Personally, I think I'd leave it. What you want is a snug fit between the key and the shaft, and you have that. A little slop in the coupling is no biggie.

For the hot section, I'd wrap with a few turns of fiberglass tape. I'd cover that with sheet metal (soup can) held by a couple of hose clamps. If after the water injection, I'd use rubber hose.
