Overheat is nothing more than not enough water making it thru the engine consistently.
Whats blocking it from running thru freely is the mystery here.
I guess if you wanted to:
You could bypass the intake water line by removing it from the thruhull or disconnecting it from the water pump input. Then connect up a bypass hose and somehow extend the hose so you could drop it in a bucket or toss the end overboard to pickup water.
This would test if the thruhull is partially blocked and/or if the intake tube is good. Good flow by getting water another way, is a clue.
You could also bypass the exhaust output line and toss that bypass hose overboard or in the cockpit. If you still get good flow at higher rpm with the exhaust bypass, then the exhaust hose is not the issue.
Process of elimination.
