I would not panic yet. One of my first boats overheated one day as I left
the harbor heading for England.
Temp rose to 260 degrees. I putt-putted back to the slip and JiminFl came
to the rescue. He determined that my old manifolds were shot and replaced
them with new ones of an updated design. The boat ran fine after that.
Different engine, I realize (350 Chevy), but the first step would be to
replace the impellor and see how it goes.
You might get lucky.

Does that engine have aluminum or cast iron heads?
Aluminum heads are not as tolerant to overheats as the cast iron.
