Yup or maybe a vacuum leak, bad base gasket or a leak somewhere else.

Try dribbling gas down the carb throat with a small squeeze bottle and
see if it idles (fast).

You can listen for a vacuum leak with a piece of small hose. Hold one
end up to your ear and probe with the other. It helps to stick a ball
point pen barrel or other small tube on the probe end so you can
control it better..

I don't know if you have a four stroke or a two, but if it only happens
when it's hot, how about (4 stroke) if you have a valve that's
stretching and bottoms out on the bucket when it's hot?

They tighten up when they get hot... on a four stroke..

If it's a two stroke, Do a compression test or a leak down test, then
check the reeds??? Do two stroke boat engines have reed valves, I
suppose they must...

Just thinking out loud, something is happening when it gets hot, I am
thinking you are loosing compression when it's hot or some kind of mild
blow by that doesn't effect the engine at higher rpm based on the ratio
of leak, to mixture delivered to the cylinder...
