Drain it out. All of it.
After that.
I’d put a couple cans of seafoam and five gallons of gas and drive it around to mix it up. Drain again.
For sure put a spin on fuel filter and fill the tank with fresh gas, and promise your boat you’ll never neglect it again.

Pat summed it up pretty well. Do not run the motor until you resolve the issue. . Is the tank easily removable or not?

Just take the motor fitting off the fuel hose. It’ll siphon out when you pump the bulb.

this works great, just have enough jugs for the gas you are taking out.

Yamaha motorcycle shops used to sell a chemical that was designed to dissolve stale fuel varnish (the real name for it).
I don't remember the exact part number for the jug but it was something like carb-ur-ator cleaner.
Not sure if it's still in production but it's the only chem that worked 100% of the time.
It could be mixed with water OR gasoline for a super hot version.
Designed to clean carbs on year old (or more from warehouse storage) bikes still in the crate, but worked fantastic to clean fuel tanks and carb parts once torn down.
Idea was to just add to gas empty tank and open carb drain screws until the treatment filled the float bowls, then let it soak for a while and drain.
Carb pilot jets have tiny openings and clog easily and they did have limited success, turned out the tiny jets had to be removed and the holes cleaned with piano wire, otherwise the varnish was too hard to move out.
In any case, NEVER run an engine of any kind on fuel that has any varnish left at all, none.
I had a customer (retired auto tech here) who ran his car after adding fresh gas to the tank that had varnish and it stuck every valve in the head.
Bad for him, good for me, cost him over a grand to fix.
