its a 1992Maybe a year would be nice.
If this were my boat i would run it on a external tank of fresh fuel. If the problem disappeared then i would go after the fuel system.
If it is the fuel system meaning water and gunk in the tank i would clean the entire system.
I pumped all the fuel out of my onboard fuel tank when i got it.
You can do one of 2 things, pump the water out of the bottom, or all the fuel out and here is how.
If you just wish to pump just the water out of the bottom of the fuel, you will need to purchase a cheap electric fuel pump from any auto store dc powered.
You will also need about 15 foot of cheap fuel hose from the auto store and clamps to fit the fuel pump.
Install the hose on the fuel pump both ends and cut about five feet on the sucking side of the pump just look for the arrow on the pump.
Remove the fuel pickup tube it's the one where the fuel hose hooks to the tank a 90 degree angel fitting, it's a anti-siphon valve. Unscrew it.
Crank the bow of the boat all the way up, and stick the hose connected to the electric fuel pump 5 feet into the bottom and back of the tank.
Into a clear container pump the water out till you see clean fresh fuel and stop the pump.
Or into a large container pump all the fuel out.
Now check the valve by blowing thru it, check the screen thats its clear.
Install the valve and pickup tube your done.
Question do you have a fuel water separator on the boat, good to have.
If yes replace the element.
If you have a bell type fuel pump clean the filter in that.
There is a filter in the fitting that enters the carb.
And finally i would rebuild the carb. Click on the link.

Welcome. A couple things first. You really should have started a new thread specific to your issue. And second, I'm not a mechanic, I'm just another boat owner who prefers to do his own maintenance whenever possible.
You replaced your distributor. What distributor did you install? I'm asking that because I swapped my distributor with a Voyager EST type replacement, and not long after I started having backfire through the carb on acceleration and sluggishness at higher RPM. I found that the module inside the distributor was no longer providing the progressive timing advance that it should have. I then bought a cheap replacement module, and after a short period of time, it too was not advancing. After a lot of Googling, I found that people are having success with the AC Delco module, which would have been used in a genuine OEM Delco Voyager distributor. I've had no trouble since I replaced the module.
So, regardless of the distributor manufacturer, my advice is to check your progressive timing advance. I was getting only about 16 degrees of advance (as I recall) from 1800 RPM and up.
If you do have the Voyager EST type distributor, the AC Delco module part number I'm using is D1965A.
