Any other tips? Bad gas maybe? Should I tear apart the carburetor? Replace the ignition coil, distributor cap and/or cables?
I'm getting a bit out of my depth.... :-(
Your "depth is is fine. You are aware of possible problems.
Rather than jump back and forth between systems (fuel, ignition) let's start with one system and be sure it is correct before moving on to other possible problems.
Water in the gas can cause all sort of weird running problems. So try running from an auxiliary fuel tank directly to the carburetor and see if the rough running goes away. Then we will know if the (possible) fuel problem is related to the boat's part of the fuel system or the engine's part of the fuel system.
All of the above is in IMO only. There are other valid approaches to trouble shooting.
