Just an update for anyone that has similar issues in the future.
Pulled the fuel filter out of the bowl on the fuel pump and replaced it. Pulled the two inlet tubes off the carb and flushed them. Sprayed some carb cleaner in through the carb a couple of times.
Re installed everything and now the boat runs great again. Guessing there was some dirt in the lines somewhere. Hoping to run the fuel I have in the boat ASAP and start with a fresh tank for spring.
