Fuel system moisture

I have a 1988 SN 351PCM. Does Correct Craft recommend or not recommend using "HEET" in the gas tank?
Thank you

Do you have a water problem? For winterizing I use marine Stabil in the gas.

Nautiquehunter , I use regular Stabil in my winterization process and often thought about using the marine grade Stabil as an option but passed on it due to the increase in cost. What are the pros of the marine grade vs regular Stabil?

Marine grade (blue) specifically "bonds" to water/condensation so it can safely burn off. I use both red and blue, but always use only blue a month before winterizing and top off fuel tank to reduce the area in tank that condensation can build up.

Great thanks for explaining
