I purchased my 1994 Donzi Classic 22 in October of 2010. It has a 454 magnum 365 horsepower (carb) engine. For a few reasons I was not able to get the boat in the water this year. When I bought the boat we took it for a run and with the boat still running we put Storage Seal through the system (ran 20 minutes or so on the return trip to the dock). We filled the tank afterwards with Shell 94, it took about 30 gallons to fill the tank so there was some gas in it already.

My question is can I keep the tank full and expect the boat to run in the spring of 2012? I am not sure how I would empty the tank or into what but I am looking for suggestions/advice on what to do with it.

As always any help would be appreciated.
