I have a 1999 23' Gulfstream....it sat for 3 months because of a family member's health issues ( they are fine now Thank God ) It ran fine before. I added 80 gallons of fresh fuel and sea foam so the tanks had about 120 gallons. Well when I took it out back in the first week of Oct it ran fine for about 15 minutes then it cut off and wouldn't restart. Got it back from the grady dealer and they said the gas went bad. I had it drained and they also changed so seals and cleaned the VST and the fuel pumps on the Yamaha 225 2 stroke. I had the tanks drained, cleaned etc. Cost about $900. I asked the Grady dealer what is better for storage over the winter. THey advised keep both tanks empty. The People from the Fuel Cleaners advised to fill the tanks and add fuel preserver Valve Tech. I'm confused.......what is the best thing to do ?
