Bill Blanton Posted December 29, 2020 Report Share Posted December 29, 2020 Because of the pandemic and some other issues, my 2004 HPX-V with 2010 Yamaha F90 has been sitting in the garage since February. I've taken it out a couple of time to run the engine, but the boat hasn't been on the water since then. The gas tank was filled with non-ethanol gas, plus some Gas-Shok fuel treatment, when I put it away. I added more Gas-Shok from time to time. The tank is aluminum, not fiberglass. My question is, what kind of problems am I going to face with gas left in the tank this long? I expect to get the boat on the water some time in the next couple of weeks, but, by then, it will be almost a year since the engine was operated at anything other than a fast idle, and it will probably take a couple of trips to run all the old gas out of the tank. Any ideas, advise, suggestions will be appreciated. Bill Quote Link to comment Share on other sites More sharing options...
