I have a 06 250HPDI and this will be my first winter with it. In the past I have always fogged my engines but after some searches I am getting mixed opinions regarding the HPDI and most posts seem several years old. Is there a proven process that I should be doing? The boat will be stored for about 5 months. The boat has only had Non Ethanol fuel and Ring free added at every fuel up. Do I still need to add Stabil? Should I fog through intake or just cylinders? Fuel seperaor and filters now or in the spring? I plan on doing the lower unit as well. Anything else?
