Ok my previous boat was a G3 with a little 40 hp 2 stroke, when I winterized it I just had to take 4 bolts out to take the black plastic cover over the intake off, so I could spray fogging oil into the carberateur while the engine was running to winterize the engine. My new boat has a 115 hp, and I'm not sure how to take the intake cover off, it looks to be alot more complicated/difficult. Has anyone else run into this? Is it fine to just take out each spark plug and spray fogging oil in each/replace all the plugs and turn the engine over with the kill swich pulled? Or would it be better to just run the engine every 3 to 4 weeks during the winter to keep all the parts lubed/coated? Looking for any suggestions.
