hello I am new to boating as well as this website. I bought gas at the marina shortly after my engine will not break 2500 rpms in drive Idling in nuteral I can tack it up to 3900 or higher but in drive 2500 and won't stand up on plane. I also ran a ground in soft mud I wondered if that had anything to do with it . I was also driving it when it was at 2500 and broke through and hit 3700 3900 was nice I slowed to turn and went right back to the 2500 no higher. Help do you think there is water in my gas and what would i do then... dry gas ?
