I have noticed my 18 gallon gas tank has been having the sides "suck" in as the gas is being used. I am going to replace the hose and gas vent on the side of the boat, any other options for this? Also, my motor has been cutting out at full throttle which I am assuming this may be a result of the gas not getting to the motor fast enough.
def a venting issue.... make sure the vent line is not blocked, be it by gas in the vent line, or something like a mud wasp making his home.... hose could also be breaking down and collapsing on itself. is your vent line above your fuel fill? post a pic of the layout of fill and vent lines
Be careful running the boat like, drawing to much vacuum can cause a major mechanical failure. Your in the right track though, start from the tank vent and work back to the motor until its fixed.
