    The experts will need your serial number in order to reply.

    It could be a lot of things!

    Specifically what battery do you have and how old is it? How old is the gas? Is it treated? If so, with what? Any gas smell? How old are the sparks plugs...type and gap?

    Ball is hard, Schrader valves nothing, other than top starboard very little bit of fuel.
    When turn on ignition sounds like pump charging

    I do not see any Interstate Battery on the recommended list. http://www.bbcboards.net/showthread....batteries+meet The 27M-XHD meets the minimum JUST FOR THE MOTOR. If you add a graph(s), pumps, Power Pole pumps etc, it will be more than what the battery can handle. It might work ok in the beginning but will be killed pretty quick. Here are Don’s words...



    I’m not saying this will fix the problem but these ProXS motors have are huge electrical load.

    If it's the 31-AGM Interstate battery will handle motor, pumps, 2 large graphs, 2 talons, and a 360 just fine for a full day of fishing and then some. The list isn't constantly updated.

    I would double check your battery connections and MPR. Any warnings beeps when this happened? Also check your compressor.

    I have a 2017 200 Pro X/S, Was doing the same thing, I could smell gas once off the water, problem on mine was a crack in the Fuel Rail. Noe saying that is your problem just one of many possible issues.
