    Welcome aboard, jpt!

    Yea, it would be too easy if it ran in the water but cut out on the trailer...

    90% of the time it's a fuel problem. Carburetors/fuel pump/filter gummed up from improper storage and old gas. Try changing the fuel filter first. If that doesn't help, don't continue to run it because it will likely be too lean, damaging the pistons. In that case, overhaul the carbs.

    Also check that both plugs are engine running on 1 cylinder will rev fine out of water but doesn't have the power and will bog when you put it in the water.
