    Do a compression test first. Then maybe try pressure testing the engine. You may have an air leak from the crank seal.
    If all of that checks out, you may need to rebuild the carbs.

    Sounds like you may have a little external water leak. You'll want to fix that.
    You could still take it out on the water for a bit if you want, but keep an eye on that water leak.
