    How long is it? I had a 28 foot Tri-toon with a 175 Yamaha on it and it was great for everything from cruising to tubing and wakeboarding with the kids.
    What do you want to do with it?

    Somewhere on the boat (usually around the driver seat) there will be a Coast Guard rating placard. This placard will give you the weight limits, number of passengers and how much horsepower the boat is rated for. Look around some, the manufacturer is supposed to put this in plain sight.

    If you put a 200HP motor on a boat rated for 150HP the Coast Guard or LEO's will write you a very large $$$ ticket. Only race boats are exempt and I don't know of anyone who races a pontoon, however I am sure that someone has.:D

    How does that work for guys who have like 18 ft jet boats that have 500+ hp motors? I know over 21 ft and all limits are off but seems like on this guys 20 pontoon he could run like 150-200hp and be somewhat safe.

    An 18 foot jet boat is supposed to have the same placard, however the horsepower rating is not printed on the engine as with an outboard, so unless the LEO's have a floating dyno they have no way to know how much horsepower that V8 has.:D

    I would think that you could put anywhere from a 60HP to 125HP outboard on a 20' toon and LEO won't give you a second look.

    Also not having a legible placard is a violation and gives LEO one more thing to nitpick you about, if they happen to notice it. If the manufacturer is still in business they should be able to provide you with a new one if not then there is nothing you can do about it. Myself, I would not worry about it until it becomes an issue.
