    It clearly is setup for prop. As far as engine setup.... probably best to get the approximate weight and the pitch of the prop and diameter and reverse engineer the approximate power needed. With emissions limiting engines the last decade or more it might be hard to find a suitable replacement. If the prop is really low pitch maybe a re purposed jet ski motor. Kawasaki made a lot of small 2 strokes back in the day.

    Here is what you most likely need. Old air cooled ~5 hp marine 4 cycles.

    Since its a ride-on-top of a certain era, and doesn't look like it ever had numbers, I wonder if it isn't a theme park livery boat.

    It looks like a fun project, but would probably be more effectively driven with a jet ski motor/pump.
    By the time you find a suitable inboard and possibly a transmission, and properly install all that, you’ll have spent a lot of money for questionable results.
    Jet ski units are powerful and light, and it looks like you may have easy access to such items.

    I do actually run a jetski shop out of my home I have about 30 skis atm and tons of motors ect that is my goal to cut out a 550cc stand up kawasaki to put this 550motor into by cutting the whole 550 hull pump and tunnel along with motor mounts so I don't have to worry about moving motor mounts and eliminates all the wastes time fabricating mounts ect

    Those old Kawi 550 jet ski motors are incredibly noisy, and were fairly inefficient at pushing the skis, especially at getting out of the hole. Pay attention to the weight/ displacement of this new hull in comparison to the motor’s donor craft.
    It was just mentioned here in another thread how critical matching components is in a jet drive application.

    Well here is a single seater with a 570 cc 18 hp motor shaft driven prop. Although they have more freedom boat building regs wise in some parts of the world.
