    Welcome to the forum.

    That's a pretty ambitious project, particularly where you're starting from. I don't how much HP you'll be asking of this 460, but having built a few, you'll need to seriously look at some structural considerations, before you start tabbing things in.

    Plywood works and is easy to work and fit, though there will likely be places you might consider something else, like Cossa, just to get the durability out of it. Post a few pictures of what you're working with and this would help a lot.

    This fellow did a restoration as well.
    You should really find a Nordic jet boat forum or even a jet boat forum pertaining to the type of boat that you have.
    If you have a Berkley Jet you need to ensure that the impeller is the correct cut for the horsepower that you are building the engine for.
    As most of our boats were meant to run 30 - 40 mph, with a 460 454 with about 330 hp ahead of the pump, we always used a A3 impellor, designed to carry some weight
    They would, with enough hp, carry a boat to close to 70 but with maybe 425- 450 ahead of the pump.

    It’s had a 460 in the boat originally the pump and everything Handel a 460 with 500 hp the reason for a rebuild is a crack block from a rod
