Gday guys.

Building an Air boat out of Coro-plus. The Hull is 55cm long and 34cm wide.
Im planing on mounting a OS LA46 on the back. I think the engine is a little bit big for the hull size,
but i'm up for a bit of a challenge.

Now for the question-
Im up to making the engine stand. Im planing on making it out of some
3mm ply than fiberglass around out. than bolt it to a sheet of ply, than Glue
the sheet of ply to the bottom on the hull.

What would be the best way about mounting the engine stand to the hull?
Is Ply and fiber glass the best way to make the engine stand, or should it be made out of some alloy, if so,
how would i mount it.

Thanks alot guys
