Redid mine with 2 sheets of 3/4" coosa, but sterndrive so don't have the weight of any outboards hanging off the back. 28lb density I believe.

If it's not available in your area, I think it would be worth a long drive to pick some up. Shipping is more than the cost of the coosa itself.

And remember, coosa won't rot but it ain't any better than plywood if it gets wet and delaminates.

Something I wish I had done when bedding mine to the outer skin.... there is stuff called Trevira Mat by Prisma. The use it on all there pre-forms. Would be great to lay down over the outer skin before you bed rather than a layer of CSM, fills voids and rough surfaces very well. Maybe use it between layers of core as well.
