You know many years ago I thought about making a fiberglass mold to produce shipping containers for outboards, I could line the inside with foam and maybe make a few adapters (auxiliary larger foam inserts) to allow for variating cowl dimensions).
Maybe; small 1-5 hp, medium 6-12hp, large 13-20hp
Then people could store, ship, or protect their outboards instead of outboards all smashing all around in shipping or in the shed or in the back of my truck.
I never got around to it…
Plus I was concerned about gas that people might put in it. And the effect on foam and the case.
