DIY Outboard Bracket

[Kcinnick]

I am currently building a 21ft stitch and glue boat and I wanted to build a bracket suitable for a 115hp to 150hp outboard with a swim platform the entire width of the transom.

This forum has earned the reputation of the place to go for DIY brackets, and I can see why from some of the projects. I had a few questions..

1. Is standard polyester resin being used? I am familiar epoxy, but I am not sure that is the best to lay up in a mold.
2. How thick does the fiberglass need to be?
3. Is 1708 the preferred fiberglass?
4. Does anyone have the basic dimensions for the "box" or know if plans are available to make a bracket from.

I do understand you do not DIY to save money, you DIY to get exactly what you want and the satisfaction of a job well done, not to mention the best labor money can't buy.

Thanks,

Nick
