I have one of the transom mounted adjustable auxillary motor brackets on my boat. It is aluminum and wood, I am going to be rebuilding the wood part which is where the motor clamps to, It appears that it is about 1 1/4 thick right now and just a piece of wood. Iam going to cover the one that I make to replace it in fiberglass. I am wondering what type of glass would be best for this and the order I should lay it on I don't think I need the fiberglass for strength as there is nothing on the current piece of wood on there, mostly just for water proofing so I think all csm should do but I am open to opinions and suggestions and I would be curious to how many layers to do. It mounts to the adjustable aluminum part by four bolts and just wondering if I should drill these four holes before I do any F/G and somehow line the holes with F/G as well. I have a very dry 1/4inch piece of quality exterior ply that I would like to use however this would require me glueing together 5 or 6 pieces to get the thickness would this be ok for something like this? I hate to have to buy a thick piece of quality ply when I have a nice dry quality piece sitting aronud. Thanks in advance for any advice and tips.
