I/O (Sterndrive) Conversion to Outboards

[tpenfield]

Having done quite a bit of fiberglassing recently, I tend to go with the longer (wider) piece on the first layer and then progressively narrower pieces on top, when doing open lay-up (i.e. not vacuum infused).

The reason being is that going short -> long yields air pockets in the areas within the laminate where the wider pieces transition over the shorter pieces.

I've seen it reccomended both ways is why I asked. I know FAA is small to large but they're typically bagging if memory serves (and as you said).

Honestly I don't know that any of us are stressing the materials enough to have it actually matter all that much... as I think back to my boat with minimal structure in the tabbing and no caps.

can you not use the VE stuff or PB i see yall talk about to feather the possible voids?

It wouldn't be as strong as a continuous laminate... and the slight angle of the layup at the overlap is "weaker" as the glass is only strong in it's plane.

Hey @tpenfield How is it going, have you faired in the pod? I find myself looking forward to your project more and more.

It's going . . .

The bottom seam is all filled in and glassed, and the entire pod is sanded in preparation for fairing compound (VE fairing compound).

I'll be doing the fairing compound today and perhaps sanding it smooth on Friday (6/5/2026)
