Ok, I've gotten all kinds of advice from neighbors, family and friends and all different so I thought I'd take it to the guys who know....
I'm going to drill several large holes (1/2 inch) in my transom to mount my swim ladder. I have a difference of opinion on which bit is best to drill through, wood or metal....They all say "don't use THAT kind, it wiill splinter and crack fiberglass". For small holes to mount cleats and winches, I've always used metal bits with no problem, but I reallly don't want to screw up my transom!
