Thanks for all the advice on my zig zagging problem. Now, one more.....5.7 Alpha One. The bolt which holds the trim anode in place is rusted and needs replacing. Problem is, the hole above it is too small for the Allen head to come out. Really don't want to remove the lower end of the outdrive to get the bolt out. So...is there any reason why I can't drill the hole out slightly so the bolt will come thru?
