Re: Alpha one skeg question.
My .02...
I've never been a big fan of the skeg guards. In you your case, it looks like a rock tried to slide between the prop and the skeg. The weakest component lost.
What happens when you have a stainless prop and a stainless skeg guard? Depends on the circumstance, but it increases the chance that something happens to other parts such as the propshaft. I'd rather pay for a skeg repair like yours (or live with it), than to pay for a propshaft or other internals that lose that battle.
