I wish I had screwed a temporary block of wood on the inside of keel before I drilled the prop shaft hole. I had tearout and the drill bit went a bit off center when it came out. Even though it will be covered up with the shaft log, it still bugs me. If I ever build a boat again I think I might just cut a slot instead of drilling a hole.

Re: Drilling the prop shaft hole.
What kind of bit did you use?
Drill bit? forstner? hole saw?
I them all, and found a hole saw to be the best,
Yes, you need a tear-out block, preferrably on both sides.

Oak is over rated, everything about it takes extra time; then it warps, splits or checks !!! 

Re: Drilling the prop shaft hole.
Here is a link to a post that showed the hole saw I made. Easy to make, cut through fast, and it cuts straight and won't wander like a drill bit.
