Took advantage of the snow day to get some work done. <br /><br />This was the one thing I dreaded.. I didn't pre-cut the I/O hole before I installed the transom, and had visions of botching the cutout and having to rip it out and redo it. Found a 2" long straight carbide router bit and put it in my plunge cut router, and looks like I dodged the bullet. Whew!<br />
