Got a 1/2" drill bit and some 1/2" dowel rod. Measured (about 10 times for each size) after cleaning the holes out with the drill (decent lookin wood came out). Sanded them down, then mixed my epoxy resin. Didn't make much (around 2" in a plastic cup .. yes, I got the 3:1 ratio correctly). Painted the inside of the holes, then painted the dowels with the epoxy, put the dowels in. Painted both sides (in and outside of the boat) with plain resin.<br /><br />Then I had some leftover resin (actually, a bunch) so I got out the cabosil. Dumped in some and made a little less than a putty mixture. That sh** gets HOT in a hurry that way! <br /><br />Spread it over the holes (1mm or so) on the outside of the boat. Will get to the insides tomorrow, probably. <br /><br />Also will run a drill bit into the other holes in the back of the boat and fill in some more of that putty stuff in those, to seal em up good. Sunday or Monday I'll get all that sanded, then I'll call my buddy Dan (best friend / cant wait to go boating with me / good helper) and have him come over to horse that heavy motor on there (so i can mark / drill the new mounting bolt holes). Then I ought to be able to mount the motor on there. With the motor mounted, I can get it into water (trash can) and see whether or not I'm going to have to pull the LU...<br /><br />How long do I actually have to wait to start sanding?
