DAY SAILER II transom is plywood cored for full width of transom as far as I know, and my own DS II seems to confirm this. I'd skip the bracket and just clamp the outboard right to the transom as O'DAY designed it to be. Even using a short-shaft this will work, I had a 1992 2.3 HP Johnson on my boat originally and it worked fine, you may get a bit of ventilation if you hit a wave, but it will work! I attached a 3/8" thick piece of plywood to the outside of the transom to protect the gelcoat and make the outboard more secure. The only problem is that the transom on the DS II slopes the wrong way by a few degrees, a bracket won't really fix that anyway. The only thing that does is tocause the stern to be pushed a bit down and the bow up when you apply full power, My boat did have a fixed bracket when I bought her, if it had been offset to port instead of to starboard...maybe I would have kept it, but the other problem was that the previous owner had used 3 stainless-steel bolts and one galvinized steel lagscrew to attach it and the lagscrew was rusting and staining the hull. The holes weren't adequately sealed either and I had to dry out the plywood core in that area to prevent rot. I have since added a plywood mounting board to my transom to tip the outboard back so that it is more vertical than when clamped to the transom direct, however, I have a long-shaft (20") 4hp Johnson now so there was no proble raising the motor a few inches on that board. I should mention that I added an afterdeck onto my DS II, sort-of like the one on the DS I, but I'll post a few pictures of my outboard mounts. I can take a picture of the inside of the transom, showing the bolts, but won't be at my boat until Friday.
