Hey Alan ...
Good and Fast work done there, looks great.
I got a suggestion you might give some thought, since you are right there.
I know you drilled the mounting holes, and the drive strait through, just like they are suposed to be, but here's something I do just as a little precaution to displace trapped water in the drive cut-out. I'm sure you noticed the transom is set in at a 10 degree angle, the gimbal housing is designed so the gimbal bearing and inner transom mount aligns with the crank shaft in the motor parallel to the keel (strait through) thats a 10 degree (down) angle from the angle of the transom, OK, because the drive hole is cut out strait, that creates a little water trap on the transom, directly under the exhaust port, where the exhaust pipe bolts to the gimbal housing. I know, it's only a couple of spoons full, but it is a trap. Two things I do, I cut out a little groove there to let the water run out of that area, just deep enough to go under the inner transom plate, then I mix up a little resin, thinned with a some mek, and I give the whole cut-out a couple coats to soak into the wood, you may be surprized how much will soak into that wood there. Then when I mix up the next batch of resin, for the finish coat on the transom, I will give that cut-out a good bath in it.
One more thing, on the gimbal housing, the bottom mount bolts, with the anodes on them, I am sure to check the condition of the little rubber gaskets on them, and I don't put anything slick on them when I install them, to avoid them splitting when they are tightened up from inside the transom, I do put some sealant in the holes, but not on those little gaskets.
