Default Closing the transom.

I made my first cuts into the original transom on March 9, 2009. The plan was to close the transom and add a bracket. In late 2020, I considered a cutout without a bracket, but adding back the splashwell was going to be as much work as a bracket. But I did think about it.

Transom is 2 sheets of 3/4 ply, inside face got 10oz cloth. Stringers (dry) were extended back to the transom. I added a small limber hole, so the water that collects outside of the stringers can drain. Hopefully I won't regret that.

I used 3 layers of 1708 and mat to fill the cut out. I should have gone with 4 or 5 layers, or just cut up one of the unused deck hatch panels. I put the drains about 8 inches in board, so they drain right on to the tabs. I spent a lot of time trying to figure out how to get the hydraulic steering cables and transducer cables through the bulk head, without spending $500 on cables. At one point I was about to order $1500 worth of thruhull transducers because I didn't want to put a 1"hole in the new transom...I ended up buying the uflex hytech kit because its beefy enough for the merc 150 efi (e.g. rated to 175 hp, unlike baystar), and modifying a Scanstrut Multi Deck Seal to get the 1" simrad tranducer through.
