Nice as always.

Do you weld the bridges/spacers to the external tube as well?

Thank you! Yes they are welded to the inner pipe in several sections to dam up the water and spill over on the top side to keep the entire pipe surrounded by water. I leave a small gap on the bottom to allow a little bit of the water to pass by.

You are referring to the rings right?

Yes. I cut them to size and in half, then weld them to the inner pipe leaving a small opening on the bottom so hot water doesn't get trapped at the bottom.

So, you went "dry tails"? Were you concerned about possible reversion issues? They look great!

Yes I went dry exhaust to the transom not for concern of reversion as much as just to keep the exhaust flow as dry as possible without actually doing full dry pipe thru hull tails.
