Transom Riser for a 22 cruiser?

Oh man!

So is is exactly what I want to do:

And I'd guess is is e boat Dr. Bob was referring to when he said he'd seen things like this done in Alaska.

AND, this boat was for sale about a year before I was ready to move on to a CD22, AND it was for sale in ALASKA!!! Cry

Who were the owners? Anyone know who owns it now? I'd love to talk to them. I wouldn't close in the transom though. I'd open it up and put a seat across, and maybe a sissy door through to the bracket.

Now I'm thinking I'd just skip the whole riser,many go for this. I love it!

The most important thing to get from the other experimenter will be his structural analysis. If he has had that done by a marine engineer, it will be invaluable for you as you press forward. If he has done the TLAR method of engineering, you would need to be cautious about copying his design. (That Looks About Right).

Good luck, we will be excited to follow your progress though I'd not do that mod to my boat.

He is using the standard long shaft--not the extra long.

The splash well seal up and bracket is a fairly common modification. (not especially in C Dorys). Also some remove the splash well, and put a solid transom, then the transom extension. If I was younger and that would fit what I wanted, I would not be hesitant to do that type of modificaion--I would probably want one of the early boats prior to 1987.

No what I had seen was in Wrangel and it was a Bayliner, 23/24, where the engine was removed. The cockpit, and transom were covered with Al diamond plate, and then an extension was done using an extra long shaft outboard to power the boat…Welded up out of Diamond Plate. It was floating--but a little low in the water. I probably have a Kodachrome slide of this somewhere.

I have seen others similar--but not on a C Dory.

Is a fairly common mod around here, but more frequently seen when an inboard is converted to outboard. This I withe final goal for me. A transom riser would be a stopgap solution to use the new outboard. One of the best things about offshore brackets is getting the motor up higher. While I don't expect I'll be getting the outboard I had originally started this thread with, I might still want to go 5" up. We shall see. In the end, there's nothing wrong with my motor and it's been well maintained.

My hull is a 1993, so still pre mass-production, but post thick transoms.

Lets go back t the reasons for this mod. I love many things about my boat, but the cockpit space is not one of them. There is a lot of space taken up by the splashwell and lazarettes. I'd like to take those out and have more deck space. I could take out the fuel tanks and put in saddle tanks, and then have more space. Not sure she I'd out the batteries, but maybe under the v berth to offset some port weight. I also carry 630' of rode (30' of it chain) up front, and with my boat set this way, does not drain water to the stern with full tanks. Plus that weight distribution aft can be offset by bracket buoyancy.

Point taken about THAL engineering, but the proof is in the pudding. A broken clock is still right twice a day.
