1976 22-2 rebuild, factory inboard to outboard conversion
« on: May 22, 2017, 01:43:07 AM »
Yesterday I brought my first Aquasport home. She is a 1976 22-2. This will be my third boat build from the hull up, so I am not 100% new to the basics, but this will however be my first experience in glass. I worked today until I ran out of daylight removing bits and pieces, and will be cutting up the floor next to see what I am really up against.

This boat was posted for sale on here for a bit, a couple hundred miles away.  I went into this one knowing that she was going to be a full rebuild, so a soft floor and no motor didn't scare too bad. I was told she started life as an inboard, but the inside of the transom has me wondering. Behind the gas tank was a skin that looked like that of a short transom outboard setup. Maybe some of the experts can shed some light here.

I will be building this one with some serious west coast flare. A crab winch and headlights are mandatory equipment for our nocturnal Dungeness harvest. For power, I would like to hang an outboard (or two) off the end with a bracket. This boat won't be used in any shallow water, so a fixed mount with a platform with some room to stand on and clear props is the direction I am thinking.

I have a long road ahead, and I will be documenting the whole bit. Thank you guys for all the information you have made available, you've been a ton of help already. The amount of love here for these boats make me feel like I picked the right hull to build upon. Even the wife got excited and started wrenching.

I remember this hull. If it was an inboard, there should be a nice hole in the keel where the shaft resided. The inside of the transom looks like a modified outboard but who knows what has occurred over its lifetime. :ScrChin:

Interesting.

Good luck and keep posting pics with your project. :thumright:

That part of the transom is just the liner. They built the core and everything else behind it as a full transom.

Capt. Bob,

You are correct. No holes yet though as I still haven't removed the prop and rudder assemblies. As soon as the floor is up those will be coming out. I'll throw those on the classified section in case any inboard guys are looking for hardware.

Rick,

Thanks for the transom liner info. More progress pics to come shortly.

It's not just the transom liner, it's part of the whole inside of the boat - "the liner".

Rick,
I misspoke, I should have said the liner's transom. Now for the amateur questions. It looks to me that in most of these rebuilds, the floor is mounted directly to the outside hull and stringers, without reusing the liner. Is there any reason to keep the liner installed when doing a new floor/sole?

If you look at the liner it is the entire inside of the boat to include the inside hull sides, the floor and the casting deck up front. Then you have the cap....  So you have to figure how far you want to go.  The hull sides of the liner are covering up the raw glass of the hull itself, so it you remove it you'll have a lot of fill and fair ahead of you. I think I would dig through the rebuilds here and see what others have done and make your call then.

After removing the floor keeping the rest of the liner will make for less finish work and also a nicer finish on the inner hull sides.

Thank you both for the replies regarding the liner. I have some good food for thought now. I'll make a decision on that one after I get into the floor just a little deeper.

Got the transom mostly stripped of hardware. The console electronics and hardware disconnected, console removed, gas tank and hardware out, and would have started cutting out the floor but it started raining on me. Will pick up tomorrow where I left off. Slow but steady progress.

Huge day today. I got into the groove early and rocked and rolled until dinner. I got the floor up all the way to the casting deck, removed the remaining prop and rudder hardware, and some plumbing. Once the sole was up, I found the two channels outside the stringers filled with foam. This had to go so I could access to the stringer sides in order to raise the stringer tops and reglass. Surprisingly, the foam was very, very dry. once the foam was out, I started in on the motor mounts, and the crossmember that held the blower and intake hoses. With those out, I began the transom core removal process by cutting out the ends of the stringers. To my surprise, the foam there was dry as a popcorn fart too. I am guessing the stringers were re-foamed when the outsides were done. There are several 3" holes in the stringer tops to support my theory, but one can never be sure what has been done in 40 years.








The only real bummer I found was a pretty good crack in the cap forward of the transom. Making lemonade from lemons, this looks like a good place to cut it and build in a bit of storage.



Amateur question time. From what I gather in the build threads, it is not as critical to raise the floor in V-hulls as it is in the flatbacks, but that some height increase is a good idea. What is the consensus on a proper sole height increase for reliable deck draining when hanging an outboard from a bracket? 1.5", 2", something else?

Good progress. Raising the sole 2" will be a good goal and will help in draining water off if you change the COG with a heavy motor or bracket, etc.

I would raise the floor to the top of the chalk that is at the base of the liner that you left in place.

Thank you for the replies gents. That liner chalk you are referring to is an easy spot to aim for. Should give me 2.5" or so rise. I found Coosa board locally today, so I've got that going for me.  Couple more weeks of teardown and grinding and we should be ready to start putting some glass down.

I've removed the transom portion of the cap, and the liner, as well as the interior skin of the transom. I am now into the plywood. The plywood is bad enough to be discolored, but not bad enough to be easy to remove. With any luck, I'll have the plywood out by tonight. Not moving very fast though so I thought I would take a break, and take a look at the removal methods of the many that have been here before me.



If anybody has a favorite method, I am all ears.
