I have to agree with dorelse, if your going to change to outboard you will have to start from scratch. When I did my jet make over I took it down to the bare hull, rebuilt all stringers and "beefed" them up because you never know how much more stress your going to put on the new project when you change everything and where that stress will show up.   And I've also taken enough of these apart and know if any wood is rotten, all of it is..  Good luck.  And keep them on the water!

I've read through the thread again, and the one thing I can't seem to find is a budget for the project.  A full stringer, floor, and transom rebuild is expensive, and a 23 has plenty to replace.  Not trying to throw a wet blanket on your dreams, but it will take a lot of time and money to restore back to an I/O configuration, likely more to make a conversion.  Shawn would be an excellent resource to determine costs involved, though a number of other enthusiest on here have done them as well, Shawn just more recent than others.  As for your current status as shown in the videos, the glass hides the rot.  As Doran mentioned, you need to drill and inspect.  Know before you commit.  Patchwork will not last.  Much like rust repair, you have to get it all, or it just comes back.

Thanks for all the input.  Yeah, it's looking more and more like a few year project.  Gotta fit it in between the rest of life.  I've just started finishing my basement, so I probably won't make much real progress 'till next Summer. 

As for a splashwell...  I'm thinking that all I need to do is get the motor far enough back and up, that it won't be necessary.  None of the 3 pics in Hyperacme's Reply #7 have splashwells.  Am I missing something?  I plan to cut about 25" wide x 18" deep out of the swim deck, then construct a 8" fixed jackplate , then add a 4" manual jackplate to that. 

How "beefy" is a beefy stringer?  3/4" ply x total height, plus a 3/4" x 2" top reinforcing strip, glassed over with something really tough? 

I haven't yet determined a budget.  The following are my best guesses, which might be way off: 
Boat purchase & transportation (done)   $900.00
Outboard purchase & transport (probably Yamaha OX66 225hp)   $3,700.00
Outboard controls & cable   $400.00
8" Fixed Jackplate + 4" manual jackplate shipped   $350.00
Will I need new gauges?   $400.00
Battery   $100.00
Stringers, floor, transom, wood etc,   $1,000.00
Paint or gel, fiberglass filler, etc   $500.00
Paint / Gel spray gun & other tools   $200.00
Foam   $500.00
Labor for the places where I get stuck   $1,000.00
Total   $9,050.00


Ouch.  That was a little more than I was thinking.  But I also have no set timeline, so it can be done as funds and time permit.

Your estimate might be a bit low, but you can re coup some money selling the transom plate, manifolds, engine parts, etc.   Probably hang onto the trim pump till you know the final configuration.  Many parts can be found reasonably at swap meets, Craigslist, eBay and such.  Finish the tear out, then you'll have a better idea of what you need.

To do the transom on my CV16 cost about $400 ... Wood/2 1/2 gal. poly resin/fiberglass/measuring cups/catalyst/etc.
Your $1000 estimate is pretty low ...
 
Express Composites is the best !  Very helpful ...

A Seastar hydraulic steering system will run you about $1000.
SeaStar Solutions No Feedback Twin Cable Rack-and-Pinion Steering System will be about $500.

Not sure what mods would need to be done to stringers to turn it into an outboard.

If I remember I went threw five, 5 gallon buckets of resin on my 23 rebuild. If changing and cutting transom I would add one more bucket. I also had to replace ALL the wood and re-core the front deck. As for thickness of the transom mine was two,  3/4 plywood boards and about 5/8 inch of glass/resin for a total thickness of about 2 1/8.

I think the 1,000 for floor and stringers is fairly close (wood, glass, resin).
My thoughts below.

Boat purchase & transportation (done)   $900.00
Outboard purchase & transport (probably Yamaha OX66 225hp)   $3,700.00
Outboard controls & cable   $400.00
8" Fixed Jackplate + 4" manual jackplate shipped   $350.00
Will I need new gauges?   $400.00                 Yes I believe outboard and inboard are different may be wrong. Mine new were about 200
Battery   $100.00
Stringers, floor, transom, wood etc,   $1,000.00
Paint or gel, fiberglass filler, etc   $500.00. I would add about 1,000 depending on color and if you are doing the whole boat. Sandpaper and tape add up quickly Try SPI Inc. for paint I used it on my last 2 restorations and it worked really good.
Paint / Gel spray gun & other tools   $200.00
Foam   $500.00 I can't remember what I spent but I don't think it was this much.
Labor for the places where I get stuck   $1,000.00
I think this has become an addiction.

Anybody wanna buy a CVX23?  :)

Kidding.  Not ready to give up yet, but wow.  I know there's a lot I don't know, but I'm learning the extent of that.  I really appreciate everyone's help. 

Fireman24 - I'm learning a lot from your thread.  Are you saying that the Paint or gel, fiberglass filler, section should be $1000, or did you mean $500 + $1000? 

If I could find a donor boat with a big engine, that might be the way to go.

I would budget 1500 for paint, primer, sand paper filler, etc. Just buying the paint gets expensive.  I used SPI Inc universal clear and their epoxy primer on the last 2 boats I did. The one I drove for about 4 years before selling and the paint held up really well.

I found a donor boat for my rebuild and took the drive assembly, engine accessories, wiring, controls , and a few odds and ends off of it. 

It will be a lot of work to convert it over Good luck.
I think this has become an addiction.

I read through your original post again. Correct me if I am wrong but it sounds like the motivation for the outboard it so you can put in a larger L shaped seating area.  In reality you are only going to gain about 2 maybe 3 feet of extra room on the one side of the bench. When we are out in the boat anchored or beached. there is almost always someone sitting on the rear sun pad on the boat. Also the passenger would be sitting sideways while moving, most people will want to face forward while under way.

Just a thought, but changing it to an outboard vs rebuilding it like stock will be a lot of work and will only be a minimal gain in my opinion. I personally would prefer the sun pad over seating for 1 maybe 2 more people.  Also keep in mind the capacity of the boat. Just because you can seat 10 people don't mean you can have 10 people legally on the boat. 5-6 people on a boat gets crowded pretty quickly considering where are coolers, food, cloths, towels, toys, etc going. I put most of that stuff in the back storage next to the engine on mine.
I think this has become an addiction.

Good point Shawn. I know for my wife the sun deck is a necessity!
