Hey Everybody,
I'm a new member to this forum, but I have been reading literally hundreds of posts trying to figure out what I can do with these stringers. So here is the problem, I apologize in advance for the length of the message, but any help would be GREATLY appreciated.
I bought this boat a couple weeks ago, its a 1966 Correct Craft Mustang, the interior had been redone, and it was just painted, and engine rebuilt (interceptor 165hp), but the engine mounts to the stringers by lag bolts, and where it mounts has rotted quite a bit, and now the bolts are loose.
I ripped up the floor to get a better look at the main stringers, and they appear to be 2x10 lumber, ( close to 10" in the front of the boat and carved down to about 4" in the rear of the boat). There are also 2 secondary stringers (one to the outside of each main stringer about 12" away). and there is lots of FOAM between the secondary and main stringer. SOOOO here is what I would like to do, and if anyone knows a better way or an EASIER way that would be absolutely great.
I planned on removing the foam (painstakingly) and get as much of it gone as i can. Then I was going to use a reciprocating saw to saw the stringer off, I was going to leave about 2" of the bottom of the stringer, then I was going to chisel out the remaining wood, leaving a 2" "sleeve" of fiberglass that I could use to put the new stringer in.
I was going to buy some lumber 2x10, i guess white oak, or fir, i was hoping to use pine (home depot wood) but it looks like thats a bad idea? Then I was going to cut the board to shape as best I could and epoxy the bottom of this sleeve then slide the board into the sleeve and epoxy the whole thing, and then glass over the top and sides back down to the 2" sleeve of glass that I plan on leaving.
So here are some problems I am having and any help would be great.
First the ENGINE, it sits on the stringers, but no engine hoist i know of has a boom long enough to get the engine out of the boat, so i was thinking I might be able to detach the driveshaft, and jack the engine up under the engine, and then just replace one stringer at a time, to hopefully give me enough working room. any thoughts? I was also thinking about maybe trying to slide it over, about 6" would be enough i think (its an inboard engine) Any Thoughts????

Secondly does anyone know of any better way to remove wood then with a chisel as it is probably going to take a long time, as the back 2/3 of the stringer is rotted, but the front section is completely solid (i drilled holes to check).

Finally can anyone give me a walk through of the process, as they have done it or would do it. Including the materials used, for instance, type of lumber? type of epoxy? glass? also i have heard you are supposed to lay something down between the wood and the hull, is this just epoxy or is it something else?
Thank you so much for any help you can give me, sorry again for such a long message, ive read tons of posts, but i just want to make sure i am doing this the best way, or to see if there is anything easier i can do, as this is a LARGEEEE project apparently.
Thanks,
Kevin P.

You are on the right track. You will need to find a hoist to lift the engine. Call around to the rental centers, or mabye a wrecker with extending boom will do it for you.

Regarding the stringers, the popular materials are plain 2x lumber, 2x pressure treated lumber (fully dried) and plywood (laminate 2 pieces of 3/4").

Any will do and you should completely encase them in fiberglass to prevent future water damage.

Often, rotten stringers means a rotting transom. So look at that too.

Check out shareaproject.com where you will find many photo documented projects that include stringer and transom replacement.

Lots of folks here have done what you're planning. So there will be many more opinions comming shortly - - -

Kevin, #1. Get a dust mask and eye protection and wear it! Once you get FB dust and mold in your lungs, it does not come out.
then go here:
correctcraft rebuild I am sure you can get most of your correct craft answers there. You can dig your old wood and foam out with a small electric chainsaw. $30.00

Don't worry, it will not cut the glass hull.
Good luck, Eric

See my project

You might try making a router guide to remove the rot. Screw the guide into the top of the stringer and munch away the rotted bits..

I rebuilt a rotted transom with "Git-Rot" and I was very happy with the result. It's quite expensive but does save a lot of time. A quart however only treats about 100 cu in of wood. So, depending on the extent of your rot, you might want to consider it.
