Looks like I'll be doing some stinger work too....the tops are soft around the holes seen in the photos. Below appears to be pretty solid. I will tear into them with the grinder in a few days.

In the meantime, I got the transom wrapped in CSM....one more small area to go.

I have holes in my stringers, but I put them there. Looking good though. There are lots of boats out there running around with transoms worse than yours, so it doesn't surprise me that it held up. It's the boat as a whole that makes the transom strong.

I'm really glad to hear you're going to replace your stringers. Since you have come this far I really believe you should do it all and make sure it's right.

Good news - the rot is only partially infesting the stringers and concentrated around that hole. I am going to remove the rot, rebuild the section of the stringer, and re-cover it with glass.

I feel pretty comfortable with leaving the stringer as is after the repair.....I don't see any use in removing the entire stringer. I will however do some more test holes to check it else where.

Re: Considering my first Transom Repair

Quick update - The transom is glued in!! I will post photos later this evening.

After I fillet the edges, I'm going to install the Biax....but I have a newbie question.....which side get laid up against the transom? The CSM side or the woven side? I'm sure there is no difference in strength, but I'm sure there is a difference in laying it up on the inside corner.

The CSM side should go toward the outer skin.

As promised - PHOTOS!!

Notice the stringers I cut out.....

I added several more clamps around the top, and ran a bolt through the bilge drain to pull the bottom back to the skin....worked well.

Tomorrow morning I'm hoping to get the first layer of Biax in after filleting.

Houston we MAY have a Slight problem. When installing the Transom it is customary to use Thickened resin. This allows for any gaps to be filled and the squeeze out can be use to fillet in the sides and bottom of the hull. My fear is using the resin as you have that your bond may be weak. Your clamping was GREAT but... the resin, In my opinion was not sufficient for the application. Let's see what others have to say.

Re: Considering my first Transom Repair

Although the photo doesn't show it, the resin is thickened. My wife took the photo before I got through the first cup of resin. There is about 32 ounces of peanut butter thick resin on there. I used a trowel (seen in the second photo in the bottom right)to even it out afterwards.

There was at least 0.25 inches of resin on the skin before putting the transom in. It squeezed out of every hole....even a few I thought I had already filled.

Re: Considering my first Transom Repair

I have made quite a bit of progress since my last update -

The transom is filleted, and two layers of Biax have been applied. The stingers were repaired, and tabbed in to the floor and transom with Biax.

The replacement foam in the floors was poured, and new floor sections covered in CSM and installed, then filleted, and tabbed in. I began drilling holes for the through-hull fittings to find that none of them fit anymore....I ordered more from iboats.

Lastly I poured new foam on the side of the boat to replace what had been removed for tabbing.

List of items to complete: pour other foam on the other side, cover both sides in CSM and tab to the transom, put the cap back on the hull, finish the through hull items (drain tubes, ladder, eyelets, and pump fittings), mount the motor.

I'm hoping to hit the water this weekend - we'll see.....

Photos coming up next.

The foam will be smoothed out and shaped to match the original before receiving a coating of CSM. You can see the biax layers, and the floor tabbed in, as well as the stringer.

The last of the foam was poured and shaped last night. I filleted the edges, and then tabbed it in creating a box between the hull and the floor/transom areas.

That completes the re-construction!!! I'm hoping to drill the remainder of the necessary holes, and put the cap back on this evening.

There is still a little clean-up to be done in the bilge, but its pretty much done. I was hoping to hit the lake this weekend, but the lake is 19.80-feet above the full stage and the majority of the boat ramps are closed.

You've done a real nice job on what is definitely a little bit of an unusual transom design. Great work!

Re: Considering my first Transom Repair

Its almost done!!!

The cap is mostly back on...I have to lift it again and shift it around a little. I think I need to do a little griding on the back side of the splash well to get it to fit right.

I'll post photos tomorrow!

Re: Considering my first Transom Repair

The last three days have been pretty productive!!

Friday all of the through-hull fittings arrived - new hose fittings and new brass tubes for drains. They were all installed same day, a couple were left for Saturday.

Saturday I got the cap back in place. Because of the difference in transom thickness a few adjustments had to be made....the rivet holes didn't line up. I had to drill new ones at about 1/8 to 3/16 of an inch forward. Once that was completed, the rub rail was riveted in place.

Sunday I finished up the cap, put a new piece of 1-inch x 1-inch aluminum angle across teh back s the factory had it. Problem was, there was a gap between the stainless plate that goes across the width of the splash well and the aluminum angle. The bolts also didn't line up since the cap was 1/4-inch up a little (again thickness of the transom). Once that was complete, I was able to line up the motor, bolt it up with nice new stainless 1/2-inch hardware.

The shift/throttle cables and steering were connected. Lastly the fuel tank was drained of most of the fuel left over from last year...I left a few gallons in. With just a few cranks, the motor fired!

The last few items to button up this week: Mount the motor controls, attach a seat cushion, finish up the bilge pump, and put a few screws in the aluminum angle.

Thanks to all of those who answered my questions, and to those who posted their "how-to's" so I could copy what they had done!!
