I had the most bizarre thing happen last weekend at a race. I was testing my 45 Eagle, I brought it back in because I was having trouble with the steering. I found the entire transom was dislodged from the boat, thinking I must if hit something although I never saw it hit anything. I got the boat home and torn down and believe it or not the main transom plate and the end cap had come un-glued from the boat.

Has anyone else seen this and if so what is the best way to repair. I am thinking I might pin the transom with some toothpicks and maybe wrap the transom with carbon cloth.

I have heard that you can tear the transom out of these boats if you hit something but this was very odd.

Yes you hit something.

Has happened to me and I believe its designed that way so it doesn't kill the boat.

Clean it up and reattach. I used epoxy but someone may have a particular epoxy they use.
 
I had the same thing happen to my 90 Eagle I cut a V slot between the transom and the tub sides filled with epoxy and pinned it with 1/8 inch dowels its been good ever since..........Good Luck
 
David,

Thus is very common on all wood boats. You can pin it you can put a v slot on it and then epoxy back in place but go one step further you have the right idea take a piece of carbon cloth make sure you catch both the top and bottom deck the body sides and the transome in essence making a little box out of the carbon fiber and epoxy it on place this will make a very stout transome and give you years of service without and chance of it coming apart again. Good luck

I have it repaired now, I just cleaned up and sanded everything, glued the transom/bulkhead in place. Glued the backplate back on and then wrapped the whole back with carbon cloth and 1" on each side. Off to paint now !

Thanks all !
 
I've gotten a older SGX .67 that has been pined. A few of the pins were coming apart near the rudder. I drilled and taped the side do the rudder bracket ,then adding bar stock alum ,redrilling the front alum stock thew the side of the tub. Bolting in-place using larger washers on the inside of the tub.

Actually it's not "common on all wood boats". I had it happen to 3 of the SGX riggers that I used to run (my 45, 90 and twin SGXs all did it) however I will say that 2 of the 3 were clearly from impacts with debris in the water (damaged rudder blades) and the way the transoms separated on them made for easier repairs than if it would have been pinned, almost as if Andy and John designed it that way.

This was definitely not an impact issue. It appears that water got between the endcap and transom and that cause the glue joints to fail. I hear you about pinning them. I hope the carbon strap around the back will be strong enough.

It happens to most SG and older SGX boats.

All the newer boats are pined with dowels.

Have not had any problems with my new boat as fare as the transom goes.

Drill some very small holes from the side and put servo mount screws in with some epoxy on them.

It will not come out again.
 
We have started pinning the transom the last couple of years with 1/8" dowel. Some guys tore out more than one or two of our transoms and some never any. We made a habit to only tighten the rudder shear screw and pivot screw lightly so that if we hit something the rudder would easily kick up.

I have since decided that pinning the transom is a better choice. The damage may be more sever if the rudder is clamped very tight and the boats hits something very firm, but for the majority of small impacts the whole system will live more often. Whichever method is used to secure the transom, using lightly tightened screws on the rudder blade will save many broken transoms.
 
Go to Home Depot and get some 1/8 oak dial pinnes they come in 3 foot sticks I hit a baby gator with a Eagle 40 one time got my reel and throwed it with a big treble hook and reeled in boat and gator the rudder was in the gator would have lost rudder but i had a steal water line in the tub gator could not swim cause the blade cut in to his back .
 
Thanks Andy, in my case I think I didn't seal something or I developed a crack etc. In the end it does not look anything like and impact as much as maybe the glue joint getting wet. Well offered idea on the rudder though. Now that I have wrapped the transom with carbon cloth if I hit something it could do a lot of damage.

Seawolf, wild story about the gator!

BTW, I need a couple of struts for the .45s, do you have those in stock ?
