Temporary stringer repair options

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm helping a friend replace his ring gear on a pcm motor/trans. After removing everything, he checked where the transmission mounts to the stringer. It has 4, 3", 3/8 lags that hold it in place, 2 on top and 2 on the side. The rear 2 are both totally rotted and a screwdriver can go from the hole on top to the hole on the side of the stringer, even thou they are offset an inch or so. The front two are holding. After using some cpressed air and hand tools it doesn't appear to be to far along.
     He doesn't want to tear into it in the middle of the season and actually wants it back in the water this weekend (lol). Can someone recommend a temporary repair for the rest of the season? He was going to fill it with a generic 2 part epoxy. I'm sure west marine would have a better (temporary) repair product. I've had a blow dryer running since last night on the damaged area. Thanks

	Epoxy in the holes is probably the only thing that will help. It isn't ideal and certainly doesn't mean that it will be more structurally sound, but that's a fix that could help for the season.

	I'd recommend using CPES (clear penetrating epoxy sealer) and then fill the hole. The CPES will treat the rot.

	Im not sure its accurate to say that CPES will treat the rot, but its probably your best chance to solidify whatever stringer mush remains. Homebrew will work fine- just thin some epoxy with xylene and pour it down the bolt holes until it wont take any more. It may take a day or 2 to set up, but once it does, back fill the top of the holes with epoxy resin thickened with a high strength filler (milled fiber, etc). Once that dries hard (overnight), consider grinding the gel off the surface around the mounts and reinforce the area with a few layers of glass. Then drill new pilot holes and reinstall the tranny. This is far from a proper or professional repair, but it should buy you a little bit of time before doing a complete stringer job.

	He is going to inject west marines "6/10" epoxy kit and deal with the major work over the winter. Thanks for the advice.

	Tr, I agree. His feeling is the rot isn't to far along and doing a more invasive repair would mean he would lose at least this long weekend. If he does a Permanent repair at the end of summer it probably won't matter.
