Marine Tex or Git Rot?

[NewmDawg]

I am repairing some water damage to my transom. I have 2 other posts on my issue and have got some great advice/help already on this forum, thanks!
Water leaked in through poorly sealed tranducer holes on bottom of port side. I have removed all holes, heat & air drying them. Once I have them dried out which product would be best to use, Marine Tex or Git Rot? I am new at this and been reading as much on here as I can before I do the repair. The drying process has probably another week to go. So far from what I can tell the transom and wood still seem pretty solid. No felxing or movement and no sign of weakenss at the motor bolts and tapping it I did not come across and "dead" spots. Probing the holes the wood seems ok, not mushy but wet. The water that originally came out of the holes was a little brown, so that has me worried. I have Marine Tex and had planned to inject that to seal the holes & then gel coat over. Also, any advantage to drilling holes on the other side (bilge area) of tansom to help it dry better or is this not recommended at all? Thanks for your help.

I believe Git Rot is for applying to rotten wood inside stringers and transoms and it is suppose to penetrate to help bring back the structural integrity of the wood. I've never used the stuff so I will not comment on whether works or not. Marine Tex is thick and will not penetrate the wood, it is only for gel coat repairs.

Thanks sarmst100.
I guess my next quesiton would be... Can they (or should they) be used together? EX: Once dry inject git rot (allow to cure) and then marine tex the screw holes? Or are these two not compatable? Again, not sure if my transom has rotten wood or just very wet/soaked wood. The water was a little brown so that is my big concern, treating and hopefully stopping any wood rot that may be happening. I would like to do this repair the right way and only once!

You have to make sure the wood is as completely dry as you an get it before making any type of repairs like this.

Git Rot, and other comparable quick fixes are basically Epoxy that is thinned with a solvent, this allows the very thin epoxy to flow into the cavities created by the wood rot.
The thinned epoxy flows with a capillary action, like a paper towel absorbing moisture. This works best when gravity is also used to help the epoxy flow, so if the holes you intend to inject the git rot in are on the bottom of the soft spots, you may want to drill a hole on the top end of the soft wood area to allow the epoxy to flow as far as it can into the rotted wood.
These type of Epoxy fixes work on the thinned epoxy flowing into the rotted sections, then, allowing time, up to a week for the solvents to evaporate and the Epoxy to actually cure in the cavities.
If not enough time is allowed for the solvents to evaporate you can trap the off gasses from the solvents and the curing epoxy inside the repair , creating voids, which are as bad as the original rot.
Once the epoxy is cured inside the rot, you an seal the outside holes in the glass with the Marine -Tex.

Great info, thanks alot BASSCAT! I'll continue to work on the dry out and see how I want to repair this.
