Motor bolt hole question

[phatdaddy]

squid, that transom looked like it had some work done to it. whats in the holes now. if its just bare wood. i'd probably take some epoxy and coat the wood, then 5200.

on smaller stuff like transducers, swim platforms, etc. I've done the over-drill, then completely fill hole with epoxy. after curing, drill pilot hole and mount screw.

I charge a whole lot of money to take motors off that people used 5200 to mount them. You should have to have a permit to buy that stuff. Life caulk works fine and isn't permanent. If you want to do it right, drill the hole over sized to fit a piece of 1/2 ID PVC, CPVC or PEX pipe. Coat the inside of the hole with epoxy, making sure to cover all exposed wood, coat the outside of teh tubing and insert it in the hole, wait till it cures and cut it off flush. Now when you mount the engine, only use regular silicone

Thanks for the feedback. The transom has bare wood in the hole now. But on a good note it's dry wood. Think I'll just get some 5200 and use an acid brush and brush it in the holes for a couple coats then just use LifeCaulk to seal the motor on. I've read horror stories about using 5200 to actually seal the motor on. And as much as I pull motors off that's the last thing I'll need.

I don't know to much about that but I do know that 5200 3 m is supposed to be permanent If and when you have to remove the engine it's going to be a real hard time your going to have I would not go by what I said but I would ask the heavy hitters and see what they suggest you to use

I'm thinking about putting a couple coats of 5200 in the bolt holes and letting it dry completely then seal the bolts with LifeCaulk.

I drilled my holes a 1/2 inch larger than my motors bolts. I then hotcoated the holes and taped one side closed. I then filled the hole with thickened resin and then glassed 2 patches of 1.5 csm on either side. The next day i drilled the holes to the actuall bolts size leaving 1/4 ring of glass around the bolt hole. Now this is the extreme end of the spectrum! And almost a little radical. Hot coat with West Systems 105 then use 3m 4200. I used 5200 on my first motor i mounted on my boat....when i took it off to put my suzuki on it pulled the paint and some gelcoat right off. I would west systems and 4200 if i did it again. If yo dont have west systems use a vinylester resin or a thinned polyester resin

I heart this thread. Not advocating 5200 ideas but deinstall damage pales in comparison to years worth of water intrusion. The worst that can be done is not sealing at all... Appreciate all the ideas as I am hoping to repower really soon.
