what are these called?

[texas_salt]

They go onto the bolts between the outside of the transom and the wood that the motor mounts to.

Theyre about 1 inch long, fit a 1/4" bolt, and have a nut inside so you can screw them on. I need more.

They seem to act as spacers/padding but also seem to help seal. What are they called? Also, how much are you supposed to tighten the transom wood onto them?

How about a pic of the boat where they go, and the type of motor they attach to?

They're called 'wellnuts'- They go in a hole,then a bolt goes in and the well nut swells up a little as the bolt is tightened. Good for spots where there is no access with a wrench behind whatever they are in.

awesome, thats it.

These dont actually fit into the bolt holes for the transom, so I guess they acted as a soft barrier and maybe a sort-of-sealer. Have you guys ever seen these before on the outside of a transom, between the actual boat and the wood the motor is mounted against?

Nope,...... Are they holdin' the wood to the transom, or the motor to the boat,..??

They ain't very strong, they only hold by the resistance of the rubber to the wood/ fiberglass,.....

I've seen 'em used to hold a binnacle control to a dash, but not much else,....

Apparently they were just used to seperate the wood from the transom and "seal" the bolt holes when tightened. Thats it. I dont think ill order more as they dont seem to offer much.

One that was under the water line fell apart causing a slight leak. They just seem to be more in the way than useful, so ill keep them off.

I jusr assumed they might have been standard at some point to help protect the transom, but mounting wood directly to the transom seems widely common.

That is definitely NOT the right way to use those, they should never be used like that actually! They are meant for holes where you can't get to the back side with a conventional nut. Get a long bolt, thread the wellnut on, shove it through a slightly larger hole, and then tighten it. The rubber mushrooms out and holds (albeit weakly) whatever you just bolted together. Very common on boat windshields and other low stress areas.
