Protecting transom from rotting

[MCL]

Im just about to finish a lengthy boat rebuild with epic proportions.Part of this has been converting the transom from volvo to merc.
The transom has been completely redone and sealed to stop the wood from getting wet.I still believe that no matter what you do with time water will always find a way to soak your transom and rot it.

The wood in the transom is dry as the boat has not been in the water yet,I was wondering of saturating the wood with some fluid that will preserve it,wont freeze and protect it from rotting.For example if the wood is already soaked(wet) with oil it cant fill up with water.I was thinking of drilling a hole on top of the transom in the boat and let the wood soak fluid through that for a couple of weeks.

Has anyone tried anything like this?Any suggestions about what fluid to use,oil,coolant etc?Ideally you would want somethign that wont freeze,has rot protecting properties.

not worth the effort oil will cause its own issue with the bonding and with anti-freeze, you have to allow the wood to dry as well.

if you did a good job encapsulating everything, your all set for well over the rest of your life or until you sell the boat.

just keep all the penetrations into the wood from actually getting wet. seal every screw with UV stable 4200

what I did, is everywhere there was a thru-transom penetration, I had a void in the wood that was filled with a chunky version of PB (lots of chopped fibers. that way all penetrations go thru a solid chunk of fiberglass vs any wood.
