Transom repair???

[SkunkBoat]

I've said it before in other transom threads but a viable shortcut would be to expose only the top edge of the transom at the motor cutout. Then use the chain saw to remove as much wood as you can reach. Try really hard to clean the inside of the hollowed out transom, block all holes and then pour 2 buckets of Carbon Core.

This would skip the hard part of cutting the cap and removing the motor well.

I recommend CarbonCore over Seacast because it really pours and leaves no air pockets.
