You can go online and find data on which boat brands stopped using wood in structural applications and what year they stopped. That is the best indicator of how to eliminate future problems.
Fished yesterday afternoon/eve from 2pm to 7pm. Motored out of Sandy Pond and headed to 140 ft in front of the Salmon river. Rough ride to get there but tolerable when trolling. Good temp down in the 120 ft range. Only one 12 lb Coho on a Warrior Salmon Candy for nearly 4 1/2 hrs of trolling. Had a few boats nearby and never saw any activity on any of them.
These pics were taken when I was first constructing it. Another bolt was added near the bottom since these pics. The aluminum plate on the plastic motor clamp plate was added because the plastic plate wasn't wide enough to facilitate the bolt holes on the Suzuki 9.9
I have the heavier of the two Panther fixed brackets. It is rated for over 200 lbs. Beware that it does not protrude enough from the transom to allow complete tilt up. I spaced it out an additional few inches with aluminum angle. This also allowed me to adjust the height as necessary. Can send additional pics if needed.

After I read your post again I realized you are completely disconnected from the main hydraulics. The only basic difference you may have from mine is you don't have a dedicated helm for the kicker. That's deserves consideration.
Get another hydraulic steering unit just for the 9.9. mount the helm in a convenient location and put a small crank handle on it. Vevor has a hydraulic steering setup with the helm, cylinder, hoses and fittings. Oil must be bought separately. I paid about $250 for that setup about 1 1/2 years ago. Remove the AP from your main unit and install it to the new system dedicated to the kicker. I know the Yamaha 9.9 has a steering tube so the cylinder will mount on it. My system is a Lowrance Outboard Pilot controlled by a HDS 12 Lowrance but it shouldn't matter what you have running it. It works very well in any waves I am willing to fish in.
