One thing that you did not mention. Do you store your boat where it is safe from freezing?
Assuming that you do you may want to consider the following:
If your boat is in the water for day use only change the lower unit oil every other year.
If it is in the water for the season I would change it annually.
You may want to start the engine and shoot some fogging oil into the cylinders. This can be done by hooking a garden hose to the water intake.
Change the water pump impeller every 3 years.
Hope you recover from your injury soon.
