Preparing for spring
 

I need some help. I removed my outdrive for the winter. Now I am starting to think about spring and getting the boat ready. Even though it is still months away here in northern Maine. What should a buy and replace before the outdrive goes back on. The drive is a Bravo 1 and only 1 year old while the bellows for all I know are 13 years old as the boat is a 1990. Are there gaskets and such that should be replaced. Any help is appreciated....
