I put in a call to a local mobile marine repair place. I would like to watch someone else replace the bellows, grease U-joint, ionspect gimbal and check the alignment since I have never done it. Any ideas on the estimated cost to do just this?
Yes, I need to actually get a set of freshwater anodes (magnesium?) and zinc anodes for saltwater. This is because in the summer I trailer the boat to Maine where it is freshwater and the rest of the year it is in brackish/saltwater in Florida. In Maine it is in the water for 3 weeks straight but in Florida it is only 4-5 day trips then back the garage.
I think the boat has zinc anodes now as the outboard seems to look worse after the 3 weeks in freshwater in Maine than when used in salt in Florida.

This is from the "Zinc's Bible" I have had for years. Folow it and you will be fine.

The reason for the above recommendations is that the relative conductivity of the various waters is different. The protection potential (actually measured in volts) is progressively stronger for the zinc, aluminum and magnesium alloys. Magnesium is the highest and used in the water with the least conductivity, fresh water.
Once anodes are physically depleted by about 50% of their original mass, they should be replaced.
