Labatt-

Galvanic corrosion is still a problem in freshwater. However, zincs made of zinc are not generally reactive enough to provide your boat sufficient protection in fresh water. Fresh water boats should have either aluminum (brackish water usually) or magnesium (pure fresh water) zincs. If you've got zinc-alloy zincs, they can often not be affected while the aluminum parts of your boat get attacked.

You should also keep a notebook on the boat, preferably in the maintenance log, that lists the important consumables and what their size/part numbers are, so you don't have to haul the boat to figure it out. Oil filters, fuel filters, impellers, zincs, clevis pins, shear pins, and other things like that should be on the list IMHO. Also, might want to list various fuses and what amperage is used for what circuits.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
