Hello Red Sky, I have a 95 Mariner 330 with twin Crusader 350XL's. Yes, you should have anodes on your shafts. If you are in fresh water, use Magnesium, not Zinc. Magnesium will be more sacrificial in fresh water, zinc will not offer the same level of protection. Zinc is best in salt water. It is all relative to the conductivity of stray voltage. The shafts did have anodes on them when new, hopefully the location will be easy to find so they do not produce any shaft wobble. You may not have much stray voltage in your marina, but you may spend transient nights in places that do have a problem. Cheap protection. Call Carver for your shaft size, mine are 1.25". I have Borg Warner Velvet drives. Carver will have your actual construction specs if you simply give them your hull number. Serial number for drives will also help them. Happy boating!
