anode bolt replacement follow-up question

[rebars1]

The anode bolt kit I got includes a rubber washer, but I'm not sure where to place it. The Merc manual says to place it between the bolt and gimbal housing to act as a seal, but the on-line diagrams show it going between the bolt and zinc. Any opinions? Merc 225s 1974, ford 302. Thank You.

Im not sure about the rubber washer, but I do know that the zinc must have, metal to metal contact on the componant that it is designed to protect.

Wow. Perfect description of the bolt, Bondo, and installation info. One question I have though is what is the "bonding strap" and what would the other end conect to? Is it like a ground strap to the engine?
