J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Engine Zincs in the 2GM

I`m not sure what engine is in my hull 361, but there is 2 zincs.One is on the starboard side and one on the aft end of the engine block.You will see the large nuts(bolts) and these have the zincs screwed to the inside of them.The nuts(bolts) dont have any other purpose then to hold the zincs and are quit noticeable.
