37 PC zinc size and location


NEED MORE NFORMATION, LIKE WHAT ENGINES DO YOU HAVE, OUTDRIVES, ETC. ALSO, WHAT KIND OF WATER DO YOU BOAT IN?
 
WITH SALT WATER, YOU MUST USE ZINC, OR ALUMINUM FOR BRACKISH WATER. YOU SHOULD HAVE SHAFT ZINCS, TRIM TAB ZINCS, AND POSSIBLY ONE PENCIL TYPE IN EACH MANIFOLD. NOT SURE IF YOU HAVE ANY SHAFT BRUSHES OR NOT, BUT CHECK, MAKE SURE THEIR IS NO WEAR.
 
No shaft zincs just gull mount zincs off the stern. Need to know the size. I am not familular with "shaft brushes" can you elaborate.?
 
My stern zinc is about 8 1/2x4 1/4x1 oval zinc with 5 in. on center holes. I usually by my zincs from The Zinc Doctor great prices. I don't know if yours are the same size. I would check with TAG team at Formula. My boat was not built with shaft zincs but I do put them on and they do wear. I do have shaft brushes. It's a wired grounding bar bolted in the hull and laying on the shaft. They do have a wearable piece of metal on them.
