Thanks for an interesting video! One small point – bonding all the metal through hull components together doesn't seem necessary to prevent shock risk – you need at least 50V difference between two places someone can touch to drive a potentially fatal current through them and this seems very unlikely. If a boat was moored in such a strong electric field I think it would also very rapidly corrode any metalwork in the path, and the battery negative connection would also be irrelevant. Connecting the metalwork to shore power earth might help but would also mean bigger currents and faster corrosion.

I have a Fiber Glass boat. PropShaft has been removed there is a piece of bronze that's glassed in for the cutless bearing. This has a plastic cover on it. Should I put a zink close by or does it need to be in contact with the bronze. Thank you

Step 1: buy fiberglass boat
Step 2: sell aluminum boat

So when you talk about a “season” can you be a little more specific, 6 months, a year. Why do I ask? A boat may not come out of the water but once per year or in autumn and then back in the water in the spring.
So is once per year haul out and check adequate?
And if we find the zincs less than 50% we need to increase the anode size or quantity.

Hello, I love the video! Would you also be able tolet me know where to put the anodes? How many do I need on a 29meters long boat? Thanks in advance.

Anodes do not protect the gear box plate/engine unless the anode in in the same electrolyte if we are talking about Cathodic Protection. If we are talking stray current or earth leakage then bonding to the anode is so that when the current returns to source, it leaves via the anode and metal loss only occurs at the anode, not the skin fittings or props. Spring washers should not be used to attach the anodes but serrated washers to ensure electrical connection. Caution when you apply any loc tight to any threads as it can insulate the studs from the nuts, thus preventing electrical connection from the anode to the studs. Get your Z-Gaurd anodes via Marathon Lesuire this winter

I subscribed because of this information. Thankyou!

He placed it the wrong direction it will cost some additional drag to boat

You can replace them under water we dive inspect hulls and replace anodes all the time.
