400: Hull Anodes

[Mixman1]

I am buying a 2011 Lagoon 400. I would like to change all the anodes during the survey haul out. The SD-50 anodes are a no brainer, but I can't easily find what other hull anodes there might be? Size and type and bolt hole size is the info I am looking for I guess.

No data, only a picture for start...

This is on the port hull. Picture should be turned 90deg to the right.

Thank you for the help! I figure I might as well refresh all the anodes at the survey quick haul.

The part number (and part) will be available from the manufacturer of your cathodic protection system.

The grounding plate is available at any well-stocked chandlery.

Is your boat on the hard?
If it is, take the old unit to any well stocked chandlery.
If the old anode is fully depleted, just measure the distance between the bolts and show the picture to the chandlery.
You can also buy it online. Boatzincs.com

Boat is in the water so I’ll dive under & take measure
Thanks

You don’t have to dive. Open up the bilge above where it is. You can measure the bolts right there.

That’s a great idea, Thanks!��

The cathodic protection system uses a specific reference electrode. It is not a generic hull anode found at West Marine or BoatZincs.com etc.

Do you know who manufactures the CPS for a 2010 Lagoon 400?
