Pacific Seacraft 40 Anodes

I am a new owner (to me) of a PS 40. I have one anode on the maxprop, and one small teardrop on the gudgeon. Is this sufficient? How long can I expect them to last before requiring replacement? Any thoughts and advice welcome.

Our experience aboard JUNO (PSC 40 -- #46) is that the life of the zincs seems to depend a great deal on the nature of the waters where the boat is (i.e. ocean vs. estuary, marinas vs. anchorage or mooring).

Generally, the MaxProp anode is eaten rather quickly -- every two or three months. The gudgeon anode seems to be more long-lived -- a full eight-month season.

In terms of advice, I make a practice of checking the MaxProp anode periodically going over the side with a mask. It is possible to change it in the water as long as you're careful with the retaining screws. The only other MaxProp advice I'd offer, as has been discussed in other threads, is to use an appropriate zinc antifouling (MaxProp recommends a Pettit product) on the prop as barnacles tend to find the props very attractive for some reason.

Best of luck with your new boat.

. . . and of course it goes without saying . . . not at the marina if there's shore-power due risk of electrocution.

I tape a wire to the propeller shaft and attach it to a zinc hung over the
side, plus with galvanic isolator, I can get a year out of them when in salt
water, 2 years when in briny water.

Re: Pacific Seacraft 40 Anodes

We had been burning through the MaxProp zinc on our PSC 40 every 3 months or so in a crowded salt water marina, but after installing a galvanic isolator, the zinc replacement interval increased 2X or 3X. Installed a "ProMariner ProSafe FS Galvanic Isolator - 30 Amp" below the electrical panel.

That's really only an issue in freshwater.

I hear, if one suffers from electric shock drowning, they can be resurrected 9 years later.

Re: Pacific Seacraft 40 Anodes

As Fstbttms said, "That's really only an issue in freshwater."

From https://www.electricshockdrowning.org/esd--faq.html,
"WHAT IS ELECTRIC SHOCK DROWNING?
Electric Shock Drowning (ESD) is the result of the passage of a typically low level AC current through the body with sufficient force to cause skeletal muscular paralysis, rendering the victim unable to help himself / herself, while immersed in fresh water, eventually resulting in drowning of the victim. Higher levels of AC current in the water will also result in electrocution. Electric Shock Drowning (ESD) has become the catch all phrase that encompasses all in-water shock casualties and fatalities."

It happens all the time... https://www.electricshockdrowning.or...nd-events.html
