Brunton H5 autoprop anode

[poultey]

Having replaced the anode positioned at the rear of the Brunton prop ( three plastic bolts that expose the prop retaining nut when removed) when on dry land, I'm interested to know if this job could be done with the prop submerged without adversely effecting the prop.
Water ingress between the zinc anode and the brass prop interface is surely inevitable in the absence of a seal and the prop retaining nut covered by the anode presumably spends its life immersed in water despite the presence of said anode ?
Since the only maintenance required at this point is the replacement of the anode I'm reluctant to pay for a haul-out and have the means (scuba) to perform the anode replacement work (outside the marina confines) while submerged. Any thoughts appreciated.

Provided that you're confident in doing the job underwater, there's no reason why not. As you say, it's only three (8mm) nylon cheese headed screws, with slots for a screwdriver. Just be careful not to drop anything. It doesn't pretend to be watertight.

It's no problem replacing in the water. Other than the sea being cold in UK waters. And murky. It's possible to do it in snorkel gear, actually. I've done it.

I have not replaced my Bruntons anode underwater although I see no reason why this would be problematic. I have removed and replaced a Stripper rope cutter by snorkel in Corsica, where the water was warm. I hung a bucket under the prop to catch any parts I dropped, fortunately not needed.

have you no maintenance / scrubbing posts nearby ?

Not readily available and I'm quite taken with the idea of being able to inspect the hull underwater and perform tasks, rope removal around prop etc using an 8 minute 1 litre scuba tank and mask.
