Would seagull engines benefit from a sacrificial anode ?

[Horsley-Anarak]

I did think that with all of the recent reports of badly corroded bolts, that a retro fit sacrificial anode may have some merit.

I realise that it would not reverse any existing corrosion, but if one has just spent many hours restoring a beloved seagull would it not be worth trying to stop additional corrosion.

It could be a simple bolt on to the skeg item.

I have a 4HP Merc that has a little zinc anode bolted to the gearbox casing, so Mercury must think is worth doing.

If and only if you left the poor engine sitting in the water. An anode would lose its electrons to the current in the water over a period of time, rather than the slightly more noble alloy. Just having a zinc attached wil not be of benifit during normal storage. Of course if you are making ocean crossings, by all means, bolt one on...
