Have a three blade folding maxprop on my 1997 35' Beneteau
When it was up on the hard
this year we noticed what looked like growth on the prop. Not from algae but instead it almost looked like cement. A boat
neighbor saw it and said it is from a leaky current
somewhere in the boat
We used some chemicals and a flat headed screwdriver to chip away it but dont think I got all of it.
Someone then suggested I replace the anodes with magnesium ones to help with this.
The boat is only used in freshwater.
1. Having never replaced the anodes - are magnesium the right ones?
2. Can these be replaced while the boat is in the water
or does it have to come out to make the change?
Any other guidance here? First time working through this.
