Hi all,
I've managed to source some stainless props for my DP290. However, I hear they burn through anodes much faster than aluminimum props do (I'm in salt water in a permanent wet mooring and need to use zinc anodes).
I've heard of a couple of solutions:
1) retro fitting an extra anode to the top of the cavitation plate
2) hanging extra anodes off the props when not in use
Has anyone done either of these before, and if so, how do I best go about it?
Is the cavitation plate a solid piece, so I just need to drill and tap a thread into it to attach a large dome zinc anode?
As for hanging anodes, is it literally as it sounds, as in having a metal cable with a couple of zincs on it and leaving it on the props? I obviously don't want to damage the props of course, and I've heard even using a wire brush can introduce mild steel which then oxidizes on the props.
