Re: Working on sail drives without haulout?
TD, if your saildrives are like mine, you'll have two sets of zincs per drive: one split in half around the front part of the drive and three separate "ring" zincs around the shaft just aft of the hub. The split zinc uses an allen wrench of one size and the ring zincs another. Taking those below the surface, holding your breath while loosening, removing, replacing and tightening again gets old and is difficult while just using a small allen wrench.
I took a 1" piece of PVC and drilled two holes through it, inserted the larger allen wrench through one set of holes and the smaller through the other, facing the opposite direction - zip tied both in place and now I have a dedicated "zinc" tool that has a better grip, better torque and is easy to spot if I do drop it while down there.
Hope this helps,
