I think it might be because your shaft zincs are further away from the prop thaat they are protecting than the bullet zinc on the aft hub of the prop. The bullet to fit my H5 Aotuoprop is quite expensive and I have to order it from AB Marine in RI so I tried putting a doughnut zinc next to the prop hub just aft of the strut and forward of the prop hub by about 1/4 inch, it barely fit in there because I aslo have a Spurs rope cutter on the shaft. since doing that I have not had to replace the bullet in the last 4-5 years and I will use it next year as well but the doughnut zinc installed just forward of the prop in June is used up when I haul in Oct and so is the teardrop zinc that I install forward of the strut. Before doing that I would use an expensive bullet zinc in 1 season.
