I only have about 12" of shaft in contact with salt water so the prop-nut zinc bullet works well and lasts for 18+ months to 1/2 way.

I don't need to add any more metal (engine and raw-water system)to an insulated shaft so no thanks. This would also require adding zincs to protect the cooling system as I would be connecting the prop and shaft to it.

Have the bonding system analyzed with proper test equipment and by a skilled operator to determine need.
