To choose the correct model, you MUST measure from under anti-cavitation plate to the bottom of the skeg, as shown by ‘Dimension A’ below.

To select guard size by propeller diameter only is NOT recommended.

Example: If this distance A measures 12″ exactly, the guard diameter that you should buy is 12″ guard diameter, model 91112, as shown in the table below. If you measure over 12″, 12-1/4″ then round up to the next size. In this case a 13″ guard, model 91213.
