Trim tab - installs onto the lower unit for Mercruiser models 1967 - 1990 MC-1, R, MR and Alpha 1. The length of the fin on this magnesium measures approximately 2-3/8" from base to tip of fin.

If you are using an oversized propeller (larger diameter) and do not have the clearance to use this anode, you can simply grind the fin tip down until your propeller has sufficient clearance.
