Working on getting my boat together for the first time ever. I've never had it in the water and been rebuilding it for a LONG time. it is a 30' Velocity with twin 650hp and TRS drives. I just had the drives gone over, new u-joints, seals, etc... and noticed today that one has a 'skeg' style anode and the other has a flat anode. Would there be a reason they were different from side to side? Which might I want to use? Not my pics, just showing the two types.

use the flat version on twins. The fin style was used on singles with no power steering so you can "adjust" the angle of that fin to compensate for prop torque and trying to force the boat to one side...

Thank you! I'll go that route. Appreciate the quick input.
