Do I really **NEED** a trim tab?

Doing water pump service the other day I noticed that the trim tab was missing. Talking about the zinc or aluminum fin that mounts above the prop, adjustable to counter the natural pull to the right. I have no idea how long it's been missing.

Should replacing it be a priority? The pull to the right is noticeable, but not a huge deal. As for its anode function, I run in a freshwater lake and don't wet-slip the boat.

Advice?
 
Properly adjusted, that trim tab will eliminate torque reaction at the wheel, which makes boating more fun! Just adjusted mine last night.
