The greater the surface area, the greater the lift. We‘ll typically recommend a 9” chord tab, but depending on available transom space a shorter or longer chord tab, or specially shaped tabs with upfins or dropfins may be advised.As a general rule for boats with max speeds of 40MPH, choose at least one inch of trim tab span (per side) for every foot of boat length. For example, a 22′ boat would use a 24”x9”.For speeds 40MPH and over, we’ll generally point you to one of our Performance, or Premier Line high-performance systems.This product may not be returned to the original point of purchase.
