Two measurements are needed here, Shaft Length and Deck Height
Measuring “Shaft Length”
Most shafts are 15″, 20″ or 25″. If you are unsure of the length of your shaft you can measure from the inside, top of the MOUNTING BRACKET to the bottom of the CAVITATION PLATE.
Measuring the “Total Deck Height”
Measure from the TOP of the swim deck to the water line. If there is no visible water line, put your boat in the water with a normal load and then measure. This measurement is very important, do not guess.
Perform the following calculation, then select your Remote Troll:
Shaft Length – Total Deck Height = Overall Drop
Overall Drop Value
