How to choose the shaft with S or L or X?
Pls choose the shaft size based on the transom height of your boat.
Transom height of boat: S=15" (in.)
Transom height of boat L=20" (in.)
Transom height of boat X=25" (in.)
How to choose the correct model?
Suffixes for different models:
B=Back control (Tiller control), F=Front control (Remote control)
M=Manual start, E=Electric start, W=Electric start + Manual start
S=Short shaft , L=Long shaft, X=Ultra-long
Theoretically speaking, the propeller size of a boat is determined on the boat’s load, heavy boat with small pitch
size & light boat with large pitch size.
