• Check hardover time using formula:
Hardover time = Number of turns of Driven sprocket
x 3 x (Driven teeth/Driver teeth)
e.g. hardover time = 3.1 x 3 x (25/20)= 11.6
The calculated value for the hardover time using a driven sprocket with
25 teeth and a driver sprocket with 20 teeth would be suitable for this
boats steering system.
NOTE: For larger boats a longer hardover time of up to 15 seconds
may be more appropriate, in this case choose a driver sprocket with
fewer teeth.
