New to operating boat motors and just bought small jon boat with 1970 20 hp Johnson. The motor is hand steered and controlled from the motor. however, the previous owner rigged up an electric start and throttle in front of boat that is easy to operate. The question is, does that setup prohibit me from using the throttle controls on the motor steering handle? I am unable to twist the throttle into action...I have never operated one from the handle throttle, am I missing something?<br /><br />Any help would be appreciated - thanks.
