Hello, I have a '72 Evinrude 125 and want to make a pull string which wraps around the flywheel in its spool for emergency starting if the starter goes out. Can anyone suggest if it is better to use a strong rope, or cable, and how long should it be. I was just thinking that if it was too long and the motor started it might create a dangerous situation of a twirling projectile.<br />Thanks.
