Need help with cable measurement

[Sammy]

I'm putting a kicker on my single screw inboard . Mount is in center of the transom with a hole threw the transom from the previous owner. When I measure down the gunnel threw the hole and to the motor how much more should I add to the length?

i usually add 2' just for flex on an outboard when turned all the way to the opposite side from the cable side of the boat.

You need to consider going past the kicker, doing a 360 degree loop than into the kicker to the connection for best results
