Steering cable lenghth ?

[labii]

The cable is for a friends boat . He put his in the water for the first time this year on Sat . The steering was frozen and he turned the wheel to hard and ground the gears out . He was going to order a NFB system and was not sure of the cable length.
As for me , I'm going in the water or on the work rack this weekend . Spring is here , 78 today and low 80's tomorrow . By the weekend it is it is going to be back in the lower 60's. I may spend the day cleaning and doing some small repairs .....
