"Measure Twice. Order Once."
Measure cable routing path from wheel center to engine connection, as follows:
*
A = Center line of wheel to gunwale (or deck, if routed downward),
B = Dash to Transom,
C = Gunwale to centerline of cable connection at centered tiller.
For Cable Installations through Engine Tilt Tube:
Add A, B and C +6", then round up to the next foot. Order that lenth
cable.
