HOW TO MEASURE STEERING CABLES “MEASURE TWICE. ORDER ONCE.”
If possible, find the part number stamped on the
plastic jacket of the old cable. If you removed the old
cable, measure for the replacement cable as follows:
For Rotary Steering Cable Replacement, Measure
Existing Cable as follows: Measure plastic cable jacket
(“Y” dimension, shown in above drawing) in inches,
add 18”, and round up to the next foot. Order that
length cable.
For Rack Steering Cable Replacement, Measure
Existing Cable as follows: Measure plastic cable jacket
NEW INSTALLATION:
Measure cable routing path from wheel center line 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 the Engine Tilt Tube:
Add A, B & C + 6”, and round up to the next foot.
Order that length cable.
For Cables Mounted to Transom, Splashwell or Stringer:
Add A, B & C, then subtract 6” and round up to the
next foot. Order that length cable.

A single-cable, starboard drive push-pull mechanical cable system
is shown in this diagram. If your mechanical system is different
than the one depicted and/or you have any questions about
mechanical steering after reviewing this guide, please contact
SeaStar Solutions Technical Service.
Cable routings (such as those found on pontoon boats) may vary
from this drawing. Confirm length by laying a garden hose (or
similar object) along cable path and measure run from wheel to
engine connection point.
(“Y” dimension shown in above drawing) in inches,
add 30”, and round up to the next foot. Order that
length cable.
For JBS Jet Boat Cable Replacement, Measure Existing
Cable as follows: Measure cable from tip to tip. (Round
up to next foot if needed for whole foot.) Order that
length cable.
JBS helms are ONLY for smaller jets such
as Mercury Sport Jet
®
, OMC Turbo Jet
®
, etc.
and look like the helm depicted at right. If
your jet steering is different, contact
SeaStar Solutions.
If your engine does not have a tilt tube cable connection as shown
below, see “Connection Kits” pages later in this section to get the
