Notice to Boat Manufacturer, Installer, and Boat Operator
Throughout this manual, Warnings and Cautions (accompanied by the International Hazard Symbol ) are used to alert the manufacturer or installer to special instructions concerning a particular service or operation that may be hazardous if performed incorrectly or carelessly.
Warnings alone do not eliminate dangers, nor are they a substitute for safe boat handling and proper accident prevention measures.
Observe these alerts carefully!
These “safety alerts” alone,
cannot eliminate the hazards
that they signal.
Strict
compliance to these special
instructions when installing,
operating or performing
maintenance and using
common sense are the most
effective accident prevention
measures.
DANGER
Immediate hazards which WILL result in severe
personal injury or death.
WARNING
Hazards or unsafe practices which COULD result in severe personal
injury or death.
CAUTION
Hazards or unsafe practices which COULD result in injury, product and/or property damage.
NOTICE
Information that is important to proper installation,
operation or maintenance, but is not hazard-related.
For example:
CAUTION
Do not tighten cable hangers or clamps to the extent that they crush or stress the cables in any way. Doing so may impair the function of the cable.
The information contained in this manual is believed to be accurate at the time of going to print but no responsibility, direct or consequential, can be accepted for damage resulting from the use of this information. The manufacturer reserves the right to make changes, without notice, to any of its products.

INSTALLATION
Section 1: Location of Control
1.1 Allow adequate clearance for hand lever swing (forward and reverse positions).
1.2 Allow adequate clearance under the console or in the gunwale for the cables AND allow a minimum of 36″ from the cable nest connection with no restraint. When supporting the cables beyond 36″, do not tie or clamp tightly.
1.3 After a suitable location for the control is determined, use the separate mounting template.
1.4 Closely follow the instructions provided on the template. Cut & drill the mounting holes required.
On all models, the cover will have to be removed to expose the mounting holes.
Tools for Installation
Phillips head screwdrivers Standard slot screwdriver
Saber saw 4¼ ” Hole Saw (optional)
Power drill 7/32″ & 17/64″ drill bits 3/8″ box end wrench Multimeter (optional)
5/8″ or 16mm deep well socket Ratchet wrench
Section 2: Measuring the Cables
Measure the cable routing path from the control head connection to the engine connection.
Outboards:
Measure from the control connection — along an unobstructed cable routing –to the center of the outboard engine. Add four (4) feet to the measurement to allow for a loop which provides unrestricted engine movement. Round UP to the next whole foot and order the required cable part number. (Last two digits of the Teleflex cable number equal the length of the cable in feet.)
Inboards & Stern Drives:
Measure from the control connection — along an unobstructed cable routing — to the SHIFT or THROTTLE connection. Round this dimension UP to the next whole foot and order the required cable part number. (Last two digits of the Teleflex cable number equal the length of the cable in feet.)
