My control used to work fine, but now one lever is hard to move. What should I do
to fix this?
First, determine where the problem lies. There are three possible trouble areas: the control, the cable
and the throttle or transmission connection. By isolating these one at a time, you will find the problem.
Engine(s) must be OFF when performing these checks:
a. Disconnect the cable at the throttle or transmission attachment point. Move the throttle or
transmission arm through its arc to be certain there is no restriction or binding. If the arm is stiff or
binding, clean and lubricate moving parts. If this does not solve the problem, make the appropriate
repairs. Generally, the force required to move a throttle or shift arm should be no more than 5-10
b. With the cable disconnected at the engine end, try to move the control lever. If it moves freely, the
problem was the throttle/transmission arm. If the control handle is still hard to operate, disconnect
the cable from the control. If the lever operates smoothly, the control cable needs replacement. If
the lever is still hard to move, lubricate the lever pivot point in the control with penetrating oil and a
light grease.
c. If the problem is with a throttle lever, you may have a cable brake installed to limit cable feedback to
the handle. If this is the case, loosen or remove the brake. If throttle lever creep back is a problem on
the boat, you should consider installing a SeaStar Solutions CH5600P SLT control. This unit will stop
cable creep without sacrificing a smooth feel.
Each control lever has both a self-locking and direct drive lever arm. The cable
from the engine throttle directly to the control should be connected to the
control’s self-locking lever arm. The cable from the transmission should only
be connected to the control’s direct-drive lever arm. Cables between stations
should only be connected to the direct drive lever arms of those controls.
Direct Drive Lever Arm:
When a cable from the transmission or a “slave station”
is connected to the direct-drive arm, it will allow the
control lever to be moved from another station. Cables
from the main station to any additional stations must be
attached to direct drive arms on those stations.
Self-Locking Lever Arm:
When a cable from the throttle is connected to the self-
locking arm (black in color), it will only move if the lever
is moved; engine vibration and return spring feedback
will not move the control lever. Only throttle cables
routed directly from the engine to the control should be
connected to self-locking lever arms.
