Introduction to Control Cables & Overview
||< Previous Page|Next Page >|
SeaStar Solutions offers several models of universal
3300/33C type cables, each suited to certain operating
conditions and installation parameters. Below are key
variables that affect how cables perform:
Backlash: the lost motion between the amount of
movement put in (input end of the cable) and the
amount of movement which occurs at the output
end of the cable. Some motion is generally lost in
“take up” between the inner wire (core) of the cable
and the outer casing (conduit). Backlash manifests
itself as free play (slop) felt at the control handle.
Efﬁciency: the percentage of input force that is
transmitted through the cable as output force.
For example, if a 10-pound force was exerted on
the cable at its input end and resulted in the cable
exerting an 8-pound output force, the cable would
be 80% efﬁcient.
Breakaway: the “feel” of the cable when put into
motion; the breakaway threshold is the force that
must be applied to the cable’s input end before
something happens at the output end. An example of
excessive breakaway: a control that would have to be
moved to half-throttle before the engine responded.
The control cable is a very important component in
the control system. It is the vital link between the
control head and the propulsion unit. Employing the
best cable helps insure that your shift and throttle
system operates smoothly and efﬁciently. The design,
technology and materials, which are used in SeaStar
Solutions cables, have literally set the standard for the
entire marine industry.
Our control cables are environmentally tested
for marine applications. They have stainless steel
terminals and conduit ﬁttings, as well as stainless or
nylon covered core wires with moisture protective
seals for added corrosion protection and longer life.
Their durable HDPE outer jackets resist abrasion and
withstand the effects of UV, salt water, chemicals,
gasoline and oil. Each SeaStar Solutions cable is
lifetime lubricated at the factory.

this technology there can be signiﬁcant operating

Cable Routing: the shorter and straighter the cable
routing, the better the cable will perform. With
increased length and bends, cable efﬁciency is
reduced, while breakaway and backlash rise.
Environment: generally, the more rugged the cable
construction, the longer the cable will last. In harsh
environments such as heavy salt and UV exposure,
control cables with thicker conduits and stainless
steel ﬁttings will generally outlast those with thinner
conduits and brass or steel ﬁttings.
Cable design, manufacturing tolerances, length and
installation care are additional factors to consider.
