Operation

Propellers

• A propeller can be very sharp. Be careful when you handle
it. Wear a pair of protective gloves when handling any
!
propeller.
• Remove your key from the ignition to prevent accidental
starting of the engine.
• DO NOT reuse the nylon locknut or the cotter pin.
• DO NOT use a damaged propeller. A damaged propeller can
damage your engine and/or your boat.
Nothing is more important to the proper performance of your boat than the condition of
the propeller. Even slight propeller damage can mean the loss of one MPH. Greater
damage can mean considerably more speed loss. Worse yet, damage usually is not done
to each blade uniformly and, therefore, sets up imbalanced vibrations that can cause
fatigue damage to other parts of the engine or drive system.
Your propeller is custom calibrated for your
Axis by our Research and Design team to
give maximum performance. Before
installing props other than those suggested
by Axis Wake Research contact your dealer,
otherwise adverse handling and top speed
characteristics may be experienced.
The prop is identified by two numbers, i.e.,
13 x 14, and material identification such as
brass or stainless steel. The first number is
the diameter of the prop and the second
is the pitch. The pitch is the angle of the
blades and is measured in how far the
boat will travel through the water in one revolution. In this case, for every one revolution
the boat will travel 14 in.
Do not operate engine above the manufacturer's
recommended RPM rating; severe damage could result,
!
voiding the warranty.
At least once a year, more often if you use your boat extensively, you should have your
local Axis dealer inspect the propeller for any possible damage.
At least once a month, if you use your boat regularly, you should check and tighten the prop
nut. If it is necessary to remove the prop, use care. If the prop is not removed correctly, damage
could result if it comes off the shaft too quickly and hits the ground. Whenever possible, use a
prop pulling tool to remove prop, this will reduce the chance of damaging the prop.
