MAINTENANCE AND LUBRICATION
OUTBOARD JET DRIVE
BEARING LUBRICATION
A grease gun and tube of grease is supplied with your jet drive. We recommend greasing
the bearing every 10 hours. Make greasing a part of your cleanup after the days use.
Pump in just enough grease to fill the lube hose. Then reconnect the lube hose coupling to
the zerk grease fitting.
Every 30-40 hours, pump in extra grease so as to purge any moisture. The texture of the
grease coming out gives an indication of conditions inside the bearing housing. A gradual
increase in moisture content indicates seal wear. If the grease begins to turn dark, dirty
gray, the bearing and seals should be inspected and replaced if necessary.
Some
discoloration of the grease is normal during the break in period on new sets of seals.
We have selected a water resistant grease of the proper consistency for this application. If
you use a substitute grease, be sure it is water resistant and of the same consistency.
IMPELLER
Your jet drive is equipped with a key to protect the unit in the event of a rock jam. This can be
reached by removing the water intake, and then the driveshaft nut, similar to a propeller drive.
After replacing the key, pull the shaft nut up tight to remove any play between the impeller and
shaft. Note the position of the impeller shim washers, and replace them in the same order.
REVERSE GATE MECHANISM
Occasionally check adjustment of the gate shifting linkage. In "forward" the gate should be
firmly locked in position. Pull on the gate by hand to verify this. This will prevent wave action
from accidentally shifting the gate into reverse as the boat is violently maneuvered
GENERAL
Check all mounting bolts, intake screws, linkage connections, etc., occasionally to be sure they
are tight.
SALT WATER USE
Aluminum and stainless steel have been used in the construction of your jet drive. These
materials have either been treated or are inherently resistant to corrosion. It is recommended,
however, that when not in use the motor be tipped up so that the jet unit is out of the water.
When used in salt water more than in fresh water, remove mounting hardware, grease, and
reassemble once a year.
Failure to do this may result in hardware that is difficult if not
impossible to remove at a later date.
GUARANTEE
Due to inflexible government regulation, we do not have a written warranty. We have, however,
a good reputation for fairness with our customers which we intend to maintain. If you think you
have a warranty situation, regarding material, workmanship, call us before making repairs.
