MAINTENANCE RECOMMENDATIONS
Proper Installation
Proper installation of Kasco equipment will include a power source with ground fault protection. Ground
fault protection devices can also alert you to electrical leaks in the equipment. It is extremely important
to test the device upon installation and every month thereafter to ensure proper operation. In the case
of consistent trips of the ground fault device, disconnect the equipment and remove it from the water.
Inspect the power cord for damage and contact your distributor or Kasco Marine (1.715.262.4488, sales@
kascomarine.com) for further instructions.
ALWAYS DISCONNECT POWER BEFORE PERFORMING MAINTENANCE.
Observation
Observe equipment in operation on a regular basis (daily, if possible). If you observe a change in
performance, disconnect the equipment from the power source and inspect for any material clogging
the system or wrapped around the motor shaft. To avoid damage to the equipment, it is important to
remove clogs as soon as possible. ALWAYS DISCONNECT POWER TO THE UNIT BEFORE ATTEMPTING TO
REMOVE CLOGS.
Cleaning
Buildup of algae, calcium, barnacles, or other matter on the motor housing creates insulation and blocks
heat transfer, so to prevent overheating, it is important to clean the unit. In warmer regions or in other
areas prone to buildup such as this, inspect and clean the equipment regularly. In all regions, inspect and
clean the equipment at least once a year. It is easiest to clean the unit immediately after removing it from
the water, when the equipment is still wet. If you use a power washer, avoid hitting the mechanical seal
area directly.
Unit Storage
Store the equipment with the cage down if it is going to be out of the water for long periods of time, such
as during off-season storage. Seals on units that sit upright on a shelf for extended periods of time are
more likely to dry out. Storing upside down or sideways will ensure oil is reaching the seals and help to
prevent drying.
Sacrificial Anode
All Kasco units include a sacrificial anode installed on the shaft to protect against corrosion and
electrolysis. Replace the anode if it is reduced to half the original size or if it is white in color. Corrosion
from electrolysis most commonly occurs in saltwater or brackish water, but it is important to check the
anode in all installations at least every two to three months.
Seal And Oil Replacement
This is a sealed motor assembly. Like brake pads on a car, seals wear out over time. Replace the seals and
change the oil after three years to increase the motor’s longevity and to avoid more expensive repairs.
Other Repairs
Seal replacement and all other repair services should be performed at Kasco or a Kasco-trained
authorized repair center. Please contact your Kasco distributor or representative to find your nearest
service center.
Please keep the original box for maintenance shipping.
