Maintenance
Here are some guidelines for daily and periodic maintenance.
Only carry out all maintenance work with the motor stopped
and the electrical system switched off .
Every 10 hours or daily, before starting
• Checking coolant level
• Check the water filter and clean it if necessary.
• Check the state of charge of the batteries.
After the first 50 hours
• Check flexible motor mounts
10 Take out of service - prepare for winter
Follow the instructions below if the E-Line motor is to be taken out
of service for a long time. Long-term means a period longer than 3
months, for example during the winter period.
Make sure the motor compartment is ventilated. Good ventilation
prevents moisture in the motor compartment. This prevents corro-
sion.
Carry out the necessary maintenance work before taking the motor
out of service for a long time. Checks and maintenance work to be
carried out:
• Clean the motor with a cloth.
The cover plate of the E-Line motor is splashproof .
The motor supports are made of stainless steel, the other
motor parts of marine-grade aluminium .
• For raw water cooling: rinse the cooling water circuit with clean
fresh water and if necessary fill with an anti-freeze liquid. Clean
the cooling elements and tubes if necessary.
Anti-freeze can be toxic . Never dispose of toxic anti-freeze in
open water .
• Make sure that the cooling system is filled with a suitable anti-
freeze liquid.
• Disconnect the batteries, fully charge them and grease the bat-
tery terminals. Store the batteries in a dry and frost-free place.

• Check for coolant leakage
• Check that all cable connections, bolts and nuts are tight
Every 100 hours, at least once a year
• Check batteries, cable connections, bolts and nuts
Every 500 hours, at least once a year
• Control flexible motor mounts
• Check for coolant leakage
• Check cable connections and fasteners
Every 1000 hours, at least once every 2 years
• Replace coolant (with keel cooling)
10 .1 Raw water cooling
• Close the seawater shut-off valve.
• Remove the cover from the raw water strainer.
• Clean the raw water strainer if necessary.
• Connect the raw water inlet to a fresh (drinking) water pipe or to
a tank with fresh water. Open the tap and let the cooling water
pump run for at least 5 minutes to remove salt and contaminants
from the raw water cooling system.
• Stop the pump and close the tap.
• In areas where the temperature can drop below zero during the
winter, the outside water system must be protected. Pour 1 liter of
anti-freeze (preferably a non-toxic biodegradable anti-freeze) into
the cooling water filter and run the pump until the anti-freeze is
incorporated into the cooling system.
• After cleaning and mounting, check the seal between cover and
filter housing.
If the lid is not properly sealed, the seawater pump sucks in air. This
can lead to an excessively high motor temperature.
10 .2 Keel cooling
To prevent damage, the cooling system should be filled with an anti-
freeze/water mixture (or coolant) during the winter months.
N.B. Replacement of the coolant is only necessary if the coolant pre-
sent in the cooling system does not provide sufficient protection
against temperatures below 0˚C (104˚F).
10 .3 Electrical System
• If necessary, regularly charge the batteries during the winter!
• For checking and maintenance of the batteries, follow the recom-
mendations of the battery supplier.
