Lubricating the Flex Shaft
Lubricating the drive system is vital to the life
of the drivetrain. The lubricant also acts as a
water seal, keeping water from entering the
hull through the stuffing box.
Lubricate the drive shaft, propeller shaft
and all moving parts after every 2–3 hours
of operation.
 1. Use a thin 8mm open end wrench to
remove the brass ferrule from the lower
end of the motor.
Note: The threads on the brass ferrule
are reverse threaded. Make sure to
review the photo before removing the
ferrule.
 2. Carefully remove the brass ferrule from
the lower end.

Checking the Steering Cables
It will be necessary to check the steering
cables to make sure they have not stretched
over time. Loose cables may cause your boat
to wander right and left and make it difficult
to trim.
 1. Check the steering cables, making sure
they are tight and the steering is slop-
free. Use needle nose pliers to tighten the
nuts against the clevis to keep the cables
from vibrating loose.
