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 4mm nut driver and 2.5mm hex
wrench to remove the two screws that
secure the rudder to the rudder bracket.
Move the rudder aside, but do not
disconnect the rudder linkage.
Raising the drive helps eliminate oscillation or
bouncing and assist with top end stability but
excessively raising the drive can reduce top
speeds and cause cavitation.
Use a 3mm hex wrench and 7mm nut driver
to loosen the bolt that attaches the output to
the bracket to adjust the height.
