Should the stuffing box continue to leak after tightening down the gland nut and after several hours of
engine operation, a new stuffing box packing may be necessary.
The Teflon-coated asbestos packing can be replaced by unscrewing the gland nut and winding three
turns of 1/4" tallowed flax packing around the shaft in the direction of the nut installation. Replace the
gland nut again and tighten just until the leak stops, and finally tighten the lock nut. Should any leaks
still persist, a bent or scored shaft may be the problem and should be investigated.

Propellers
NOTE: Depending upon which type of propeller is fitted, at fit-out check that all split pins through
retaining nuts are in place and are sound. (see table 9)
A two-bladed, solid bronze propeller is standard on your yacht. This unit is the better choice for cruising
purposes. For racing sailors, the optional folding propeller is superior, offering the least amount of drag.
5.5.1
Installation of Propeller
Ensure the base of the propeller is free from dirt and any corrosion. The end of the shaft should be
cleaned and any burrs on the shaft or keyway must be removed. Place the propeller on the shaft with
both propeller and shaft keyways in line.
The key should fit tightly at the sides but with a 0.1" (2 1/2mm) clearance at the top. Do not force the
key in since it may shift the propeller off center.
5.5.2
Propeller Alignment
Ensure proper propeller alignment which can be checked by clamping a piece of metal or wood to the
propeller strut which just touches the edge of one propeller blade. When rotating the shaft by hand any
variance in the track will be noted by either striking the indicator with the next blade or showing a gap.
If the propeller indicates such a condition it should be checked and balanced by your dealer or any
marine yard familiar with this type of work.
5.5.3
Removal of Propeller
For both solid and folding propellers, a propeller puller is required which can be purchased at any
marine dealer.
Procedure for Removal of a Martec Folding Propeller
