Cabin Ports
The ports are made of acrylic and are highly impact resistant. However, avoid highly abrasive
cleansers which can scratch them. Instead, use mild soap and water to clean ports. Avoid
chemical solvents, notably acetone, which can "melt" the ports...i.e. smear its smooth finish.
DO NOT PERMIT ACETONE OR TEAK CLEANER TO GET ON PORTS OR HATCHES AS THEY WILL
DISINTEGRATE AND “BLUR.”
Stainless/Chrome
Salt is an extremely corrosive element and whenever possible owners should spray all stainless
and chrome deck hardware with a healthy amount of fresh water after sailing each day.
Hardware like the pedestal guard, stanchions, handrails, bow/stern pulpits, and winches can be
treated with Never-‐dull® or other light cleansers. After applying cleanser, polish to a gleam with
a clean cotton rag. For more aggressive cleaning a product called Wichinox (made by French
company Wichard) has been highly recommended for cleaning and protecting SS.
Optional Wheel Steering System
Your steering system is the most important system on board your boat
As with all mechanical systems used in the harsh marine environment, proper inspection and
maintenance is required for long life and years of proper service. Systems that have not been
maintained and lubricated properly may show signs of wear early and perform less than
satisfactory. Therefore, it is important that all boats fitted with wheel steering systems get an
annual inspection of the critical system parts and that routine maintenance guidelines are
followed.
Jefa Rudder Bearings & Gaiter
Bottom Bearing
-‐ The bottom bearing doesn't need any maintenance except for a good hose down
when the boat is taken out of the water. The main reason for this hose down is to remove the salt
water out of the bearing housing so it can't crystallize. If the shaft rotates irregularly, it could be
that some rollers have developed a flat side.
The exchange of the rollers is quite simple: Lower the rudder out of the boat. Remove the thin
Delrin ring holding the roller track. Now the rollers and roller track will fall out. Mount the new
rollers. To ease this job one can apply a film of detergent (soap) to the inside of the bearing
housing, so the rollers will stick (NEVER use any grease). Mount the bottom roller track again
and clip-‐in the newly supplied Delrin ring.
Top Bearing
-‐ The top bearing doesn't need any maintenance. Unless the bearing is exposed (no
deck cover present) one should yearly hose it down to wash away any sand and dust between the
rollers and the housing.
Gaiter
-‐ Gaiters should be inspected yearly for mechanical damage. Carefully inspect the complete
gaiter surface if any cracks are present, especially around the clamps. If you don't trust the
sealing capabilities of the gaiter any more, replace it with a new one. Gaiters can be supplied in
unglued state, so the rudder shaft doesn't have to be dropped. Bend the new gaiter around the
