(as necessary, according to the floating area)
All you need is a regular inspection.
Seawater dynamically cools the seal as the yacht moves, the water passes through the engine seawater filter.
We recommend you to consult the instruction manual supplied by the Manufacturer.
CAUTIONContinuous navigation at a low speed, both forwards and backwards (such as for fishing), can cause the seals to overheat and, consequently, their irreparable damage..
CAUTIONAt least once a week check for water penetration.
At least once a month carry out the cleaning.
Periodically:
- Check the status of the seals;
- Check the compression of the seal and when necessary carry out the compression.
- Check and service the cooling circuit of the seals in order to prevent dirt, seaweeds and foreign bodies from blocking the cooling water flow, thus causing the seals to overheat and, consequently, their irreparable damage.
(as required according to stationary area, but at least every month)
The outer support arm includes a Neoprene bushing which uses the sea water as a lubricant.
The Neoprene bushing, during navigation in waters with sandy suspensions, may wear rapidly. The bushing wear causes a vibrations increase.
With the yacht in a dry shore, a good technician can easily evaluate, by moving the shaft, if the wear is so bad as to need the bushing to be replaced.
(as required)
We suggest to clean periodically the suction strainers for the seal cooling.
Cleaning depends on the conditions of the sucked waters (seaweeds, mucilages, etc.).
Before removing the filter, it is necessary to close the valve fitted in the sea cock, to prevent flooding the bilge with water.
A spare propeller shaft should always be kept on board (an housing for a spare shaft has been arranged in the engine room, the shaft can be removed from the aft transom).
