Propellers and Shaft Lines: Maintain and repair to avoid changing

If each supplier has its own recommendations, the maintenance of a boat's propulsion line has some essential steps. When the boat is taken out of the water, the yachtsman should check the different elements: propeller, shaft line... as explained by Ayoub Tebaï from France Hélices. "There are common things to see every year: we'll visually check the clearances in the bearings or hydrolubric rings, the bearings the different wear parts."

To avoid unpleasant surprises, it is advisable to change certain wearing parts regularly. The stuffing box packing or the lip seal, according to a regularity which depends on the shaft sizes and the sealing system. France Hélices reminds : "On small boats, we tend to recommend it every year, taking advantage of being out of the water. It also avoids wearing out the shaft if you've overtightened it. In any case, cleaning is a must."

The anode is another important part. After cleaning, a visual check of the appearance and potential damage due to electrolysis can be performed.

The propeller can be repaired and maintained. Professionals such as France Hélices are able to repair and reconstitute a damaged blade, whether it is a copper-aluminum, stainless steel, aluminum or brass propeller.

In addition, it is advisable to have the propeller balance checked every 4 to 5 years by a professional. This will prevent any imbalance from damaging the shaft when sailing. Replacing it would add considerably to the bill!

In conclusion, prevention and regular controlled maintenance with professionals can avoid many setbacks, confirms France Hélices : "Saving money on hydrolube bushings, it's ultimately the whole shaft line that has to be changed and the boat that is immobilized in the middle of the season!"
