When your boat creaks and squashes and lurches around at sea, chances are your yacht‘s propeller is damaged.
At this point, you don’t need to panic too much, because there are still remedies. Follow these simple steps and the problem will be solved.
First, to confirm the degree of propeller damage to ensure that the failure, the boat is located near the water without shallows, tree stumps, rocks and other dangers.
If you see an oil slick around the stern plate, this indicates that your gearbox or propeller shaft has been damaged so badly that oil is leaking out around the propeller shaft seal.
If possible, Replace a broken propeller A bent propeller can throw the boat out of balance, and even a slightly twisted propeller can sway the boat, causing potentially serious damage to helical shafts, bearings, seals, and gears.
If the propeller is still strong enough to keep the boat idling, and if there is a dock or safe place nearby where the boat can be parked, you need to steer the boat there.
In this way, when the boat stops safely, it will be more convenient and safe to replace the propeller.
Even if the blade does not seem to be damaged, do not think that there is no problem with the propeller.
Collisions with sandbars or hard mud bottoms can also throw your propeller off balance and tilt.
Under load, the propeller axis will continue to become flexible, and at some point the entire propeller will be lost.
Don’t forget to bring the spare thrust washer, which is fitted between the propeller and the gearbox, the propeller nut, the cotter or lock washer, the propeller wrench, and the vise for pulling the cotter.
It is best to use a plastic propeller wrench because it floats.
