Replacing the grease cord of the propeller shaft is not a difficult job and I will describe step by step below.

If the grease cord needs to be replaced but the boat is still in the water, this is no problem. A gasket holder usually contains 3 pieces of grease cord, if you replace 2 and leave the last one, hardly any water will enter the boat when replacing two strands of grease cord.

 

Step 1.
Loosen the two nuts completely (sometimes a lock nut is used which must of course first be loosened).


Step 2.
Slide the flange towards you so that the propeller shaft is released.


Step 3.
Remove the old grease cord, if the boat is still in the water then no more than 2 so that the water does not enter.


Step 4.
Place the first piece of grease cord around the propeller shaft and cut it diagonally on the shaft so that the ring closes nicely. Now slide the ring between the opening around the axle. If it does not fit properly, squash it with a hammer on a wooden board. Push the cord in with a small screwdriver.


Step 5.
Slide in the flange by hand to push the cord back as far as it will go.


Step 6.
Then place a second ring, with the opening staggered from the first. If successful, place a maximum of three rings. Make sure that the flange can still slide in sufficiently (minimum 5 mm).

Cut the fat cord.

 

Step 7.
Then tighten the nuts left and right equally, so that the propeller shaft can still be turned easily by hand (I always use a caliper for this).


Step 8.
Apply the grease with the grease gun or grease pot. It may come out something.


Step 9.
After 10 minutes of sailing, stop the engine and tighten the nuts a little more. Will not be more than a hit, then grease again and it should be able to withstand another month.


Step 10.
After a month retighten slightly. You can see it when some more water droplets come off.

Three strokes with the grease gun after each boat trip is more than enough and use grease that is lithium soap based and you can buy it in the webshop of this site.

Gasket presser.

 

What should you pay attention to.
The most common mistake made with grease cord seals is over-tightening. As a result, the grease cord heats up and the seal will leak more. Secure as little as possible and especially not so tight that the axle rotates heavily. Grease cord seal is always leaking something.

In addition to the above gasket presser, you also have the floating inner bearing, which is attached to the propeller shaft with a rubber sleeve.

Packing gland with rubber sleeve / floating inner bearing.

With this type of system it is important that stainless steel hose clamps are used to clamp the rubber sleeve on the propeller shaft sleeve and the gland.
The rubber sleeve does not last forever and should be replaced prevention and always use new hose clamps. Rubber sleeve can be found in the webshop of this site.
