What is being called a “yoke” here is actually your collar steering fork.
It will have a grease fitting at the top of it’s shaft.
The collar steering fork shaft is ported. The port directs grease to two areas; ..... one to a circular grove for the upper plastic bushing, and one to the circular grove for the lower plastic bushing. The circular groves ensure that the grease is spread out within the complete ID if the bushing.
These ports (not the circular groves) can easily become clogged up with old dried out grease (people fail to routinely lube this area).
The fix:
With the collar steering fork not yet installed, place a hose clamp over one port (plugging the port) and and pump grease into the fitting. The open port will clear itself out.
Do the same to the other port!
Now the grease ports are clear and will direct new grease to the bushings!!!!
If grease is oozing out on to the helmet, the V-ring seal is most likely bad and must be replaced!
I suggest gluing the new V-ring in place onto the collar steering fork.
Be sure to grease the V-ring lip so that it can freely rotate against the transom shield surface.
Note:
No-feed-back and/or hydraulic steering is great..... however, each “masks” unwanted steer torque! This means that the helmsman may not feel the torque, but it is still there causing premature steering component wear.
Point being...... do your best to adjust the trim fin/torque tab as to eliminate this steer torque! See your OEM service manual for a suggested setting.
