When you order the new cable kit, also order Teleflex part number SA 39329.

This is a tilt tube cable seal for an outboard, it will screw directly to the end of the steering tube on the outside of the TA.
Do not grease the hell out of the cable before using the boat, this will actually draw water in as the cable moves in/out by creating a suction when the tube moves back and forth.
Best case scenario is to grease the cable slightly after use. But I don't like the grease fitting at the rear, but at the helm.
Use a lithium based grease on the tube end but very little. This should be disconnected and cleaned at least once a season.
Hope this helps...
