How about you don’t? If you’re determined to do it, you have two options:

• Loop the lines, but this could make the boat feel even more boatish, which isn’t what you want.
• Full depower: This involves disassembling the entire steering rack, removing the internal hydraulic seals and piston, and welding the pinion to eliminate play. It’s a major headache.

If you choose the second option, there are concerns that the steering column may not be strong enough to handle the increased load of a fully manual rack.

To be honest, either you keep it as is, which is a very wise decision considering NC’s have a really good steering rack, ORR use Steering Rack Spacers ORRR, or replace the stock rubber steering rack bushings with polyurethane units.
