Hello,
Not sure if this is where to post this, but I didnt see anywhere else that made sence either:)

Anyways, I have a 2000 Nitro 750 w/Mercury 90 with rack and pinion steering. I may upgrade to a 135hp mercury in the future also. I want to upgrade to hydraulic steering but not sure how to determine what will work with my boat. Only thing I know for sure is to measure the length of the existing cables to figure out the length of hoses that will be needed.

This is what I am looking at to buy.....if it will fit and work.
