I agree with Harpo, not having hydraulic steering isnt the end of the world. I ran my 882 for 7 years without it and i naver had any problems. What i did to make it a little nicer was installed a no feedback helm and it made a huge difference in the torque. The nfb helm was a nice to have not a requirement, i never had any trouble holding on to the boat when it had the regular steering. I do think Glenns advice is good, drive it. If you dont like how it feels you dont have to buy it.
I agree with everyone that hyd steering is nice, i have it on my z7 but i would have no problem buying a boat with cable steering again.
