Suitable helm replacement??

[gofish]

Hello All
Just found this great forum and was hoping someone would have the answer to my question:
I have a 1985 V-20 Steplift w/ mid-90's 150 Yamaha. The steering went out on me Sat., 8 miles out in the gulf. I've determined that it is the gears in the helm that are broken. At first I still had port steering, only the starboard steering was out. Somewhere between the slow trip home the port steering went out as well.
My question: Is this http://www.outdoorsuperstore.com/pro...sp?prod=254135 a suitable replacement for my current setup. I'm almost positive it's the original helm that I have now.
Any advice or links to other products would be greatly appreciated.
I'm not looking to go to hydraulic or upgrade to something that I don't need. I just want my steering back on my beloved (and well-used) v-20.
Thanks
Ragan
