I replaced the steering in my boat because it was time. The shop wanted $3500.00 to put there steering system in. Went home and got to looking and found this steering system. Got it, installed it in my Proline 230 center console with a Mercury 225 optimax in under an hour. I have used other steering systems that cost 7 times what this system cost me and they are not as smooth when turning the helm. There is no lag, no sticky feeling, it is very responsive. It has been on my boat for a year now and there are no issues or complaints. The instructions are very simple and easy to understand (if you need them). Other than the labels and the difference in feel, there is no difference in materials from the high dollar system to this one. If I need another one in the future I will come right back to VEVOR!
