Not sure what you are specifically looking for in terms of advice. Seastar is obviously the best of choices. I upgraded my 2005 208 years ago to Seastar hydraulic after the original steering froze up on me and it was a significant improvement in steering. The one thing that i do recall is that the old mechanical steering could no be removed 'cleanly' without the engine coming off - the cylinder of the assembly was too long to come out. Instead of going through that ordeal (it would have been an ordeal at the time) of hoisting the engine off, we popped an inch and quarter (or so) hole on the stbd side wall of the motor well, which gave the cylinder enough room to come out. I can't tell you that you will have the same issue, i'm just conveying what I remember of my challenges.
