Steering shot -aftermkt replacement

[sven]

launched today and my steering went. You needed allot of force to turn the wheel last season so I new it was going. Needed to hard turn when docking today and it finaly went (i put alot of force to turn and you could feel it strip -so the steering wheel now turns and the OB doesnt move). Can i replace with one of those steering replacement kits (around $180)? And how easy is the job? My boat is a 1986 V20 w/150 1986 proV Yamaha.
