I have a 1991 Proline with 200 hp V6 outboard w/ 9.9 yamaha 4 stroke kicker. Everything worked fine when I put the boat away in February. Last month, cleaned everything up and got her cranked, no problem. Put in the water and couldn't get the main throttle to advance beyond halfway all day. We were limited to about 10 mph, but made it work. Started up the kicker, but could not get it into gear. I took the cover off the control box and found the "black retangle shaped" piece that moves up and down to translate the throttle movement to the cable, to be stuck in the down position on the kicker motor. I'm pretty handy, but haven't done a lot of boat repair. Any help would be greatly appreciated. My wife says we can't afford any boat repairs right now......:
