Re: Yamaha 9.9 Throttle and Gear cable adjustment guide?
I'm not familiar with that model but I just converted my Y9.9 to the 703 remote. At the engine connection the cables have to be adjusted just right for the gears and throttle to work. Mine were high idling/revving on the first try. Try adjusting those nuts on the cable at the engine. If the cable isn't exactly putting it in neutral then you can't shift.
We don't need no stinking badges.
