I have a 2005 Yamaha 115 4 stroke mounted to a 20 foot center console. At anything above 2000 rpm I find that the throttle will "vibrate" down to an idle speed. This causes me some concern as I must always keep one hand on the throttle and drive the boat one handed. Is there any way to adjust the tension on this control box so that I wont always find it going to an idle speed??

It's a relatively simple fix. At the base of the plastic housing are four screws. Remove them and gently lift the housing away. With the cover removed you will now see a slotted screw at the base of the throttle handle. The screw adjusts the tension on the handle by screwing it in. Do it in small increments until you have the desired results. Good luck. -
Great, thanks. I will try it!!!Comment
