Yamaha 704 Binnacle Mount Throttle Arm Upgrade - Fix sticking/sticky throttle control

[@ap4802]

I was having same issue, but quickly figured out it was the shift linkage at the motor. Specifically, under the powerhead where the linkage attaches to the shifting rod. Not sure what motors you have, but mine are 99 F100TXRY models… older models have a tendency to rust at the pivot point, under the powerhead. Appreciated your video because of the internal workings of the 704 Control Box.

Thanks !!! My 704 is also very stiff and clunky. Now I know I can disasemble and clean and lubricate thanks to you!

Thank you so much man helped me a great deal

Also, the peanut butter colored grease was factory. If you’re still having issues with the throttle, the issue is going to be at the shift rod assembly, under the powerhead.

[@ap4802]

One of the ways you can quickly confirm if your issue is at the shift rod assembly is by disconnecting your shifting cable at the motor and manually check function of the shifter. You should be able to manually move it with your fingers. If you can’t, shift rod assembly will need some heavy duty lubrication.

Thank you

Yamahas shift gears by rotation, meaning when you engage the gear, the shift rod rotates to shift it in gear. If the shifting rod is binding, the issue will be in your shift linkage, and not in your control. Guaranteed. Yamaha 704 controls rarely fail.

My throttle is loose and it won’t throw cable to idle

[@barronc]

Great video. Can you explain how you ruled out the throttle cable? Mine is very sticky in and out of gear, once you get in gear it isn’t too bad.

I pulled the controller and disconnected the throttle cables and was able to easily move them by hand. When I first started to fix this issue, I was convinced the throttle cables were the problem (20+ years old), so I bought a cable lubing device (search 'cable luber' on amazon) and was planning to lube the cables. Once I removed the controller and played around with the cables, I realized they were not the issue since they moved freely with little effort. This lead me to digging into the controller and playing with all the mechanical pieces of the assembly.

just found your video on the 704. I have a 10 year old Yamaha control that is also hard to shift,sems like throttle is ok. was wondering before I attack this how hard it is to release the cables at outboard motor end to see how well they slide. thanks John

very easy

The throttle friction band is not suppose to be lubricated. You can remove the lubricant with solvent, however only allow solvent to contact nylon parts momentarily or it can cause them to expand slightly and not fit properly.

[@IIcrackerII]

Good to know. There was clear evidence of old white lithium grease in there that looked factory.

[@davecindw]

You need to replace the throttle cable

[@IIcrackerII]

I had initially suspected the throttle cable, but it is not the issue here. I tested the cable by isolating it and ensuring it was not hanging up.
