Re: remote throttle box shot? throttle cables junk?
As bonz-d said, the 77 has a clip on the throttle, and the 84 uses a nut the same as the shift on both years. But the "Casing guide, control housing", the remote end of cable, part # 206408 and the "Casing guide/O ring assembly", the motor end of cable, part # 385956 should be the same. I am including a photo of a 77 Power Pilot (remote) cable pair and a photo of the motor ends of cables. Minus the clip on the one cable, these cables should be the same as the 84.
Match them both!!!!!!!!!!!!!!!!!!!!
Compare these to yours, if they are the same, than you only need to figure length of cable.
This is an unserviced cable set and remote so excuse the filthy condition of the parts. Easier to get to than what is installed on my boat, these are in my shop.
what am I supposed to match, the control box or the outboard? hell I was thinkin you had to match the motor.
