Quicksilver Throttle Issue

[Doug Roy]

I've owned this 1992 22' cruiser for a year now. It has a Quicksilver steering wheel and throttle/shift controls but a Volvo Penta engine and outdrive, so the original MerCruiser power plant was replaced prior to my purchase. My problem is with engine throttle control. Both throttle and shift cables are brand new. Shifting is nice and smooth with no problems, but on the throttle there is a "no man's land" between about 1,400 and maybe 3,000 rpms where the throttle lever just doesn't want to stay. It wants to fall back to the 1,400 position anytime I release pressure. Engine throttle does NOT stick. I get immediate response to any throttle lever movement. The control just applies strong pressure back and will not stay in position upon release until you reach around 3,000 rpm's. From then on it adjusts nicely. Same deal coming from high power to low. As soon as the rpm's get down under 2,500 the lever wants to "pop" way down and put me back at about 1,400 rpm's again. Throttle adjustments at the carb are free and smooth. What could be going on in the Quicksilver control mechanism that would cause this? Is it worth trying to fix or should I just replace it?

I don't know the model number but here is a pic.



Thanks!

Re: Quicksilver Throttle Issue

Its is worth fixing and their is nothing wrong with it at all. The issue can be solved with I believe with a adjustment of whats known as the friction lock most all controllers have this.. What your describing often happens and it has a adjustment to add a fit of friction to stop it from dropping or moving and make it stay in place. I am not sure where the adjustment is on that controller. I read in a thread some time ago that it has a internal adjustment screw and I believe thats known as a commander controller. If you have a mod move this over to the merc section or start a new thread there I am sure the guys can help you get it sorted out. I will look into it a bit my self and see if I can find the thread.

I looked it up in the merc controller manual I have and it is shown as a comander console mount control. I havnt found instruction on the adjustment but it dose show a screw called the Throttle friction screw item # 29 on the parts drawing. I will see if I can post the drawings.

this is the best forum for the thread mh, as its not a motor related issue.

ill pm don and bondo

If you take the plastic cover off, there are set screws at the top of the unit for throttle tension and shift detent pressure. As I recall, the one on the left is throttle tension friction. Just tighten it for more pressure.

Thanks to all! Great input. The screws are right where Don said and work as described. The throttle "brake" adjustment screw was all the way backed out so no brake was being applied. Engaging the throttle brake appears to help significantly. The design is odd though. I see the slot for neutral. Putting the boat in forward takes it out of this slot, but as you increase throttle a small amount another slot is encountered where it wants to "lock" in that position. I'm sure that my 1,200 - 1,400 rpm "stuck" spot. Increasing throttle beyond that point requires the same amount of pressure as putting the boat into gear. That doesn't make sense to me. With the brake applied I think I'll see improvement, but what I'd really like to do is eliminate that second and seemingly useless slot. Any further thoughts are appreciated.
