Stumped on removing Quicksilver Throttle/Shift Control Handle 1986 Seville

[Forever Fixer]

I'm a newbie on this forum thanks to my college age son's purchase of a decent running 1986 SR Seville II two weeks ago. We're currently in the process of rebuilding the interior to his satisfaction. He's making good progress having recovered and rebuilt all the bow seating. We're now working on the main cabin but ran into a snag. We can't figure out how to separate the shift/throttle lever from the control box. The nameplate was missing but I believe it is a "quicksilver" controller. We found a quicksilver 3000 disassembly instructions but it seems to be different. There is a black plastic piece that is depressed during "Throttle Only" mode but it doesn't seem like it comes off. Any help would be much appreciated!

Are you USA?
The center plastic comes of gently , behind it is a bolt or nut . Remove that and the
Handel should come off.
Some models use an allen grub screw in the bottom of he handel

Thank You for the reply! It's good to confirm what are intuition told us. It didn't come off easily with a pair of needle nose pliers so I will try to pry it out with a dental tool tomorrow and report back. I also discovered that the black plastic piece has been smashed in somewhat over it's 30+ year lifetime preventing the "Throttle Only" mode button from working. The button still engages using a nut driver so we'll need to makeshift something else to get back the function. I thought I would go ahead and clean the mechanism on the bench and lubricate it well before installing it back in the boat with the new side panels my son is fabricating.

Good News. I was able to separate the handle from the housing. It was held in place with an allen screw in the bottom of the handle. I destroyed the plastic "throttle only" engagement push button in the process of my poor disassembly but I needed to do something with that anyway as it was not engaging. Wow. Talk about an impressive mechanical mechanism married with some innovative clock spring wire routing for the stern drive control wires! Now the challenging part, Cleaning, lubrication, and reassembly!

Thanks again for the help.

how did it all go? I am dealing with the same controller. Just a 1988. Having issues separating it from the wood.

If it is similar to ours, you should be able to use an allen wrench to remove the set screw holding everything in place. If you look at the last pictures I posted on this thread, you should be able to tell where the wrench goes in. You may have to pry back your vinyl trim a little to get access to the hole.

Our 86 is back on the water and getting good use having completed the restoration. It looks good with all new interior vinyl and carpeting & a used wake board tower. The little 4 cylinder is running well and pulls a wake boarder no problem. It has about 35 hours on it since the rebuild. The biggest pain of the whole process was pulling the motor and fixing a major engine oil leak on the rear main seal and oil pan gasket. My son is having a lot of fun with the boat and it's been a good overall experience working on it together.

Good Luck on your build!

I have a 1988 SeaRay Seville, 4.3 merc alpha 1 with a quicksilver control. The same as shown here. How do you disconnect the throttle cable from the control unit. I need to replace it Sonics the cable broke.

I joined just for this post! New to boats myself and still learning. Decided to re-do the boat interior (93 bayliner), similar throttle control unit (gen 2), Same hex bold on the bottom i believe, mine looks like something is blocking between throttle plastic and allen bolt. Is there any specific position the handle needs to be in to get clear access to this bolt? And do you recall the size of the Allen key?

my 1988 Searay was / is missing the shift lever set screw. I tried a regular set screw but no luck. Threads in fine, but does not hold the lever steady. Any one have picture of the correct one or part number. Thanks

Does anyone have a diagram for this throttle control I took mine apart, and I can’t figure out how to put some of these pieces back on for the idle control

Sent you a link to download Mercruiser controls, old and new, from my GoogleDrive.

It is too big to post here

Sent you a link to down load the manual, also.

This thread is 3 years old. Probably ought to start your own so you can keep track of it.

Delete. That was 3 year old thread.
