After having our throttle and steering cables replaced because of of sheath craacking from exposure and tuned and winterized at dealer we have a too fast idle issue.We barely have to chock ig go start and its idling at 1100 after its warmed up stayed at 1400.thats too fast.we tried the idle set screw a d that didnt make much difference.we never had any problems like this before so am thinking it's the throttle cable.any advice on what to do?

Most likely the lowest "set" position on the throttle cable is too far advanced. Not sure about your cable--but most have an adjustment, so it will go all of the way down. Your having worked with the idle screw setting and not solving the issue would confirm that. There may adjustment at both ends.

What outboard do you have? What set of cables did you use? (Teleflex?)

Its a 2006 honda 90. I do not know what kind of cable was used.Is adjusting this a difficult thing to do.we are trying to avoid having to pull a loaded boat out to take it back for them to adjust it if possible.However we also don't want to mess it up more.

Ever adjust a motorcycle brake cable? Bicycle brake cable? Exact same principle.
Google adjust honda 90 throttle cable?? https://www.youtube.com/watch?v=JAFCOnTS9_Y

You don't have to pull the boat out to adjust the cable end fittings. I no longer have a manual for the Honda 90, but I looked in the shop manual for the 150, and it appears to have the same binnacle for shifter and throttle. At then end of the throttle linkage--near fast idle lever, there is adjustment for the throttle linkage. There is a brass threaded rod on the end of the cable, a lock nut and then the terminal piece of brass, with the hole which goes to the pin. That terminal link, should have a little slack in it. If there is no slack--then it is pulling the throttle cable terminus on the engine, to a faster idle. You should be able to adjust the throttle cable at the engine throttle plate also, with the same mechanism that you can at the binnacle.

My guess is that whoever installed the new cable did not properly adjust these linkages and the cable is pushing the idle up.

And why would you take it back to a shop that cant do a job right. I would tell them to get over to your place and fix it. Part of installing a new part includes tuning it correctly. its a very easy thing to do your self . if you are lowering the idle screw and the rpm is not dropping you should be able to see space between the set screw and the stop because the cable is not allowing it to reach the stop.

yes we saw the screw backed off and wasnt touching.we are not sure the proper procedure for adjusting the cable.not real comfortable with getting into the throttle at the helm.can this be fixed at the attachment at engine. Forgive my ignorance.i'm sure its easy when you know what to do.

Very little adjustment at the helm. Lots of adjustment at the engine. With the throttle lever in NEUTRAL, engine cover off find the cable attached to the throttle linkage. Follow it to where the cable housing(gray plastic covered part) is attached to the engine bracket, there will/should be two 8mm,5/16 nuts locking the cable housing to the bracket, loosen the lock nuts, move cable housing closer to linkage. If you get frustrated drive to the place you had the work done, grab the owner by the neck, take him to the boat & make him fix his shitty quality control. Wink Rolling Eyes Beer

The plastic piece that snaps over the ball stud on the linkage is also adjustable & has a lock nut. There is also as DR. Bob said, a similar set up & some adjustment at the throttle lever end. After you are done make sure with the throttle pushed all the way forward the engine end will go to wide open throttle (engine off). & return to idle (650-700rpm)or so.
Have a good one!! Mr. Green

well i guess we are just dumb.we were not sure what to do.cables come into engine on portside to an assembly with screws then transverse to starboard side below the carbs 2 more sets of screws so didnt know what was to be adjusted.i guess we will see if either a local mechanic would do it(hopefully in the slip) or might have to make the other original shop make it right--anger they should but also not as much confidence on the work quality now. Grrr. Thanks everyone. To bad your all so far away!

I was too generic with my description.
Remove this R clip, screw the piece the R clip goes in, up or down the cable, making it longer or shorter as nec. Beer [/url]
