Hi Everyone....I have been trying to adjust my throttle cables so I can get the boat to idle properly. It is currently idling too high(around 3000RPM in water)....I follow the instructions perfectly and it idles too high....when I try to back out the idle screw, the linkage will sometimes not touch the idle screw?....so I make sure I have enough slack so that it will, but sometimes the linkage doesn't snap back....it will snap back fine by hand....The procedures I use are the ones in the manual....The cables are three years old...is it possible that cables need to be replaced?

Looks like you asked this question some time ago, with no response, so I'll try to help.

The spring in your carb's throttle plate is what takes up the "slack" in the throttle cable when in the throttle shifter is in the idle position.

Many times when people have problems getting their throttle cables to "rest" properly, it is usually due to seized throttle lines, not having the carb throttle synchronizer adjusted properly, not providing enough slack in the cable at the throttle shifter (you can add more slack in the cable @ the shifter), or a seized/damaged carb throttle spring.

I would suggest first removing the carb synchronizer, and then verify if the cable fully retracts back to the idle screw. This is quick and easy to do. If the throttle still appears to be sticky then my next steps would be to check the carb throttle spring, and then the throttle shifters.

Additionally, if you're NOT running premix, you may also take a look at the oil pumps. The throttle linkage on the pump may also have an impact on the slack in the cable.
