I have a 1998 Sea Doo Challenger 1800 with dual 787 motors. Both are having the same idle issue….I have a high idle speed of 2800 PRM and cannot get it lower. The throttle linkage is set according to the manual. It is resting on the idle speed set screw. If I back off the idle screw, the linkage will only go so far and not touch the screw. I have slackened the throttle cable and that doesn’t seem to matter….. It is going to, I presume, it’s fully retracted position. How do I get the idle speed down?

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?
