I have a 1998 175 EXECD Evinrude Oceanpro and I have a problem with a sticky throttle.
I have replaced the throttle and shift cable and have just installed a new BRP control box and the throttle is still a bit sticky in the last 30% of the lever travel.
I have taken the engine cover off and looked at all of the carburetor linkages and timing advance lever and have narrowed down the issue to a small short plastic bearing that moves the timing lever at the top of the motor that advances the timing and the tall thin plastic bearing on the carb actuating arm. Both of these bearings move or are moved by a piece of curved plastic.
Has anybody heard of this or these parts causing an issue? I use this motor on a 17ft ski boat and it is increasingly frustrating trying to get a smooth change in revs when a skier is behind me.
Any help will be greatly appreciated.
