My 52’ 3100 with a 59’ 235 installed, did not come with a throttle cable installed. Although I have yet to install one, I did look into how it is done. Basically the cable passes thru the throttle rod taking the place of the cotter pin with the cable stop just below it. That allows the cable to pull up the throttle and also allows the throttle to slide up the cable. This is shown in the Assembly Manual page you posted. The sleeve or guide that you mentioned is actually the cable stop that is clamped to the cable with a screw.
