The service manual suggested reduction of gear teeth is instead for the aluminum "throttle sector gear" which engages the remote control cable's nylon rack gear (unlike vintage OMC remote controls where the nylon gear is part of the remote control, Mercury included the nylon gear with their control cables). This was a production change, and then only required when (if) utilizing the earlier remote control cables utilized with KAMINC/Quicksilver 2-lever controls (these have a 13 tooth nylon gear), in these single lever Quicksilver controls. As you have the correct control cables intended for your control (with 17 tooth nylon gears), the change/reduction of gear teeth for the throttle sector gear is not needed. You already have enough travel for the "throttle shaft & link" except that you (or who installed it there) have the "warm-up" lever incorrectly indexed" (it can theoretically install in four positions), being 90 degrees off, and therefore limiting it's full travel.
