P/N 27720 Detent is a shifter bearing assembly upgrade made by OMC in 1991. Upgrade as listed below OEM 915954 Will allow shifter rod assembly to find center of forward and reverse location. The old version had 1/8 inch or more play when moving shifter rod in neutral location. This now allows the installer to measure base to top of rod end receiver. Upgrade has built in tapper lead on both side of detent. This allows shifter rod to go into forward and reverse gear with about 7 to 10 lbs. Old detent shifter rod was about 15 to 20 pounds to move rod. Modification now places less pressure on shift cable. Less wear on clutch dog and forward gears as shift cable sides in and out of gear easier. Shift cable life expectancy with modification will last longer with 10 pounds less pressure on metal cable when changing gears.
