Before installation of gearcase on motor, shift rod adjustment MUST be checked. Refer to SHIFT ROD ADJUSTMENT on p. 290.
SHIFT ROD ADJUSTMENT
Check the shift rod height from the shift rod hole to the surface of the gearcase using Universal Shift Rod Height Gauge, P/N 389997.

With the shift rod and detent lever in NEUTRAL, rotate the shift rod up or down as necessary for correct adjustment. Once correct height is achieved, rotate rod one half turn or less to face offset forward.
The NEUTRAL detent is a two step design. Make sure the NEUTRAL detent ball is in the center step before checking shift rod height.
