When all three gears need to be replaced in your V6 Johnson / Evinrude Outboard the installation of the new GLM No. 22666 heavy-duty gear set is highly recommended. The heavy-duty gear sets can be used with all V6 outboards from 1979-2006 with the “O” type gear housings. It is recommended that the new clutch GLM 700-22625 also be installed with the heavy-duty gears.

STRONGER:
OEM gear sets are machined from 8620 forged steel. The GLM gear set is machined from a higher alloy forged steel. The stronger teeth and higher alloy steel results in a gear that is 50% stronger than any other comparable gear set. These durable gears are capable of operating with up to 300 horsepower.

MORE DURABLE:
The new GLM gear set has fewer, larger, and stronger teeth. The pinion gear has 12 teeth and the forward and reverse gears have 22 teeth. The original OEM gear set has 14 teeth on the pinion and 26 teeth on the forward and reverse gears.

QUIETER:
During the gear machining process, an additional pass is made over each tooth for a finer surface. This makes the gear operation especially quiet.

IMPORTANT NOTE:
The new heavy-duty GLM 700-22666 gears will not interchange with the standard gears. For individual gear replacement, you must use the standard duty GLM 700-22623 pinion and forward gears or the GLM 700-22624 reverse gear.
