GLM is proud to introduce our Upper Gear Sets for OMC Stringer!
All GLM upper gear sets come with:
GLM #21544 (OEM #382212) Bearing
GLM #21545 (OEM #379585) Bearing
GLM #21547 (OEM #375761) Bearing
GLM is the first in the industry
to have all of the OMC Stringer upper housing gear ratios!
Different size engines require different gear ratios in the
drive. The manufacturer changes
these ratios with different
gear sets. The gear ratio change is in the upper gear housing*.
Below is a chart showing
the tooth count for the different size engines used with OMC
Stringer
sterndrives.
