OMC - COBRALOWER GEAR HOUSING GEARS
HEAVY DUTYGear Set GLM #22666Includes #21651 thrust washer**
NEW!
When all three gears need replacing in your OMC Cobra Sterndrive the installation of the GLM #22666 heavy-duty gear set is highly recommended. The heavy-duty gears can be used with all four-cylinder sterndrives* from 1990-1993 and all V6 and V8 OMC Cobra sterndrives from 1986-1993. It is recommended that a new clutch GLM #22625 (this clutch is not included with the gear set) be installed with the heavy-duty gears. The gears can be used with the standard 1-3/16" diameter prop shaft (1986-1990) or the heavy-duty 1-1/4 diameter prop shaft (19911993).
GLM #22666 heavy-duty gears fit these OMC Cobra Sterndrive units: 3.0L/181CI 4.3L/262CI 5.0L/302CI 5.0L/305CI 5.7L/350CI 5.8L/351CI 4-Cyl. Chev. V6 V8 V8 V8 V8 Chev. Ford Chev. Chev. Ford 1990-93 1986-93 1986-93 1986-93 1986-93 1986-93
STRONGEROEM 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 DURABLEThe 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.
IMPORTANT NOTE:The new heavy-duty GLM #22666 gears will not interchange with the standard Cobra gears. For individual Cobra gear replacement, you must use the standard duty GLM #22623 pinion and forward gears or the GLM #22624 reverse gear.
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.
*Except 1990 2.3L **For model year 1991 OMC increased the prop shaft diameter at the carrier needle bearing (not the prop splines) from 1-3/16 to 1-1/4 inches. Some older gearcases may be fitted with the new large diameter prop shaft. The large diameter prop shaft utilizes a thrust washer (included with this gear set) between the prop shaft and reverse gear. Discard the thrust washer when using the small diameter prop shaft.

For the 1991 model year the OMC Cobra lower gear housing was redesigned with a stronger propellor shaft and bearing carrier. Propellor Shaft ChangesA shoulder machined into the propellor shaft contacts the reverse gear and prevents the shaft from being pulled out of the gear housing when shifted into reverse. The 1991-1993 propellor shaft utilizes a hardened steel thrust washer between the shoulder and the reverse gear. This hardened thrust washer keeps the shoulder on the prop shaft from damaging the inside of the gear when the boat is shifted into reverse. The shoulder on the 1991-1993 propellor shaft is machined deeper to accomodate the hardened thrust washer. Another improvement on the 1991-1993 propellor shaft is an increase in diameter from 1-3/16 inches to 1-1/4 inches. The diameter was increased at the needle bearing, the prop shaft seal and the propellor thrust washer locations. The propellor splines remained the same.
Bearing CarrierThe 1991 - 1993 bearing carrier was redesigned with two hold-down tabs and two 5/16 inch bolts holding the carrier to the gear housing. The older carrier installs with four 1/4 inch bolts, a retainer plate and two internal retainer rings. The new carrier GLM #11408 also comes with a larger needle bearing and prop shaft seals for the larger diameter prop shaft. It can only be installed into 1991 and newer lower gear housings that have the notches for the hold down tabs.

*The GLM #28830 complete lower gear housing is a direct replacement for the 1981-1985 OMC lower gear housing. The installation of the 1981-1985 ESA (Electronic Shift Assist) components and shift cable are necessary to replace the lower gear housing on the 1978-1980 OMC sterndrives with hydraulic shift. #The GLM #28830 complete V6/V8 lower gear housing (large diameter) can be used to replace the 1978-1985 four-cylinder lower gear housing (small diameter) if the upper housing gear ratio is changed to 21:20. The installation of the 1981-1985 ESA (Electronic Shift Assist) components and shift cable are necessary to replace the lower gear housing on the 1978-1980 OMC sterndrives with hydraulic shift. ^The GLM #28600 lower housing will not replace the 1978-1980 OMC lower housings with hydraulic shift.

OMC - STRINGERUPPER GEAR SETS - 1973-1985
GLM is first in the marine industry to have all of the OMC 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*. All 1973-1985 OMC upper gear housings are identical** except for the tooth count on the gears. Below is a chart showing the tooth count for the different size engines used with OMC sterndrives.All GLM upper gear sets come with: GLM No. 21544 21545 21547 OEM No. 382212 379585 375761 Item Bearing Bearing Bearing

*All lower gear housing ratios are either 2.0:1 for the four-cylinder engines or 1.83:1 for the six and eight-cylinder engines. **The original driven gears in 1973 and 1974 upper gear housings are not machined for a centering cone. All 1975 and newer driven gears and all GLM replacement driven gears are machined for a centering cone. A new drive shaft with shorter splines and a centering cone must be installed when replacing the original (non-centering cone) driven gear.
Rebuild your OMC powered boat with high quality GLM parts! GLM is the source for OMC parts!

Upper gear housings, model year 1973 and 1974, with the original driven gear (no centering cone) require GLM #22423 drive shaft with longer splines. This drive shaft fits only the high profile gear case. GLM does not manufacture the drive shaft with longer splines for the low profile gear case. All 1975 and newer upper gear housings and all older upper gear housings utilizing the new driven gear (with centering cone) will utilize drive shaft GLM #22412 (low profile) or GLM #22422 (high profile). **The high profile upper gear housing was discontinued for 1978. ***All 1978-1985 upper gear housings are low profile.

Strongest Lower Gear Housing Assembly in the Marine Industry for 1978-1985* OMC V6 and V8 SterndrivesWithout Shift Assembly
All GLM replacement lower gear housings for the V6 and V8 OMC Stringer sterndrives have the new heavy duty #22666 gear sets. This new gear set has fewer, larger, 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. During the gear machining process an additional pass is made over each tooth for a finer surface. This makes the gear operation especially quiet. These durable gears are capable of operating with up to 300 horsepower. All GLM lower gear housings have the large 1-1/4 inch diameter prop shafts with a reverse thrust washer installed between the shaft and reverse gear**.*Many 1978-1980 OMC sterndrives have had the hydraulic shift lower gear housing replaced with the 1981-85 mechanical shift lower gear housing. Sterndrives with the original hydraulic shift lower gear housing do not have an ESA (electronic shift assist) box or overstroke switches on the shift converter. 1978-1980 sterndrives that have been converted to the mechanical shift lower gear housing do/must have the ESA and overstroke switches installed. **For model year 1991 OMC increased the prop shaft diameter at the carrier needle bearing (not the prop splines) from 1-3/16 to 1-1/4 inches. The larger prop shaft/needle bearing is a direct replacement into the 1981-1985 lower gear housing and is installed in all GLM lower gear housings.

OMC - STRINGERLOWER GEAR HOUSING GEARS - V6 & V8
HEAVY DUTYGear Set GLM #22666Includes #21651 thrust washer*
NEW!
When all three gears need replacing in your OMC sterndrive the installation of the GLM #22666 heavy-duty gear set is highly recommended. The heavy-duty gears can be used with all V6 and V8 OMC sterndrives from 1978-1985 with mechanical shift (not 1978-1980 with hydraulic shift). It is recommended that a new clutch GLM # 22625 (this clutch is not included with the gear set) be installed with the heavy-duty gears.
GLM #22666 heavy-duty gears fit these OMC Sterndrive units:
STRONGEROEM 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.

1981-85 1985 1981-85 1981-85
MORE DURABLEThe 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.
IMPORTANT NOTE:The new heavy-duty GLM #22666 gears will not interchange with the standard gears. For individual gear replacement, you must use the standard duty GLM #22623 pinion and forward gears or the GLM #22624 reverse gear.
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.
*For model year 1990 OMC increased the prop shaft diameter at the carrier needle bearing (not the prop splines) from 1-3/16 to 1-1/4 inches. Some older gearcases may be fitted with the new large diameter prop shaft. The large diameter prop shaft utilizes a thrust washer (included with this gear set) between the prop shaft and reverse gear. Discard the thrust washer when using the small diameter prop shaft.

It is recommended that the above standard duty replacement gears be used only with V6 powered sterndrives listed below: 3.8L/229CI 4.3L/262CI V6 V6 Chev. Chev. 1981-85 1985GLM recommends the heavy-duty gearset #22666 for all V8 powered sterndrives.

* Heavy Duty Gear SetIn 1976 the first V6 Johnson and Evinrude outboards were introduced. The V6 outboard had a new design, large diameter, lower gear housing with hydraulic shift assist. For the 1978 model year the OMC stringer sterndrive was redesigned, the old electric shift lower gear housing was replaced with this new hydraulic shift assist, large diameter, V6 outboard gear housing. The hydraulic shift assist lower gear housing did not prove to be reliable and was replaced with a mechanical shift lower gear housing on the 1979 and newer V6 outboards and the 1981 and newer OMC sterndrives. OMC made available to owners of 1978-1980 sterndrives a mechanical shift lower gear housing conversion kit for a very low price. This kit consisted of a complete lower gear housing, an ESA (electronic shift assist) box, ESA activation switch and two shift overstroke switches. It is the customers responsibility to determine if a 1978-1980 OMC sterndrive has the original hydraulic shift assist lower gear housing or has been converted to the mechanical shift lower gear housing.
