What does OMC Shift Assist Module do?
The electronic shift assist reduces shifting effort by limiting engine RPM. This also results in smoother shifting. When the vertical drive is all the way in forward or reverse gear the overstroke switch shuts off the electronic shift assist.
Can you bypass shift interrupter switch?
You don’t need to take the control apart……just follow the yellow wires (with red tracers) and you will find a connection. You can disconnect it there and jump the two wires together to bypass the switch…but don’t tell anyone I told you!

Where is the water pump on an OMC Cobra?
Volvo-style gears are renouned for near-indestructibility. Note the water-pump located on the back of the F-N-R gearcase on the 1993-on OMC “King Cobra.” I’ve been told that the Volvo SX and DP drives use a similar waterpump attached to the engine crank pulley (inside the boat).

Why did OMC change the bite angle on the Cobra?
Thanks to Carl G. Craver for this tidbit. Some early Cobras ate their gearsets. OMC initially thought the clutch dogs were disengaging due to insufficient “bite” (interference cut) on the clutch dog teeth. OMC increased the bite angle from two to five degrees, and all subsequent Cobra clutch dogs have five-degree teeth.
