NEW & REBUILT GEARCASES

  NOTE!! You MUST PROVIDE THE MODEL and YEAR when ordering. I cannot send you the correct parts otherwise!
Also, please be sure what you have: OMC Stern Drives (Stringer Models) are tilted by an external gear (mechanical tilt); OMC Cobra Models are hydraulically tilted and have the water pump in the upper gear housing; Cobra SX models are likewise tilted but are manufactured starting with the 1994 model year and have a belt-driven seawater pump on the motor. COBRA SX drives are NOT AVAILABLE from our rebuilder at this time.

Rebuilt and new gearcases are subject to availability.
