What's This??? - 727 ?? vs CCC Gearcase
Here's two pictures that show the differences of two OMC gearcases. An original CCC gearcase is on the right and has an original length stubshaft installed and a longer one beside. Needed the longer stubshaft to use this GC with a 235hp block that has a stock crank - not the damper crank.
It turns out that the GC on the left has a 14-3/8" driveshaft - the same length as my CCC GC with the longer stub-shaft. The original CCC driveshaft length is 13-1/8". (Measured from top of gearcase housing to top of driveshaft)
**** Waterpump base on left is P/N 727D1110 Waterpump base on right (CCC) is P/N 322358 ****
Lots of things are different
- long vs short hub prop shaft
- slightly larger / different water pump
- Fill / drain holes located higher
- Casting is generally heftier - cavitation plate thicker
- No P/N cast into the Left gearcase housing
- shorter skeg
- 10 studs vs 8 studs for mounting
- Haven't checked gear ratio yet - 15:17?
- Bulge in case just below cavitation plate. Reinforced stud area to right of fill holes
- profile different between cav. plate and prop-shaft
