    Here is something you may not know, the 1956 and older models 18 &10 hp lower gear cases used a shorter drive shaft bushing than the 1957 18&10 hp cases and the 1958 and up 18hp cases. That gave more support for the driveshaft and spread out the load forces and gave longer wear life for the bushing.
