quote Johnny_inFL:
Yes, it is the RXEL-14D motor – removed the 5″ spacer to make it a RXE standard.
the shorter lower shift rod fits well, I did not really “alter” the gear case, just made minor adjustments.
I too am concerned about the looseness of the smaller pin in the larger key slot.
There is no way to tell about any parts being original to the motor. BUT – the gear case part number for the 33 is the
same for a 1960 RDS-22 40hp I am working on: 302520. But, the 33 parts book calls for 593514
and the 40 parts book calls for: 377483. So anything is possible.
When I search for part number 302520 it is not clear as to what it originally fit !!!!
I thought of getting a larger diameter pin or grinding down a woodruff key to accept the impeller slot.
I really hate modifying things that I have no control over nor an easy way to inspect later on down the road without disassembly.
I will take the shaft to my machine shop tomorrow and have a slot ground for the correct woodruff key and be done with it.
NObody likes being stranded on the water due to taking a shortcut on something mechanical.
Other than that, everything is falling into place quite nicely !!
Thanks Fleet – lots of great information there.

Sorry, you are losing me again…There is no 302520 part number. The 33 and 40hp gearcases are definitely NOT the same for these years. Where did you find the part number 302520?
