Not to steal your post, but since you have been through this I am fixing to go into the same thing, but in reverse. I have a RDSL-26R (’64-40hp) that I am going to put a RXE-13 (’65 33hp) gearcase on. I will be changing the driveshaft from the long engine into the short shaft. I plan to just cut the woodruff key to drive the wider impeller. I think that is the way to go. The 40hp has the dual bypass water pump. Is all of that done in the water pump? The gearcase hsg. shows the different part numbers Johnny_inFL mentions. Does anyone know what the differences are that cause this part number change? The internal parts are the same as far as I can tell. Just wondering what I am getting into. The A/V plate is all broken off the 40hp from a whale tail application.
