Re: Impeller – key vs pin to shaft

[John]

well to start off with, I know absolutely NOTHING about the innards of an outboard !!!
in the past, I have always taken my motors to someone else for maintenance and repairs.
With the encouragement of a renowned member here, "Pappy", and others, of course,
I have gathered up the confidence to dive into a motor (with the proper manuals) and I still
have problems, but are quickly addressed in this forum by the VERY helpful professionals that have "been there – done that".

I guess the line is forming to ask you . . . . WHY ??? is there a reason of not using a 40hp foot ?
They are very plentiful on e-bay ….. Plus, I just acquired a RDS-24L 1962 Johnson 40hp short shaft
that will probably be a parts motor. It looks kinda rough around the edges.

I have had both the 33 and 40 lower units side by side and they are nowhere close to being identical or interchangeable.
The WATER PUMP part number that I have for the RDXE 33hp is 303831
and the WATER PUMP p/n for the RDSL-22 is 312612
and the mounting screws are nowhere close.

and again, I have NO IDEA if what I have is original to the motors or have been changed out over time.

and no, you are not jacking the thread – it is sharing good pertinent information.
