Mercury Impeller Differences between Lower Units

[dry3]

What is the difference in water pump impellers and housings in 2.4 V6 application such as a standard lower unit VS 4 hole CLE in 90-93 years.

When replacing an impeller for a switched out lower unit what do you ask for?

Are all 2.4 lower unit housings using the same impeller?

Thanks for any information!

The impellers are the same, Merc. #47-89984,this is used in the 2.5 gearcases also. The upper housing's are the same, but there are 2 diff. lower housing's. Get the lower housing for what the gear case is.
