This might be an easy one for you guys. I decided to install a new water pump impeller on my CC. I took the lower unit off and broke it down but upon inspection I noticed that the water pump housing was a little burnt up so I decided to replace it. I also couldn't get the spacer off without breaking it. The problem is it was two weeks ago while waiting on the parts and I forgot how it all went together. Do the three washer go on then spacer then slip lock outside the housing or inside the housing? And do I drive the metal slip on the spacer or keep it right above it if it goes on after the housing? I bought it from someone who took it to barber marine so maybe rodbolt might have a suggestion.
