Hello!
1988 Mercury 90hp EPLTO. s/n 0b312461
I want to put a new impeller into this motor. I haven't done this before, but I am fairly certain that I can do this job myself. I have read a bit and watched a few videos on Youtube of guys showing you how to do this.
I just want to be sure I have it right:
Remove Lower Unit
Remove cover, take out old impeller, and remove gasket(s) from on top of lower unit (the new ones come with an impeller "kit"?)
Put new gasket(s) in and put impeller into housing using dish wash liquid for lube. Slide cover and impeller back on shaft lining up the notch/key. Tighten bolts fairly tight but not super tight.
Reinstall Lower unit and test on muffs.
Is this correct?
Is there anything I need to be careful to do/not do during this? Also any tricks/tips?
As for the shift connections, as long as I don't move the shift rod on the lower unit or at the remote, it will all line up when I reassemble OK?
As for testing, if water comes out the pee hole as per old impeller then I can be fairly certain everything is OK?
As testing in Forward and reverse with muffs will make certain gears are all OK?
What direction does the shaft turn (when looking DOWN shaft towards lower unit)? Do I need to make sure impeller "wings" are facing correct way when it spins?
Sorry for all the questions, I just like to be sure of what I'm doing!
