Backflushing a 525efi
 

Just got done changing out the impeller and housing tonight on one of my 525efis' and can't figure out how to backflush this motor. I was only able to locate about half of the old impeller when I took the pump apart, so the rest is stuck somewhere and I want to get all of it. What hose and where is it located?

http://www.mercruiserparts.com/Show_...28Sea+Water%29 look at part #8,,,disconnect it from the heat exchanger at #2,,,install garden hose into #8,,,

Thanks for the help twin, got it done and glad I did it because there was quite a few pieces stuck in there.
