"Ok, I'm trying to replace

"Ok, I'm trying to replace the water pump impeller on my Leg, its aa 175hp model with Ford 302 engine. I've seperated the lower unit, what I think is the exhaust housing is off the upper, now I took out the 4 bolts holding on the impeller housing, but it wont slide off?? I guess the impeller drive shaft has to come off with it, it says in the manual to use a 1/4 punch and go through the top hold and drift it out?? I've tried but wont budge?? Do I have to disassemble the whole upper unit to just do this dang water pump????

Thanks allot

Will"
 
"Ok, I got it out, I went back

"Ok, I got it out, I went back out, and just tapped on the outside of the housing and it came. I picked up an impeller, but looks like it needs the housing too, its fairly pitted, so would be wise to do it as well. Also I want to make sure I orientate the housing correctly when going back together?? I never really noticed when it came apart how it goes, what should I look for? My local place is expensive, so maybe try to get one off ebay."
 
"Ok, now I see the bolt holes

"Ok, now I see the bolt holes are not symmetrical, so it will only go on one way. I've ordered a complete pump kit, should be here soon."
