Great! will do, thanks for the tip on the "pop riveted" serial number, will make things A LOT easier if I have that! I am running a 95 454EFI with a Bravo 1 drive, which holes are the low water pickups?, I just put the muffs over the "gills" on the side of the outdrive, are there other areas that need a water supply? this would be much easier if I had room to install a sea strainer!
I have flushed water "backwards" through the suction side of the hose, but, how hard is it to actually remove both the sea water hoses? [at the outdrive and wherever the pressure side connects] I like the idea of checking to see if there is any small rubber pieces stuck in there, I really dont want to have to tear all this stuff out again in a week or 2 to get the rubber pieces out.
THANKS!!!

I would call Dana at Doller Marine. She can listen for a few minutes of "thingy majigs" and the "blue part next to the black part" and after a few days the right part will come in the mail.

OK, I picked up a rebuild kit today, came with a new plastic housing, hardware, wear plate and a small O ring
Seems easy enough, but, I was wondering where does the small O ring go?, there is already one pressed into the plastic housing, and there is no reciever groove in the wear plate, so, where does the small O ring go?, I assume is seals the shaft up somehow, but, not sure how.
Also, do I have to use sealant on the threads and/or housing or wear plate when I reassemble the unit?, Thanks for all the help guys, I was a little hesitant to try this, but, after getting some good input from OSO members I am not quite so intimidated now, Thanks Guys!

According to the diagram I looked at it goes on the shaft first,then the wear plate,then the impeller and finally the body.No sealant is needed but you may want to put something like vaseline or white grease in the pump body to lube the impeller on start up.Does that o-ring actually have square sides on it? It's known as a quad ring.

Two things....
1. Make certain it is an actual Mercury part and NOT Sierra branded. Had troubles with Sierra's in the past.
2. Do NOT, use vaseline, white grease or any type of grease for that matter. The little globules of grease dont dissolve and can find their way to some small orifice and clog it up. Use dishwashing liquid; dissolves in water completely.
