2008 50 HP Mercury Water pump

[armymp42]

The waterpump is weak on my 2008 50 HP Mercury. I am wanting to replace it myself but can not find any instruction online. Can someone help me out with this. I have also looked everywhere online for a maintenance manual for my 2008 50 HP Mercury 4 stroke. I can not find one. If anyone can tell me where to find one it would be great. You can contact me at armymp42@yahoo.com Thanks
