have a mercury 50, 3 cyl, model 87 and need to replace the water pump. I have bought 2 manuals and can't find good step by step instructions on this - any help?

I don't have any instructions other than the service manual. Start by putting in reverse gear, remove all bolts holding lower unit and remove lower unit, remove water pump housing, apply grease to new water pump impeller and inside cup on water pump housing, turn drive shaft in a clockwise rotation as you are pushing housing down over water pump impeller, use anti seize or grease on all bolts before assembling, apply grease to splines on drive shaft and shift shaft, as installing lower unit align water pump tube to water pump and align shift shaft, rotate prop to align splines on drive shaft and tighten lower unit bolts. Check shift and water pump operation after reassembled.
