On my 70 hp, all I have to do is pull a cotter pin and unscrew the king nut. Once it's off I just pull the impeller straight off. It's a piece of cake!

You have to remove the lower unit. The Impeller is located on the drive shaft and rotates clockwise. When you put on a new one as you push the case down over the impeller turn the drive shaft clockwise so it slide in easy. It good to use a little grease on the rubber ends to help it slide. Below is a link and it show all the parts. The case is the large black up left and has bolts holding in down. If, you going to do this, I would buy a kit with everything as some may be worn, including the plate under the impeller.
Now, to drop the lower unit, I not sure I can explain. I would remove the prop first, just so it out of the way. Shift to reverse and you may need to remove a retaining screw up in the engine that hold the shift rod. Remove the trim tab above the prop and look/mark how it positioned. remove the bolts holding the lower unit and it should be ready to drop. May need to tap on it with a rubber mallet, do not use a metal hammer, though it may work it can crack something. I put it in a vise with towels to pad and then do your thing. Good Luck.
I just hope this all correct, it been a long time I done this.

Your first two answers told how to remove the propeller, not the impeller.
I just changed the impeller (water pump) on my Mariner and the third answer is going to be the one you use.
Remove the lower unit, it is hidden in there and driven by the shaft that runs to the prop unit.
I strongly suggest you try and find a manual for it, I didnt and wish I had. It is not horribly difficult but some technical advice never hurts.
Good Luck.

Once you remove all the bolts you can find, try to pull the lower unit straight down. If it doesn't come down with little force you need to get some supervision. Forcing it & breaking anything will cost you more to repair than having a mechanic install the pump to start with.
Checkout Iboats.com boating forums.
Good luck.

remove the cotter pin on the jet-nosed plastic cover and the shear pin will be on the inside, remove that pin and then the propeller and install the new propeller and a new shear pin.

ther may be a spinner cap that un screws and it may be left hand threads then you should see there is a cotter pin to remove
then a nut and maybe a washer
the prop may be tapped off with a rubber hammer
if it is really rusty you may need a puller
good luck
