Two things:
You have to disconnect the two parts of the shift rod from each other after lowering the gearcase a little.

There is a pin through the drive shaft near the top that supports the bits and pieces that make up the seal at the top. You have to turn the engine (plugs out) until that pin lines up with a slot at the top of the exhaust housing. Then the shaft can be pulled away from the crankshaft​

Once the gear case is off you will be able to remove the water pump housing to reveal the impeller. Inspect the housing to determine if you need a complete overhaul kit or just the impeller.

Now is a good time to change the oil seal below the water pump if there is any possibility that it is leaking
