Should be on the transom, right between the rails of the swim ladder, when it's down. Will shoot you right in the face if you're slowly lowering yourself into the water:)

On my 2001 MKII mine exits on the starboard side of the transom. I added a backup bilge and placed a through hull on the port side. To check for a blockage I would run something back up through the through hull.

Its not uncommon for certain bilge pumps to fail to prime, so it will whirr away but not move any water down the hose. This is most common if you have too large of a bilge pump in too small of a space in the keel sump, and/or and old worn pump where the impeller is toast.

Agreed. And I'd add that it's easy for the water inlets on the bottom plate to get clogged with slime and whatever nastiness gets into the bilge. You might want to remove the pump from the base and check it out.

Rick,

Not sure if I understand the true issue you are having, are your bilges full and you can not get any water out? If this is the case the previous posts have good suggestions. You can see water being discharged out at the transom when the pump is on if it is moving water.

If the bilge has some water in it but not full this may be normal, it is on my boat and I always use a sponge to remove the last of the water. If this is the case it is just due to the fact that the pump in the bilge pushes the water from the pump to the outlet at the transom uphill about 15 feet. After the pump shuts off gravity will cause the water in the line between the pump and the transom to run back into the bilge. A 1/2 line 15 feet long will hold about a quart of water that will flow back to the bilge.

Some have suggested a check valve at the pump to keep the water from coming back into the bilge. The problem with that is that if the valve sticks the pump will not work and you have a larger problem than just a bit of water sitting in the bottom of your bilge. If you have a check valve in the outlet line of your pump this could be your issue. If it is just this return water from the line and you just can not live with it I guess you could install a second pump wired in paralel with the main pump that would come on any time the main pump comes on and empty the line between the bilge pump and this second pump, for me the sponge works.

This may not be your issue, I was uncertain from your post but, seeing that you are fairly new to your boat I just wanted to make sure you were aware of this little trait.

Rick,
One thing you might want to do is to run a fresh water hose in the bilge, and let the bilge pump do its thing for a while, cycling on and off. I do that every season to clean things out. Let the hose run into both the forward-most and aft-most compartments. The water will flow thru the limber holes to the compartment with the bilge pump. When you see that the water exiting the transom is clear, the bilge should be much cleaner. Just a thought.
