Mercury 9.9 not spitting water

I have a 96 mercury 9.9 and it has been sitting for 6 months or so, I went to run it in a bucket water and noticed no water coming out of the pee hole. I have never worked on a outboard but have read that it is fairly simple to replace the impeller. Does anyone have a write up on how to replace it? I searched online but couldn't find anything for a smaller outboard. Any help would be much appreciated.

hope it helps

I don't know much about a 9.9, but on my other motors, I always carry a piece of weed wacker string. The pee hole can get clogged and the weed wacker string will unjam the dirt or debris. May be worth a nshot before replacing the impeller.

Make sure you had it in DEEP enough water.At least or above the cavitation plate.

Thanks for the reply's the video helps a little, I have read somewhere the motor needs to be in reverse before you take the lower unit off but i'm not sure, I probably should get a service manual. I took the hose off inside the motor cover and checked it for any debris, I stuck a piece of wire in but it seemed clean and free. I tested the motor in a short bucket of water with the level just at the plate where the suction was under water, maybe it needs to be a little deeper i will try tomorrow and post an update.

Just don't run it too long to get it hot [-X

If you don't already have a set you might consider buying a set of muffs, not that expensive and saves a lot of time. Good Luck!

Sounds like it might need a pump impeller. You may just want to put one in. Its just good insurance to have a new one put in even if the old one is not completely shot.

Yes i'm just going to replace the impeller and put new seals on the lower unit anyway. I would get a set of muffs for it but it doesn't have the side suction it has it right under the cav plate and from what i've see I think you need to remove the prop to put the muffs on? THANKS AGAIN FOR THE INPUT

Mercury (actually quicksilver) makes a muff that you have to take the prop off and it attaches to the cativation plate and the water pickup. they cost about $25.

Or just put it in a barrel. My 15 hp will hang off the back of the box and I can slide a big garbage can under it and fill it with water.
