Hi!
I've bought a Mercury 4.5 this weekend and after getting it up and running I noticed that there isn't any water coming out of the peehole.
The first thing I did was to change the water pump and as expected it wasn't pretty... some pieces of the water pump came out when I removed the lower unit and the pump house.
With the new water pump installed and everything put back together and still no water comes out of the peehole.
I took apart the water pump again and found that there was a bit of rubber from the old pump blocking the intake, I took my blowgun and blew in the hose to the peehole, it came air from the feedingtube and I though that it would work now that I've cleaned out the intake.
Nope, still no water from the peehole, from what I can tell there's not blockage in the feedingtube and I can't figure out what to do.
I also hooked up the lower unit to a power drill and the the water pump seems to be working, it's not that much of pressure but I don't know how much RPM I get from the power drill either.
I tried connecting a hand pump to the hose to the peehole and pump water backwards through the system and it seems to be working as it should. I haven't tried from the feedingtube as I don't want to push possible blockage further into the engine.

I'm all out of ideas and really need help to solve this problem.
Thanks in advance for any advice that could help me.
