Yes I removed the powerhead and poured water thru, I pulled a small chunk of silicone out of the powerhead and suspect that, just wanted to be sure I wasnt shov-lin it against the tide with the 5/8 ID tube. Im also going to remove the cone nut and check the pump.. then re-try Thanks.
make sure the water pump is in correctly. if you're using it there is a certain way the pump has to be in the unit. if you look at the pump housing as it would be installed in the foot there is a 'bump' by one of the holes in the housing. that hole shoud be by the exit hole by the tube going to the block.

I took the cone etc. off and the pump looks OK. Ill run it again when I get a chance to set up the custom-made [from junk] motor jockey with barrel-o-water attachment and lawn mower throttle cable. Thanks for all of your input, Mike
I just tried to run it again and still no water, next Ill have to take the lower unit out and see whats what. I made a copper tube [same size as stock], copied the end cut and length that goes from mid to foot and siliconed it into the foot adapter. Its the last thing I can think of.
I also drill and tap the sides of the foot adaptor to install a 1/4 hose fitting that taps into the hole in the foot adaptor for the water. Then, run another water inlet hose to the powerhead. The other side I just put in a 1/4 pipe plug. This also allows to make make a flush fitting that would thread into the tapped hole (that has the pipe plug), so that you could run your engine on the garden hose.

I like the idea of tapping into the sides of the adapter, got all weekend to think about it since Ill be away at a wedding.
Just some food for thought.
I've worked on more than a couple OMC service motors that would not pump water. I looked and looked for a water pump problem. Came to find out the powerhead had a blown head gasket that was pressurizing the water jacket, making it impossible for the good water pump system to overcome. I replaced the head gasket and SHAZAM! pumped water again!

Ive got one more question just in case.. Ive noticed that on my 1 to 1, older short skeg - multi inlet hole foot theres a bushing on the top mount surface where the cooling tube goes in about 1/8 to 1/4 and stops. On another 20H tower I have around the tube sticks out of the bottom about 2 in and has a slanted cut facing back towards the waterpump housing. Which of these types should be used for a long skeg single hole foot or are they interchangable? Thanks, Mike
