Johnson 3.3

[GeoffH2o]

I have a very reliable and very basic Johnson 3.3 and don't seem to be able to get a stream from the water pump. The impeller seems OK and I've stuck a paper clip in the end tube. Does anybody have any ideas how to flush through the system? Geoff

I have on a old suzuki that had the same problem. I dropped the lower unit and attached with various tubing/reducers a jury rig that allowed me to connect a garden hose directly to the coolant tube that normally connects to the water pump. To be honest, I don't know if this is good practice, but it worked in my case. If you go through the trouble, might as well replace the impeller while the lower unit is off.

Replace the whole waterpump including the impeller. It is an easy replacement and most any DIYer can handle it.
