I just installed a new impeller in my 20hp merc. i am a little uncertian that the water tube went properly into the pump housing. it had a copper tube that was a little off and it took many attempts to get the lower unit to set into place. how can i test to see if the tube is in the right place? this is a 1967 model mercury 200 20hp.

Re: Water Pump Impeller

Maybe you could put on some muffs, remove the spark plugs to lessen the compression and turn it by hand to see if any water comes out of the tell tale. You may be able to see if it is partially seated that way. I just did mine and without the guide, I had a heck of a time getting things lined up properly.

I hate when there are extra parts after a task is completed.

Hey, if there are extra parts, and it still works, you didn't need them anyway.....JK
