I recently replaced the water pump on my 28HP Johnson. I used a kit...
I brought it to a shop to have it pressure tested and it passed fine.
When I did the work, I had (2) o-rings left over and I asked the guy at the shop about them. He said they should go on the top of the housing (down the shaft). There should be a "cone" or "tube" that also goes on the top of the housing, around the shaft that keeps water from going up the shaft.
The problem is... I dont have that "tube" on my motor. Did it ever exist? Or did the last guy lose it?
Do I NEED this tube and o-rings? If so, does anyone have a part number for it?
I'm thinking I do need it, because when I shut the motor off, I get several ounces of "crud" from the weep holes. See the other post I made: http://forums.iboats.com/showthread.php?t=574045. Is this all related? I'm wondering if the crud is water mixed with other stuff... just weeping out. Would the "tube" stop this?
My last question... Does that tube keep water from coming "IN" the water pump? Or does it keep water from going "OUT" of the water pump.
I attached some pictures of what I "think" the part I need is. Also, the top of my housing and the O-Rings.
Thanks,
