Put new water pump in and nothing

[sven]

I just did my water pump and when I started it: only a trickle of water through the tell-tail hose and only when i reved the engine. When i went back to idle the trickle went down to nothing and i quickly shut the motor off. This time since i'm on cider blocks too far from a gardern hose, i had to use a 35 gallon plastic bin. I could only get the two intake slits under water. I was wondering if this could be the problem: Since a hose has water pressure, it gets up into the engine. Does more of the lower unit have to be submerged in order to allow the impeller to suck up water (maybe air getting into impeller)? Anybody have any clue as to what is going on here before I rip it apart again?
Thanks

I would try to get more of the lower unit in the water before ripping it apart again. Or get a longer hose and set of muffs.

If it still doesn't work - are you sure you installed the impeller in the right direction? I think you twist it in counter-clockwise on right hand rotation motor....I can't remember exactly....I always look at the impeller I'm removing to make sure I twist the new one back in the right direction. If you do tear back into it I'd make sure the impeller install is correct.

One last thing to check before taking it apart - you need to make sure the pee hole isn't clogged up. I've used a piece of wire to run up through the tell-tell to dislodge sand & unknown deposits before on 2 different motors. One time in particular I had just gotten the new impeller installed and it behaved exactly the way you described. I switched the direction of the impeller and same thing. So I had to tear it down a 3rd time to correct the impeller and come to find out there was a hard sand or salt deposit stuck in the tell-tell.

Best of luck,

your probably just sucking air from the exposed water inlet holes, add more water

What kind of motor? Older Mercury's don't pee until they have warmed up, although the water still comes out the exhaust port.

That is a good point

Also the water pickup tube may not be lined up right. On my johnson there is a 2 foot copper tube that runs water up to the power head and mine was doing the same thing then I found out that I had missed the powerhead with the tube. Also, make sure the grommet at the top of the pickup tube doesn't get rolled as you put it in. I use dish soap to make it slide in easier.
