Water Pump, G55-2, 1989 Barfoot Nautique

Hi guys! I'm homing to get some help here:
I bought a very well taken care of BFN 2 months ago now, and put a new motor in it due to the previous owner not winterizing.

I have the boat running perfectly, but now I cannot make enough water pressure out of the water pump (impeller housing) to make it too the thermostat housing. The bearing on the pump seems fine, and this is impeller has all of its fins. The pump is a Sherwood g55-2 on the 454 motor. Hoses are installed correctly, and it's like the water can't over come the 16" climb to the thermostat.

Any ideas of what the issue could be? I don't have any leaks between the water inlet, and the inlet side of the pump. Also, the screen and Velvet Drive Oil cooler is clear.

Yup, sounds like the pump is plumbed backwards. Hope you just swapped the hoses vs got a LH engine back- that would be a much bigger can of worms.

You don't need to worry about the direction the impeller is installed- it will right itself.

HHHMMMMM, Very well taken care of yet wasn't winterized????? Isn't that an oxymoron.

Like others have stated, the pump is probably reversed and I hope that the replacement engine was the correct rotation.

Yes, I'd sure be looking at other "well taken care of" maintenance items!

I'm sure the CCfan family would be able to handle it.

^yes, the hoses "cross" underneath. The cleaner looking install means you reversed the hoses. The pump cannot be installed backwards.

There are only so many reasons the pump won't work. Crossed hoses, major air leak, worn out pump...

As for fins on the impeller, I have tried pre loading, Both ways. Even if you load the opposite way, the fins work back into the correct direction it spins.

A picture tells a thousand words and would correct any misunderstanding's

This is where I was at before I posted this thread:
When I bought the boat, I replaced the motor with a new RR motor. The motor runs great!
I also replaced the impeller with a Sierra brand knock off of the Sherwood 10615 impeller.
Once I found that I could not get water to the thermostat by sucking water out of my Fakelake, I just hooked a garden hose directly into the inlet hose (from the elbow in bottom of hull) and was able too water to thermostat and cool the whole motor down that way. Once I saw that I could get water all the way to the thermostat on a garden hose, but NOT from drawing out of my Fakelake, I pulled all of the hoses off to look for potential blockage.
I did find old impeller fins stuck in places, that must have worked their way back into the pump, but all of those are cleaned out now. So as of now, after double checking all my hoses, I am still not able to draw enough water out of my Fakelake, to make it all the way to the thermostat. With the thermostat hose off. It will burp water out of the end, once in a while, but its not a steady stream like it should be.

The impeller I have in there now is a little tore up, but has all of its fins.
I am thinking about replacing it, again. But like I said, I just put that impeller in.

The Sierra's are known to be a problem. On the Sherwood, there's a ridge on both sides forming an "O" ring type seal on the housing that the Sierra's don't have. Get a Sherwood.

Cams can be worn too and the seal could be sucking air, but HW is right get a genuine impeller you will see the difference in their construction. Get that in sand spinning the correct way and let us know.

Sounds to me like the fake- a- lake needs to be relocated to the bottom of a lake somewhere.

You said it worked with the garden hose hooked up...............now do Hollywood's bucket method and see if it works.

Bet it will work OK unless the impeller is really ragged.

Fake- a- lakes can provide a lousy seal, letting the pump suck air and not draw enough of a vacuum to suck any water assuming this is the toilet plunger looking contraption.

Agree x100. Ditch the fake a lake and the Sierra impeller.

The thing that makes me nervous is I've used Sierra impellers before, along with fake-a-lake on my last boat (1988 SN2001) and never had these kind of issues. If I replace the hose, do you guys have any recommendations on what kind to use?

Yep, my bad.
