Water Pump, G55-2, 1989 Barfoot Nautique

If you're not going to rebuild the old pump please send it my way, I'll take the risk.

Only took me 34 minutes, I'm getting geekier

I'd say the Jamestown Dist catalog "ain't quite right" in their description. It's pretty obvious that the same impeller doesn't fit all the listed pumps in their description. It fits most of them but it would be real sloppy in a G55-2.

Ken,
I was going by what Jamestown had in their description which does include the G55-2.:
"It is designed to fit Sherwood pump models G15, G21, G30-2B, G30-2, G9901, G9903, G55-2, J70, and K75B."
Regarding the impeller, I'd sure call Jamestown before ordering!

Pete
It's obvious he wants this thing running for the 4th of July weekend and he ordered a complete pump to accomplish this.

He found somebody on the Supra forum who solved his problems with a new pump, so he's doing the same.

The seal didn't leak when he was supplying it with a garden hose.

It's his money and his decision to get the new pump

Sherwood major rebuild kit

You're the one with your eyes and hands and ears on it and when you figure you've covered all the bases you do what you did........buy a new pump. It seems like you covered everything so there was only that one option left.

Hope it works out.

The pump should turn relatively hard by hand but trying to describe how hard is hard to do.

My pump like that puts out about 4 to 5 gpm at idle with about 1 or 2 pounds of discharge pressure.

Don't forget to update this thread with the results

Lots of good input guys! I was able to find someone with the same problem on an old Supra forum thread. I just ordered the new pump, and spent the extra $40 to have it here by Friday.

So from what I gather, with the impeller in, it should be really tough to turn by hand? because mine was pretty easy, and I wasn't able to feel much suction on it.

So this is the old pump from the froze up engine? I suppose the PO could have ruined the pump along with the engine if nothing was drained since the pump would remain full of water when it began to freeze up. If that were the only thing preventing me from hitting the water I'd just buy the new pump and rebuild this one completely next winter. It's gonna be July in a few days...

Comes in at 6 [from below] and leaves at 9 [towards below]. It kinda makes sense...

Ken, but he posted this. Which pump does he have?

edit   OOPS, I think I see what you are saying now. I thought that would be at 6:00 and 6:00

That is why I wear a digital watch

HW, Great illustration.    The RR 351 is what I was talking about. Wish he would post some pics of his setup. Mine is a cheap plastic unit (only cheap in quality, not price). I should probably replace with bronze unit, but it works for now.

Did you have the cam out of the housing when you rebuilt it? The cam should be at 6:00 if inlet is at 3:00 and outlet at 9:00. Assuming the pulley turns CCW standing in front looking rearward. You are positive the impeller is in fact turning??
On my test stand, I just stick a garden hose in the trans cooler and it works great. Temps are perfect and I know that it has to be sucking air with the water cause the hose won't overflow when it is running but will when shut off. Granted my setup is far from perfect but it illustrates just how much suction you should have. Something is backwards on your setup.

Yep, my bad.

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?

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