I toasted my impellor and my housing has lots of scratches. I installed a new impellor but cannot get the pump to flow enough water.

I'm looking to replace my pump with the Hardin SS pump. Called them but the Hardin SS pumps are backorder three weeks minimum. :faint2::faint2:

Hate to not be boating for another three plus weeks!!! Anyone know where I can get Hardin SS pump?

I did find one Hardin SS pump for my port motor. It's now installed and works great. I have noticed after running the boat hard the temp spike is only a few degrees and quickly returns to 160. With the OEM pumps i was getting a larger and longer temp spike!

Now I just need to find one for the other motor!!

Interesting...I noticed the same spike after running hard...I have 2 Hardin units that I will install sometime....soon.

Now, if there is evidence that this is a temp fix I will have to keep an eye on it. I'm just glad for the first time in many boating seasons I am starting out with good pressure on both motors.

Question for the Hardin Marine folks. Does that stainless steel replacement pump incorporate the quick drain valves of the factory unit? From the picture I don't see the dump valve?

Our pump kit has an impeller fitted to match the s.s. plate. The pump goes back into the bracket without grinding and pulley relocation. Check amarket.com/im496reb.htm

My OEM pump had scoring in the main housing and the back plate. And the shim kits cover both sides.

Am I missing something?

You need to google im496reb

I've bought a couple of the Aftermarket Marine rebuild kits (bearings, seals, shaft, etc) and had problems with the machined tolerance of the shafts. Everything fits and goes together nicely, but the press on the pully is too light. To resolve the problem I used an old shaft on one pump and welded the pulley onto the other (it is now disposable). Have you remedied this problem?
