Great pressure, great replacement pump
by James from Griffin, Georgia on May 23, 2017
This kit has everything needed to rebuild the water pump. My older Merc has as much flow and pressure as it ever has. Keep in mind, just looking at the impeller doesn't always tell the story. Mine didn't look that different but the old one had permanent deformation in the impelar blades that I assume make it not as efficient.

Perfect
by Matthew from North Augusta, South Carolina on September 23, 2016
This was just what I needed. When I took my old base off I noticed that the seals in my old pump were split. Fortunately, I installed this unit before I filled my lower unit with water. The pump fit perfectly and the water output / pressure is good again. No more overheating while pulling the kids on the tube. I would recommend this kit over just doing the impeller kit. You might as well do the whole job instead of just half of the job while you have the lower unit off! Besides, you can't beat the price.

Water pump kit complete
by George from Westlake, Oregon on September 03, 2014
I received my water pump kit and was totally pleased. The quality is wonderful. I only have a problem with my shipping. I ordered it overnight air and did not receive it when I should have. The driver that delivered it told me that the plane made an error and delivered it to the wrong airport. I had a mechanic ready to work and had to pay him for doing nothing but stand around for an extra hour (thankful that's all he charged me extra). I called UPS and they flat out lied and said it was weather trouble besides, I would have to contact I-boats as they are the ones that paid and shipped it not me!!! This may be true but the money came out of my pocket not I-boats. Anyway that is my complaint. The product is fantastic, UPS stinks. GRM

Water pump kit
by John from Plains, Georgia on June 17, 2013
The only thing to make the product better and get 5 stars would be to include instructions. Either through a direst youtube link or website link. As it was, I had to search for instructions for proper installation. One video showed it installed incorrectly.
