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.

Will this part Part # 18-3319 fit my 1986 Mercury XR2 150 outboard?
It depends on your engine's serial number. It should work, but the best way to be sure is to locate your serial number and match it up.
