Not happy
by Donald from Mio, Michigan on June 17, 2015
The bottom gasket was to small to fit on the water pump, the kit had two gaskets in it and both of them split while trying to install had to use old gasket w/ silicone not happy !!

over all good product
by Donald from San Antonio, Texas on May 30, 2014
contained everything needed. only problem i had was the upper houseing was difficult to install on the alignment pins. i think if the holes were drilled a little larger it would have helped.

Wrong Kit
by E-J from Mattawan, Michigan on May 22, 2014
iBoat customer service was great but their parts selection failed. I ordered a pump kit based on Brand, HP, year, of OB motor and the main pump kit generic picture showed what I wanted but I received a complete different kit (shown here). There is nothing wrong with this kit it just didn't fit my outboard. Customer service was very helpful in determining they can't offer a kit for a 60HP Merc. Bigfoot ELPI outboard. This did cost me shipping to me and shipping back to iBoats negating the good price as that was a $18.40 mistake? Again the partnumber selection leaves something to be desired but the part itself looked fine.

Water pump for 40hp mercury tracker
by Jeff from Spencer, West Virginia on April 06, 2014
I recently bought a 1996 Bass Tracker with a 40hp Mercury Tracker motor on it. It did not have the serial number plate on it.I emailed iboats and they researched the information i was able to give them and found the correct water pump for me. iboats emailed me just as if i were a customer standing in the iboats store. Even though it was an email i the customer,was their priority. Thank you iboats for the great customer service you provided me. I will be a return customer. Thank you, Jeff

water pump kit
by James from Ogden, Utah on September 09, 2012
Only criticism I have is that there was no schemetic / parts list with thte order. I am 82 years old, background in engineering, have a manual but they are very general. Without a parts list / schemetic I have no real way of knowing if the kit is copmplete ... otherwise am totally satisfied with your service and delivery ... Jim Morkin

Water pump kit
by Steve from Council Bluffs, Iowa on July 20, 2012
Ordering was a little difficult until I was connected with a representative who was able to help find the kit for my older Mariner outboard. I received the parts in a couple of days and managed to make the repair with the help of a friend(no instructions).All,s well that ends well. I have previously purchased a boat cover and prop. from iboats so I'm sticking with you. Steve Mether
