Merc kit by Michael - Nanticoke, PennsylvaniaJuly 29, 2010
Everything worked well with this kit, all parts matched perfect. The only thing that did not come with the kit was an impeller key, save your old one or buy a new one in addition to the kit.

Great Price, but... by a Customer - Miami, FloridaAugust 27, 2011
Unfortunately, the lower pump housing was not the correct one for my LU and was not available through iboats. Had to "special order" the correct one from my local marine store and ended up paying as much as if I had purchased everything locally. Otherwise, the rest of the parts in the kit worked out OK.

WOW! by a Customer - Miami, FloridaAugust 08, 2011
Even if this had been the only item I purchased, including shipping costs...I saved over half what the local marine outlets charge for these parts. OK, so it isn't a genuine, original, factory part...it will still do the intended job and it fits perfectly. Even the local marine store would have had to order the part, because they did not have it in stock. Iboats Marine store has great products at SUPER prices!

Water pump kit by John - Plains, GeorgiaJune 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.

Great parts. Great price by Joseph - Tallahassee, FloridaMay 04, 2012
Wish it included an assembly diagram. My motor is quite old and I am not sure everything was correctly assembled by previous person who worked on it.

Water pump for 40hp mercury tracker by Jeff - Spencer, West VirginiaApril 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

looks like OEM.but slightly out by Douglas - Howden, ManitobaMay 18, 2011
replaced this kit in place of the original.Found out the manufacturer didn't machine the tube opening deep enough to allow for water tube fron on top to drop into.Couldn't get my bottom unit bolted on,there was a gap of about 1/8 inch between bottom unit and upper.I had to drill with a flat bit 1/8 deeper into the pump upper tube housing.This wasn't a big thing to doas long as you have the right bit,otherwise one could force tighten the units together and probably crack the pump housing.Otherwise after this mod,everything went back together and pumps works good.

Water pump kit with housing by Andrew - Auburn, PennsylvaniaSeptember 01, 2013
Everything came promptly and was included, but housing was too large to fit correctly. Had to use the old one, now I have a spare that is too large for my motor. Wouldn't buy Sierra housing again, but everything else included was okay. I essentially overpaid for the items that were supposed to fit correctly and was only able to use wear plate, gaskets, boot, impeller, and bolts. Seems wasteful...

NOT A COMPLETE KIT by Joseph - Waterloo, IllinoisJuly 11, 2013
This product did not come with the base as described. I called customer service and was told it does not come with a base. I had to order one seperately at a cost of $26. Had I known this, I would have bought the Sierra kit, which only costs $10 more than the Mallory kit, and it comes with the base. I called Mallory and was told they do ship their kit with a base. It seems to me that iboats is screwing customers. I will not be purchasing any more from iboats.
