    Perfect fit - 2004 Merc 150 XR6
    by David from Manassas, Virginia on February 11, 2016
    Excellent product and fast shipping. Nice that includes ALL the parts to do a complete rebuild and install. Some kits do not include the lower housing. Only reason for 4 stars is that the kit supports several models and its a little difficult to tell which washers to use for a specific engine model. Gaskets are not a problem just be sure you view on-line videos and check reference manuals. A cross referenced parts list with sheet that details and identifies all the parts and washers would be helpful. One other item that would be nice to include would be a little grease for the washer set but that is easily ordered on-line.

    Merc 2000 150 XR6
    by John from Florence, Mississippi on December 01, 2015
    Went on fine. Just like oem. Allot of extra O rings (generic fits several models) this caused me to second guess my job. I suggest take pictures or make list when taking old one off. Once you've done it once it's an easy job. Fast shipping great price.

    Not quite right
    by James from Air Ronge, Saskatchewan on July 10, 2013
    This water kit for my 70's Mercury 115 hp motor was almost it. For some reason the base is too big and I had to use the old base. I did not see the "key way" when I took it apart and there is no new one in the kit. Now I have to search around trying to find one at dealers to put this together. Did expect these problems when I started this rebuild. Jim Lennard Shellbrook, Canada

    Great Price, but...
    by a Customer from Miami, Florida on August 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.

    by a Customer from Miami, Florida on August 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!

    Bought my first boat and she needs a lot of work. I'm in love.

Plenty more business where this came from iboats and it's all yours. Thanx. P.S. She's a '79 MFG Gypsy 14 and the custom parts you still have available give me that warm fuzzy feeling...wink

    by Alex from Bloomington, Minnesota on May 26, 2011
    I could only use the top piece gaskets and 2nd oil seal as I have an older model that is a few years out of range for this kit. They don't make one for mine. But it all went together and is holding up well. Glad I found this kit as parts are harder to come by for the older unit.

    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

    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.

    A Relatively Minor Gripe
    by Arthur from San Diego, California on February 08, 2015
    For my motor (30 HP Mariner, 1982) the bottom plate supplied with the kit had the intake slot about 1/2 the size of the one that I was using. Installed it anyways and, yep, 1/2 the intake = 1/2 the flow :( Old plate wasn't in bad shape so I used it to scribe the intake slot onto the new plate. Re-installed the old plate. I'll drill/Dremel out the slot in the new plate at my leisure and use it as a backup. Not a big deal - at the age of my motor I'll take what I can get. All the other components of the kit were top notch.

    Water pump 1985 Matiner outboard Staff confused cost me $17
    by Daniel from Stillwater, Minnesota on July 21, 2014
    Water pump 1985 Matiner outboard Staff confused cost me $17 in extra shipping and could of cost me a total of $72 + $17 = $89 more. If I did not receive and have both water pumps 18-3426 and 18-3427 to compare with each other and the original I would have spent $140 instead of $58. Everyone was saying the 18-3426 was the one for my outboard at $123 even after I said the serial # fits the discription of the 18-3427. So when I had the both here I found the 18-3427 match the original and sent back the 18-3426 for refund which cost me the extra $17 and time with your recomendation/advice. The 18-3427 works great. Note sure how you could justify the differnce in price with so little difference in product?????????????

    Water pump kit with housing
    by Andrew from Auburn, Pennsylvania on September 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...
