Almost like the OEM except...
by Arthur from markham, Ontario on August 18, 2016
4th bolt (bottom left) had barely enough clearance for the socket to fit the bolt. Had to use an open end on a wierd angle to get enough torque. Also even though it fit accurately to the holes and gasket that was included, had to clean up some oversprayed paint on the brass surface prior to gasket sealer application. Haven't done a full load test in water yet, but the dockside run had to running smooth with no clearance problems with the other original parts (pulleys, belts, hoses etc).

Doesn't fit properly on 3.0L
by C from Marlton, New Jersey on July 23, 2016
Installed with new seals 3 times (big waste of $ and time). Each time it leaked at the third bolt. Also, pulley rubs on iron casing. Wasted 3 weeks out of water with bad part. I would buy the gm part...return approved for refund thanks to iboats

Replacement of 1984 water pump
by Donald from Winona, Minnesota on April 03, 2016
The online description was adequate to select the proper/correct water pump. My order was very promptly shipped with good packaging. I ordered it on a Tuesday morning and received the next day, Wednesday. The pump appeared to be a new pump and not a rebuilt. It is exactly what I needed. I have gotten items from iboats several times and have been very satisfied each time.

Not an exact fit.
by a Customer on July 27, 2011
Had to shim out the 3 gang pulley (power steer., impeller, water pump) to clear the new circ. water pump. Also had to remove the impeller pump bracket to allow clearance for the hose running from the thermostat housing to new circulating pump housing. Tripled time needed for simple replacement of circulating pump.

What Happened
by David from Montrose, Colorado on December 12, 2014
When opening the package I found a oversized cut down unmarked box inside a shipping box with packing around it. Good to this point, BUT when I opened the cut down box that had no labeling or ID I found the pump had been rattling around with no packing or bracing to contain it. It was shipping worn enough that I checked the shaft for true before repainting it! It did not contain ANY other items such as gaskets to mount it as pictured. I am very surprised at sierra for the condition or the packaging and product as shipped.

TIMING
by Jeffrey from Monarch Beach, California on September 23, 2012
OUR CUSTOMERS WERE SUPER UPSET, WHICH LED TO TWO BAD INTERNET REVIEWS ON THE INTERNET FOR OUR SHOP NOT IBOATS AND WE HAD NOTHING TO DO WITH IT! THANK YOU IBOATS!!! WE HAVE BEEN IN BUSINESS FOR OVER 40 YEARS AND THOUGHT WE WOULD USE IBOATS BECAUSE OF PRICING. WHY DID IT TAKE 2.5 WEEKS FOR PARTS TO GET TO US? PRICE GOOD, BUT NOT WORTH IT IF DONT HAVE TIME AND WE ARE A REPAIR SHOP. SUMMER IS ALMOST OVER. WE JUST CAN'T FIGURE OUT WHAT WOULD TAKE SO LONG TO PULL AN ORDER OR PART PUT IT IN A BOX AND SHIP IT TO US ON THE WEST COAST??? 5 DAYS OK BUT 2.5 WEEKS? OUR CREDIT CARD HAS BEEN GOOD FOR 40 PLUS YEARS?????????? WE LEARNED OUR LESSON AND WILL PAY MORE TO THE LOCAL DISTRIBUTORS JUST TO STAY OFF THE BAD INTERNET REVIEWS. IT WILL KILL YOUR CUSTOMER LOYALTY. THANKS FOR LISTINING JEFF MONROE RACING

Q:
Will this work on a 1997 FourWinns 195 Sundowner with a 4.3 GL Volvo Penta?
A:
We would need to know full model number or engine serial number to cross reference part. Example of VP model number is 4.3GLPLKD. Contact us at the number at the top of the page with that info and we can look into it.


Q:
My volvo penta aq 131d will fit this?
A:
No it will not. We only offer the OEM version which is part number 271975.


Q:
Is the gasket included?
A:
Yes it comes with the gasket.


Q:
Will this fit my 1988 3.0 the only numbers I can find are by the distributer (30 048RB) (1103693)?
A:
This will fit your motor figuring that you have the OMC engine.


Q:
What material is the impeller made from on this water pump?
A:
This does not take an impeller. This is the circulation pump, not the seawater pump assembly. We will need to know engine information to look up impeller.


Q:
Is the impeller different from an auto w/pump to a 302 ford mercruiser set up?
A:
We don't have a way of referencing water pumps to automobiles. We can only match up by marine application. If you need assistance finding the impeller for the seawater pump on your marine motor we can reference it by engine serial number.


Q:
Will this fit 1975 ford gt220 correct craft?
A:
We need more info about your engine to confirm if this will work. Please call or start a chat for assistance.


Q:
WILL THIS PUMP FIT MY 4.3L MERCMARINE ALPHA MOTOR?
A:
We will need to know the engine serial number to match up. Let us know if you can provide that.
