Full StarEmpty StarEmpty StarEmpty StarEmpty StarDoesn'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

Full StarFull StarFull StarFull StarFull StarReplacement 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.

Full StarFull StarFull StarEmpty StarEmpty StarNot 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.

Full StarEmpty StarEmpty StarEmpty StarEmpty StarWhat 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.

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.
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.
