wrong part?
by Steve from Elk River, Minnesota on August 07, 2017
I ordered the replacement water pump impeller using the model number, serial number, and year of my outboard motor. I received the part in a timely matter. I then pulled the motor out of the water and begin the replacement process. Once I had the old one out I noticed the new one was 1/4" deeper then the old one. It fit in all other aspects, just too deep. So I went to the local parts store the next day. I used all the same numbers at the parts store and it resulted in the correct impeller. The parts store personnel and I still do not know why I was sent the wrong one. Also the bag the new impeller came in blew away so I did not send it back. Bummer cost me a day on the lake and 30.00 dollars.

I'm happy with the part. It came in three days like the women said it would. I forgot the women name I spoke to but boy o boy was she knowledgeable on my part that I ordered and then I asked her questions on a stainless steel prop or did she help me out with that with the pitch the size and everything else she was very very knowledgeable. I will definitely do business with these people again.

Works perfectly
by John from Lizella, Georgia on June 19, 2011
Double check the model number on your water pump and don't just go off the engine. Seems most people are unhappy because that's what they did. You have to pull the pump off anyway... Anyway, this impeller was a perfect fit and the o-ring that came was good as well. Also love how fast iBoats ships stuff!

I have bought many of these for my 1991 bost over the years. This is the first one that has NOT included the required gasket. What do I do now that I need the gasket?
