Neoprene water pump impeller 18-3306-Sierra
by Eugene from Elmira, New York on April 01, 2016
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.

I have been using these impellers for six years it is the right product at the right price. The impeller maintains it pliability so well that I now change it out every other year as opposed to annually in my 1995 220VRS Matercraft.

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!

No Gasket included
by Stephen from Lutz, Florida on August 02, 2012
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? I bought 2 of these to save on future shipping. Vendors should not sell parts without the required gaskets in order to have happy customers!

Q:
Does it come with any gaskets o rings to usewhen putting everything back together after install"?
A:
There are gaskets and such if you are replacing the water pump kit. So if you are taking apart the housing and such there are. If you are just replacing impeller then no. This impeller does not come with any other items, just the impeller.

Q:

A:
Yes this impeller will work for your Mercury V-135 1995 as long as your serial number fits the range of 0A904646 THRU 0C100860.
A:
Yes this is the correct impeller for your outboard.


Q:

Q:
I'm showing part number SP 685007 for my impeller on a 2005 Tige 22i Marine Power 5.7L, 350 hp, EFI will the 18-3020 work?
A:
It looks like the Marine Power used Johnson 09-812B pump which means you would need 18-3306 (dimater 2-1/4", side with 1-15/16"): http://www.iboats.com/Neoprene-Water-Pump-Impeller-18-3306-Sierra/dm/view_id.174178

We will need the engine gear ratio in order to match up the correct impeller. Let us know if you can provide that.


Q:
I have a 2009 50hp mercury outboard. I need an impeller but the serial number I have does not match any that I see for that HP. My serial number is 1B7727470?

Q:
Is this the right impeller for my 1990 Malibu with 350 FordMerc 5.7L?
A:
This is a aftermarket part. We need your engine serial number to look up a diagram of your engine to see if this part matches up to the OEM part number for your engine.
