    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.

    Full StarFull StarFull StarFull StarFull StarWorks 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? 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:
    What is dia. of center hole and width of fins?

    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

    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?

    The replacement impeller that pulls up for your Mercury engine is this one: http://www.iboats.com/Water-Pump-Impeller-18-3056-Sierra/dm/view_id.172244
