Im needing help finding the correct Impeller for my Mercruiser Raw Water Pump Model #46-72774

Hi there everyone,

Im so glad to see, that this site is still active.

Hopefully, someone out there can help me out.

I am wanting to change the impeller on my Mercruiser raw water pump, and can not find anything Listed for it, as this pump has been discontinued.


I just got back into Ski Boats and Bare Footing, after being away from it for 30 plus years, and am soooo Happy that I did.

What with COVID stopping us from Travelling, we rediscovered the Love of my Life, and that is Bare Footing and Skiing again, after thinking that I was done, with boats and Footing.

Thank You.....COVID! lol

So here is the issue.

I have a Mercrusier raw water pump on my 350, and am wanting to change the impeller in it, as it has not been done for the past 2 years....I bought the boat 2 years ago, when Covid hit us all.

The Model Number is a Mercruisier 46-72774 pump.....and I just can not find anything Listed for it, as that specific pump, has been discontinued.

Grrrrrrrrrr again!

Im guessing that from what I read, that Jabsco has a replacement pump for my Pump, if I was needing to replace the entire thing ( at a Cost of $1,200! OUCH) but....all I am needing is a $50 replacement Impeller.

Id Love you forever, if someone out there, can tell me, what Impeller I need for my Mercruiser 46-72774 Pump?

There has to be someone out there, with an Older Tournament Boat, who has the exact same water pump as I do, who can tell me....what Impeller to buy?

I would think, that most of the Older 351's and most 350's would run, the same size of Impeller in their pumps?

I am not even wanting to take it apart, until.....I have a New One on my Hand.....ready to go.

We leave in 3 weeks time, for 2 weeks of Footing and Skiing up at the Lake, and I was really wanting to put a New Impeller into her, before we go.

Im sure Hoping, that someone out there, can help me out....and tell me....what Impeller will replace mine?

I'll buy or 3 of them, once I can track down the correct size.

I Love having another older Tournament Boat, seems tough to find replacement parts now, that our boats are much we all are! LOL

I've been away from Footing for over 30 years now.....and its like I never ever left it!

Im now 67......( where did all of those years go too?) and I can still Fit into my Barefoot Company Barefoot suit...what are the chances of that? hahaha

Please ......Help me out if you can.

As I said previously....I'll Love ya forever!

    Welcome back to the water.
    Try these guys at this link If you don't see the one you need listed call them.
    Maybe @Jody_Seal or one of the other boat gurus can sort you out. Post a pic of the pump for reference.

    This Ebay offering looks pretty good. You get the complete pump rebuild kit for the price of an impeller. Link to the page here I have a friend with the same pump in his old boat and he is ordering one.
