It has been in the boat for 5 years and is still intact and working well.
It has been in the boat for 5 years and is still intact and working well. Clean lake and I've never sucked up sand or gravel. Just ordered another one.

good replacement at a good price
my original impeller finally gave out and I found this one for a excellent price. It works well and is pumping water through my Malibu and the engine no longer overheats. Thank you

Economy replacement.
Time will tell if this impeller is as good as it looks. Compared to the name brand, there is no apparent difference in size mater thickness and flexibility. Only gave 4 stars be cause it was just installed. If it makes it through a season of boating it will be a value replacement impeller. Installed on 351W Indmar where the Johnson pump is attached off the harmonic balancer.

Impressive durability vs. Johnson OEM
I just installed the 2nd impeller of this brand, meaning I just removed the 1st one after two years and 200 engine hours of service in my Indmar 320 LCR in my 2008 Malibu VLX. Not a single crack, chip or chunk out of the rubber fins. The brass hub looks great and rust free, and the rubber hub material looks brand new as well. For the price, I wouldn’t test this theory, but I would expect you could get 500 hours out of this impeller! Extremely impressed with the wear and durability. I won’t be going back to Johnson OEM rubber again.

2014 Moomba Mondo Indmar Assault 330
Update: 2025 2 seasons and 100 hours later! Here is what the impeller looks like. See pic! Still looks brand new! Almost felt bad swapping it out but I don’t dare go a third season with it. Rubber was a bit soft as expected after 100 hours of actual run time. I bought the same one as a replacement. What a win!Considering how expensive stuff has gotten I decided to buy this “off brand” impeller for our Moomba. Figured at this price I could replacement yearly (if need be) vs. every other year.What sold me was a review saying they had it for two years. I’ll update when I its time to replace it.Exact fit, exact look. Went in as any other one would. Fins felt pretty good.On the old impeller has 200+ hours on it. Not much wear.
