Reliable replacement impeller
Second time purchasing this impeller kit. I replace the impeller every other year, at the beginning of the season. Works well and has been reliable, so far. Installed in the Johnson water pump on the Indmar Monsoon 340. I've used all kinds of tools and methods to remove these over the years. An impeller puller is definitely the easiest. Just need a little soap or water-based lubricant to ease the installation.

Perfect fit for my 1992 Mastercraft Prostar 190. Easy to install and just like the OEM.

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.

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

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.

Not for a 1977 Chrysler 75hp outboard. My bad.
It's hard to find parts for much older engines. I took an chance that this might fit a 1977 Chrysler 75 outboard. It's too big (too deep) and has fewer blades. The cost of this part is reasonable to it was worth the chance. Not disappointed in the vendor.

Packaging and Quality
I purchased both OEM and this product. The quality appears to be good. It was delivered on time and included the impeller, o-ring and gasket plus customer support contact information email. Absent was lubricant. I compared to a new OEM impeller and noticed that the rubber was a bit softer and it does not have a notch near the spline like the OEM version. Have not installed yet.
