Looks like OEM part
Excellent Impeller for the money. Consider buying an Impeller Kit if you haven’t changed the gaskets in a few years.

It fits my 2 hp Nissant
It was a very good price and it fit my engine. Now if I can get the engine back together I will be able to tell how well it works. The difficulty in reassembly has nothing to do with the impeller.

Original part on the left fits on the propellor shaft. Smaller one on the right runs on the the vertical shaft. They must be ordered by model number.
