Product Details

The Johnson Pumps 10-24904-12 is an OEM-quality flexible impeller pump designed specifically for select Nanni diesel marine engines.

Johnson Pumps flexible impeller pumps are trusted by boat builders and marine mechanics worldwide for their durability and long service life.

Great shopping experience!

Good service, good delivery.

Easy to find merchandise that no one else has

Pump connection wires look weak, and box it arrived in was a bit beat up. Overall, the pump looks good, but I am suspect about the wire connections. They look weak and prone to breakage. Looks like they have been refurbished. Was purchased as a gift, so the receiver of pump will need to determine its quality.
