Parts Desk Insight — Best Use
The Proline 22502 is the right call for small boats, tenders, and shallow bilge compartments where a compact footprint matters as much as output. At 500 GPH it handles normal seepage and minor ingress reliably without over-speccing for the application. The water-cooled motor gives it a durability edge over air-cooled pumps in warm, enclosed bilges. Recommend pairing with a float switch for automatic operation — or step up to the 22702 (750 GPH) if the customer has any history of faster water ingress or a larger bilge volume.
