Quicksilver water pump impeller 47-161543 for Mercury and Mariner outboard motors is an original impeller for the engine's water pump. The six flexible blades circulate cooling water through the engine's cooling system, thereby helping to protect the engine against overheating.
The impeller has an outer diameter of approximately 33.6 mm, a height of approximately 14.35 mm, and a shaft bore of approximately 10.35 mm. The dimensions should be compared with the existing impeller and the engine's spare parts catalog before installation.
The spare part is documented for selected Mercury and Mariner outboard motors of 2, 2.5, 3.3, 3.5, 4, 5, and 6 hp. Compatibility includes both 2-stroke and 4-stroke engines but depends on engine type and serial number. Documented applications include 2-3.5 hp with relevant serial numbers starting from 0G710613, 0P017000, 0P401000, 0R131842, 0R568285, 0T884302, and 0T894577.
For 4 and 5 hp, compatibility includes selected 2-stroke engines from serial numbers 0G710613, 0P017000, 0P401000, and 0T894439, as well as selected 4-stroke engines in the ranges 0P073456-0P400999, 0P401000-0R411837, 0R000001-0R067089, 0R067090-0R411837, and 0R411838 and up. The 5 hp 4-stroke JCI from 0R560794 and 6 hp 4-stroke in the documented 0P and 0R serial number ranges are also included.
