Twin outlet port pumps offer the convenience of using only one intake for both the livewell and raw water washdown pump. A 3/4" tapered inlet connects directly to the seacock. Provides a continuous flow of water discharge to the livewell while the lower outlet port connects to the washdown pump through either 1/2" or 3/4" ports. (Model 10289817, 1250 GPH, has 1-1/8" ports.) Single-port livewell pumps in 500 GPH and 750 GPH capacities feature smaller profiles to fit in more confined spaces. Easy to change motor cartridge.
