Jabsco Impeller Kit, Double Flat Drive, 12-Blade, Neoprene, 3-3/4 in Diameter, 3-1/2 in Depth, 1 in Shaft Diameter, Plastic Insert

Overview

The Jabsco 17370-0001-P is a 12-blade neoprene impeller kit for flexible-impeller pumps that use a Q-profile impeller with a double-flat drive. Its key fit points are a 3-3/4 in outside diameter, 3-1/2 in depth, a 1 in shaft size, and a plastic insert.

This is the style commonly used in raw-water engine cooling and other water-transfer pump service where the pump is built around this exact hub shape and impeller size. Neoprene is the standard compound for fresh and salt water duty, so the main buying check is mechanical fit: profile, diameter, depth, shaft size, and drive style all need to match the pump already on the boat.

Key features

• 12-blade neoprene impeller for fresh and salt water pump service
• Q-profile body with a 3-3/4 in outside diameter and 3-1/2 in depth
• 1 in shaft size with a double-flat drive
• Plastic insert that matches pumps built for this hub style
• Kit format suited to scheduled service and keeping a ready spare on board

Compatibility and fit

Fit depends on the pump, not just the engine brand. Before ordering, match the old impeller or pump service data for the Q profile, 12-blade count, 3-3/4 in diameter, 3-1/2 in depth, 1 in shaft size, plastic insert, and double-flat drive. A difference in any one of those points can stop the impeller from seating correctly or from driving on the shaft.

This is a good match for boat owners maintaining a larger raw-water pump on an inboard diesel installation or carrying a spare for longer runs. On boats where engine cooling depends on a flexible impeller, having the exact replacement on board can save a trip from turning into an overheating problem.

Installation and maintenance

When it is time to service the pump, remove the cover and pull the old impeller from the hub instead of levering against the pump body. A light coat of impeller lubricant before startup helps the new impeller slide into the bore and protects it during the first prime. Replacing the cover gasket at the same time and checking for any missing vane pieces helps prevent leaks and downstream blockages.

Flexible impellers are wear items. On boats that see regular engine hours, seasonal layups, or long periods of idle time, routine inspection and scheduled replacement are a better approach than waiting for a loss of water flow underway.
