Jabsco Profile B Flexible Impeller, 8 Blade, 1-1/4 in Dia, 15/32 in Width, 5/16 in Shaft, Single Flat Drive

Overview

The Jabsco Flexible Impeller, Profile B, Size 005 is a replacement flexible impeller for small marine pump applications where the existing impeller matches Jabsco Profile B and size 005. This profile uses 8 blades, drive type 4, a brass insert, a 1-1/4 in. diameter, a 15/32 in. depth, and a 5/16 in. shaft diameter, giving buyers the key measurements needed before opening the pump cover.

This impeller range is used in flexible impeller pumps on boats for raw-water cooling, water transfer, bilge pumping, and service pumps, depending on the material selected. Matching the material to the fluid matters: neoprene is the common choice for engine cooling and fresh or salt water transfer, while nitrile is used where the pumped water may contain heavier oil or diesel contamination.

Key features

• Profile B, size 005 impeller format for matching against the existing pump impeller or Jabsco selection data.
• 8-blade flexible impeller with a 1-1/4 in. diameter and 15/32 in. depth for compact marine pump bodies.
• 5/16 in. shaft diameter with drive type 4 and a brass insert for the correct mechanical engagement in compatible pumps.
• Material options cover common boat service needs, including neoprene for raw-water cooling and nitrile for contaminated bilge or transfer duties.
• Useful as a planned spare for cruising, fishing, and seasonal maintenance where a worn impeller can quickly stop cooling or pumping performance.

Variants

This product is offered in two material configurations so the impeller can be matched to the fluid being pumped and the job it performs on board.

The size, profile, blade count, drive type, shaft diameter, diameter, depth, and brass insert are consistent across these two variants. The material is the changing attribute, and that choice affects where the impeller is best used in the boat system.

• 14750-0001-P, Material: Neoprene. Neoprene suits engine raw-water cooling and fresh or salt water transfer where only small amounts of oil or diesel may be present.
• 14750-0003-P, Material: Nitrile. Nitrile suits bilge and transfer applications where the water may be heavily contaminated with oil or diesel.

Compatibility and fit

Before ordering, compare the removed impeller with the required Profile B shape, drive type 4 hub, 8-blade layout, and the listed dimensions. A close visual match is not enough on its own, because shaft diameter, depth, and drive style all affect whether the impeller will seat correctly and turn with the pump shaft.

This is a practical spare for boat owners maintaining small flexible impeller pumps, especially where access is limited and a failed impeller would interrupt engine cooling, transfer work, or bilge service. Keeping the correct material on board helps avoid using a cooling impeller in a contaminated-water job, or the wrong impeller in a raw-water cooling pump.

Installation and maintenance

Inspect the old impeller for missing vanes, cracking, swelling, or stiffness before fitting the replacement. Any missing rubber pieces should be traced through the pump outlet and downstream plumbing so they do not restrict cooling water or reduce pump flow.

During installation, lubricate the impeller and pump cavity with water or a suitable impeller lubricant, then rotate the impeller into the housing so the vanes fold in the correct direction. Check the cover gasket or sealing surface before reassembly, and run the pump only with liquid present, since a dry flexible impeller can be damaged quickly.
