Overview

The Jabsco 6760-0003-P is a nitrile flexible impeller kit for Jabsco Profile O pumps that use a 9-blade spline-drive impeller with a 3-3/4 in diameter, 3-1/2 in width, and 1 in shaft diameter.

This is a pump-fit replacement part, so the main checks are the impeller profile, blade count, drive style, and the three key dimensions rather than the boat model alone. The brass insert in the hub and the nitrile compound make it a practical match for flexible-impeller pumps used for engine cooling, bilge, transfer, and other general-purpose duties where this exact size is specified.

For buyers replacing a worn impeller before a trip or during seasonal service, the most useful fit reference is the old impeller or the pump data plate. The Profile O size also corresponds to 95 mm diameter, 88.9 mm width, and 25.4 mm shaft diameter.

Key features

• 9-blade flexible impeller with spline-drive hub for Jabsco Profile O pump applications
• Exact replacement size of 3-3/4 in diameter x 3-1/2 in width x 1 in shaft diameter
• Nitrile impeller compound for applications where oil contamination can shorten the life of a neoprene impeller
• Brass insert in the hub
• Suitable for flexible-impeller engine cooling, bilge, transfer, and general-purpose pumps that take this size

Compatibility and fit

This part should be matched by pump specification, not by appearance alone. On older boats and repowered boats, the same engine room can contain pumps from different series, so the safest check is the impeller profile, outer diameter, width, shaft diameter, and spline-drive hub.

It is a good match for owners, mechanics, and service yards replacing the exact Jabsco Profile O impeller size and wanting to keep the pump working as intended. It also makes sense as an onboard spare where loss of raw-water flow or transfer capability would stop the day.

Installation and service

When it is time to change the impeller, remove the pump end cover and pull the old impeller by the hub with the proper removal tool or pliers. Avoid levering against the pump body with screwdrivers, as damage to the cover face can lead to leaks.

Greasing the new impeller before installation helps it slide into the bore and gives it protection during the first prime. In marine service, this is the kind of maintenance part worth changing on schedule and keeping on board before the old impeller fails without warning.
