Jabsco 4528-0001-P Neoprene 6-Blade Impeller 1-9/16″ for Boat Pumps

Description

Product Overview

The Jabsco 4528-0001-P neoprene impeller is a precision‑engineered component designed to replace or upgrade the impeller in marine water pump systems. Constructed from high‑grade neoprene, the impeller offers superior resistance to oil, fuel, and saltwater corrosion, extending service life even under demanding conditions. Its six‑blade configuration creates a balanced, high‑flow water pattern that maximizes cooling efficiency while minimizing cavitation. The 1‑9/16″ diameter matches the standard bore size for most boat water pumps, ensuring a direct, interference‑fit installation without the need for additional machining. A brass insert is integrated into the hub, providing a durable, wear‑resistant bearing surface that maintains alignment and reduces friction during operation.

Dimensions are carefully controlled: the impeller measures 3/4″ in width and shaft diameter, with a total outer diameter of 1‑9/16″. The compact profile allows it to fit within tight pump housings while delivering the required volumetric flow. The product package dimensions are 6 x 4 x 1 inches, and the unit weighs only 0.1 kilograms, making it easy to handle and store on board. The part number 45280001P corresponds to the 2013 model year, and it is compatible with a wide range of Jabsco and other OEM pump assemblies used in recreational and commercial vessels.

Usage

This impeller is intended for use in marine environments, specifically for boat engine cooling systems that rely on water pump circulation. It is suitable for both fresh‑water and salt‑water applications, making it a versatile choice for inland lakes, coastal cruising, and offshore voyages. Installers should ensure the pump housing is clean and free of debris before fitting the new impeller. Greasing the neoprene surface with a marine‑grade lubricant can ease installation and provide an additional protective layer during the initial priming phase. Once installed, the impeller will maintain consistent water flow, preventing overheating and protecting critical engine components.

Regular maintenance schedules recommend inspecting and replacing impellers at least once per year, or more frequently if the vessel operates under heavy load or in harsh conditions. Keeping a spare impeller on board is a prudent practice, as a failed impeller can lead to rapid engine overheating and potential damage. The Jabsco 4528-0001-P is designed for quick swap‑out, allowing boat owners or service technicians to perform replacements with minimal downtime.

FAQ

What vessels are compatible with this impeller?

The Jabsco 4528-0001-P is compatible with a wide range of recreational and commercial boats that use standard 1‑9/16″ water pump bores, including outboard, inboard, and sterndrive engines.

How do I install the impeller correctly?

First, clean the pump housing and ensure the bore is free of debris. Apply a thin layer of marine‑grade grease to the neoprene surface, then align the brass insert with the pump shaft and press the impeller into place. Verify that the impeller sits flush and rotates freely before reassembling the pump.

Can I use this impeller in a salt‑water environment?

Yes, the neoprene material is formulated to resist saltwater corrosion, making it suitable for both fresh and marine applications.

How often should the impeller be replaced?

It is recommended to inspect and replace the impeller at least once a year, or sooner if you notice reduced water flow, unusual noises, or signs of wear during routine maintenance.

What warranty does Jabsco provide?

Jabsco offers a limited warranty covering manufacturing defects for a period of one year from the date of purchase, along with access to technical support for installation and troubleshooting.
