Jabsco Engine Cooling Water Pump, For MerCruiser, 1-1/4 in Hose Barb, Bracket Mount, Bronze Body

Overview

The Jabsco 43210-0001 is a bracket-mount engine cooling water pump for MerCruiser inboard and stern drive engines that replaces Quicksilver 46-72774 A32. It uses 1-1/4 inch hose barb ports and is rated for 20 GPM at 1500 rpm.

The one-piece bronze body, neoprene impeller, stainless steel shaft, lip-type seal, and twin single-row ball bearings fit the raw-water side of an engine cooling system. A replaceable wearplate keeps routine service more practical when the pump is opened for impeller work.

Key features

• Direct replacement for Quicksilver 46-72774 A32 on compatible MerCruiser inboard and stern drive engines
• Bracket-mount layout fits either the cast iron clamp-type bracket or the stamped steel bolt-on bracket used on this application
• Works with left-hand or right-hand engine rotation and accepts stock MerCruiser drive pulleys
• 1-1/4 inch hose barb ports match the standard hose size used on this pump
• 20 GPM flow rating at 1500 rpm
• Bronze body with neoprene impeller, stainless steel shaft, lip-type seal, twin single-row ball bearings, and replaceable wearplate

Compatibility and fit

This pump follows the MerCruiser bracket-mount layout rather than a generic flange pattern, so the key fit points are the bracket style, pulley arrangement, and hose size. The lower port is the inlet and the upper port is the outlet. It accepts stock MerCruiser drive pulleys, but the pulley and the four pulley fasteners are separate items during installation.

It suits replacement work on boats that already use the Quicksilver 46-72774 A32 pattern and need to keep the original bracket and belt-driven setup. That makes it a practical match for many inboard and stern drive engine rooms where service access and parts interchange matter more than changing the whole pump arrangement.

Installation and service

On stamped steel brackets, mounting uses three 5/16-18 x 3/4 inch hex screws and three 5/16 inch lock washers that come with the pump. On cast iron clamp-type brackets, the pump slides into the bracket and is aligned to the pulley before the clamp is tightened.

The end cover can often be reached for impeller service without changing the whole installation layout, and the replaceable wearplate helps when internal wear starts to affect pump performance. On engines with a transmission cooler, the end cover also includes a 1/8 inch pipe plug connection for the cooler feed line.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
