Attwood Marine Aerator Remote Mounting Bracket, Black Plastic

Overview

This Attwood Marine aerator remote mounting bracket is a black plastic bracket used to mount an aerator pump to a base away from the transom. It gives the pump a supported mounting point when the plumbing layout, service access, or boat structure calls for a remote location instead of a direct transom-mounted setup.

The bracket is offered in two size options, 1-1/8 in. and 3/4 in., so the correct version can be matched to the pump connection size used in the livewell or baitwell aeration system. It is a practical replacement or installation part for small boat, fishing boat, and livewell pump layouts where keeping the pump secure matters as much as keeping the hose run clean.

Key features

• Remote mounting bracket for attaching an aerator pump to a base away from the transom.
• Available in 1-1/8 in. and 3/4 in. sizes to match common aerator pump connection sizes.
• Black plastic construction suits livewell and baitwell pump areas where the bracket may see moisture and routine washdowns.
• Useful when pump placement needs better access for service, hose routing, or clearance around the transom area.
• Simple bracket format keeps the installation focused on fit, pump support, and clean plumbing layout.

Variants

This product is offered in multiple configurations based on the aerator pump size used in the installation.

The size is the key difference between the variants. Both versions are black plastic remote mounting brackets used to mount an aerator pump to a base away from the transom.

• 4121-3, size 1-1/8 in. This version fits aerator pump installations that call for a 1-1/8 in. bracket size, which is commonly selected around the pump and hose connection already on the boat.
• 4122-3, size 3/4 in. This version fits aerator pump installations that call for a 3/4 in. bracket size, making it the smaller option in this bracket range.

Installation and fit

Before installation, confirm the aerator pump connection size and check that the mounting base is flat, secure, and positioned where the pump can be reached for service. The bracket is intended for remote pump placement, so it can help clean up the layout when the transom area is crowded or when the pump needs to sit closer to the livewell plumbing path.

Leave enough clearance around the pump for hose bends, clamps, wiring, and future removal. On fishing boats and small utility boats, this kind of bracket is especially useful in bilge, stern, or livewell compartments where space is tight and the pump needs to stay firmly located while the boat is running.

Use cases on board

This bracket is a good match for boat owners replacing a worn pump bracket or setting up an aerator pump in a livewell or baitwell system where a remote mounting point makes more sense than mounting directly at the transom. It is most relevant for installations where the pump size is already known and the main goal is a secure, tidy pump location.
