Anode Lower Unit Bearing Housing aqxreight Aluminum 40/48/50 Motors

Description

Product Overview

The aqxreight Anode Lower Unit Bearing Housing is a precision‑engineered component designed to meet the exacting standards of marine propulsion systems. Constructed from high‑strength aluminum alloy, the housing offers superior resistance to the harsh corrosive effects of saltwater, brackish water, and freshwater environments. Its robust design incorporates reinforced wall sections and precision‑machined bearing seats that provide a stable platform for the lower unit bearings, reducing wear and extending service intervals. The part dimensions—7.87 x 5.91 x 1.18 inches—match the original equipment specifications, ensuring a seamless fit without the need for additional modifications. Weighing only 61 grams, the housing adds minimal weight while delivering maximum durability.

Every detail of this bearing housing has been optimized for performance. The aluminum material is treated with an advanced anodizing process that creates a hard, protective oxide layer, further enhancing resistance to pitting and galvanic corrosion. This protective coating also reduces friction at the bearing interface, contributing to smoother engine operation and lower fuel consumption. The housing is compatible with the OE part number 0398873, guaranteeing that it will replace the original component on 40, 48, and 50 two‑stroke outboard motors manufactured between 1989 and 2005. The part is listed under the best‑seller rank #18 in the Bearing Housings category, reflecting its popularity among marine technicians and boat owners.

Usage

This bearing housing is intended for use on a wide range of recreational and commercial vessels that rely on two‑stroke outboard engines. Whether you are operating a small fishing boat, a personal watercraft, or a larger utility vessel, the housing provides reliable support for the lower unit bearings, which are critical for propeller rotation and thrust generation. The component excels in both saltwater and freshwater applications, making it suitable for coastal cruising, inland lake use, and offshore excursions. Its corrosion‑resistant properties are especially valuable in tropical and subtropical regions where marine growth and salt spray can accelerate component degradation.

Installation is straightforward and can be completed by a qualified mechanic or an experienced DIY enthusiast. The housing is designed to bolt directly onto the engine lower unit using the factory‑specified fasteners, eliminating the need for custom adapters or additional hardware. Because the dimensions are identical to the original part, the alignment of the bearing seats remains true, preserving the engine’s balance and reducing vibration. Regular inspection of the anode bearing housing, combined with timely replacement, helps prevent premature bearing failure, which can lead to costly engine downtime.

FAQ

Is this bearing housing compatible with all 40, 48, and 50 two‑stroke outboard models?

Yes, the housing is designed to replace the original part number 0398873 on 40, 48, and 50 two‑stroke outboard motors produced between 1989 and 2005. Always verify the model year and engine specifications before purchase.

Do I need special tools to install the housing?

No special tools are required. The housing bolts directly to the lower unit using the factory‑specified fasteners. A standard socket set and torque wrench are sufficient for a proper installation.

How does the anodized coating improve performance?

The anodized coating creates a hard, protective oxide layer on the aluminum surface, which significantly reduces the risk of pitting and galvanic corrosion. This layer also lowers friction at the bearing interface, contributing to smoother engine operation and longer bearing life.

What warranty does aqxreight offer on this product?

We provide a one‑year limited warranty covering manufacturing defects. If the housing fails due to a defect within the warranty period, we will replace it at no additional cost.

Can I use this housing in freshwater environments?

Absolutely. The aluminum alloy and anodized finish are engineered to resist corrosion in both saltwater and freshwater, making the housing suitable for lakes, rivers, and inland waterways.
