Description

BROAD COMPATIBILITY: Fits 1970–1990 MerCruiser Pre-Alpha, R, MR, and Alpha One (Gen I) Sterndrives. Also fits various Mercury and Mariner outboards from 65 HP (4-cylinder) up to V6 models (135 HP–220 HP) utilizing a short-vane impeller.

CRITICAL FITMENT NOTE: This kit is designed for classic Generation 1 drives with a 2.356" diameter base. It WILL NOT fit Alpha One Gen II drives (1991 and newer, typically identified by an in-boat gear oil reservoir) or drives with a Vertical Shaft Preload Pin.

MARINE-GRADE DURABILITY: Built for harsh saltwater and freshwater environments. Features an upgraded EPDM rubber impeller for maximum heat and wear resistance, and 316 stainless steel wear plates and cups to prevent corrosion.

COMPLETE REPAIR SOLUTION: Everything you need for a total lower unit cooling system overhaul in one box.

DIRECT REPLACEMENT: Engineered to meet or exceed OEM specifications. Directly replaces Mercury/MerCruiser OEM numbers 46-44292A5, 46-96148A8, and aftermarket part numbers Sierra 18-3320, GLM 12120, and Mallory 9-48307.

Protect Your Engine with the FASWORX Complete Water Pump Repair Kit Overheating is one of the leading causes of marine engine failure. A compromised water pump can quickly leave you stranded or cause thousands of dollars in engine damage. The FASWORX Water Pump Impeller Repair Kit with Base is precision-engineered to restore your lower unit’s cooling system to peak performance, ensuring proper water flow and pressure. Designed as a direct drop-in replacement for MerCruiser Alpha One Gen 1 and high-horsepower Mercury outboards, this kit eliminates the guesswork of mixing and matching parts. Why Choose FASWORX? We don't cut corners on materials. Standard aftermarket kits often use cheap rubber and basic steel that degrades quickly. FASWORX utilizes EPDM rubber for the 6-vane impeller, preventing the "heat-set" and cracking that ruins lower quality impellers. Our wear plates and insert cups are forged from 316 Stainless Steel, providing ultimate defense against saltwater corrosion. The housing and base are constructed from high-impact polymers capable of withstanding extreme pressure and heat. Compatibility Guide: MerCruiser Sterndrives: Pre-Alpha (MC-I, R, MR) and Alpha One Gen I (1970–1990). Note: Must be a standard #1 lower unit without a preload pin. Mercury/Mariner Outboards: 65 HP – 140 HP (4 & Inline-6 Cyl) and V6 Outboards (135 HP – 220 HP). Note: Must require a short-vane impeller. IMPORTANT WARNING: Do not purchase this kit if you have an Alpha One Gen II drive (1991+). If your boat has a transparent gear oil reservoir bottle mounted inside the engine bay, you have a Gen II drive and this kit will not fit. Replaces Part Numbers: OEM: 46-44292A5, 46-96148A8, 46-96148A5, 46-96148A1, 46-44292A3 Sierra: 18-3320 GLM: 12120 Mallory: 9-48307

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $3 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for FASWORX products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
