Description
Product Overview
The UANOFCN Water Pump Impeller Kit is a precision‑engineered replacement designed specifically for Mercury Mariner outboard engines of 30‑60 HP. Crafted from high‑grade neoprene rubber for the impeller, stainless‑steel wear plates, and a non‑asbestos gasket, the kit provides superior resistance to corrosion, heat and wear. Weighing only 1.41 pounds and packaged in a compact 6.34 x 4.84 x 3.7‑inch box, it offers a lightweight yet robust solution for maintaining optimal engine cooling. The kit includes all necessary components—impeller, O‑rings, gasket and wear plate—ensuring a complete overhaul in a single purchase.
Usage
Designed for 4‑stroke Mercury Mariner outboards (30, 40, 50 and 60 HP), this impeller kit fits the lower unit gearcase of models such as the Mariner 4‑Stroke 60 hp, EFI JET SeaPro, and BIGFOOT 3/4‑cyl engines. Ideal for both recreational boaters and professional marine technicians, the kit restores proper water flow to prevent overheating during prolonged runs, high‑speed cruising, or heavy‑load conditions. Before installation, verify the torpedo diameter (3.44 in / 87.38 mm) to ensure compatibility. The kit is unsuitable for 2‑stroke engines and for torpedo diameters that differ from the specified size.
Why Choose Us
UANOFCN combines marine‑grade materials with rigorous quality testing to deliver a product that meets OEM specifications. The neoprene impeller maintains flexibility across a wide temperature range, while the stainless‑steel wear plate resists abrasion from sand and debris. Our non‑asbestos gasket provides a reliable seal without the health concerns associated with traditional asbestos materials. Each kit undergoes a 100‑point inspection, guaranteeing fit, finish and performance that matches or exceeds the original equipment.

FAQ
What engine models are compatible with this impeller kit?
The kit fits Mercury Mariner outboard engines rated 30‑60 HP, including 4‑stroke models such as the Mariner 60 hp, EFI JET SeaPro, and BIGFOOT 3/4‑cyl engines. Verify the torpedo diameter (3.44 in) before purchase.
Can this kit be used on 2‑stroke engines?
No. This kit is specifically engineered for 4‑stroke engines. Using it on a 2‑stroke engine may result in improper fit and reduced cooling efficiency.
How do I know if the torpedo diameter matches my engine?
Measure the existing torpedo from outer edge to outer edge. The required diameter for this kit is 3.44 in (87.38 mm). If your measurement differs, select the appropriate kit with the correct torpedo size.
Is the gasket asbestos‑free?
Yes. The gasket is made from a modern, non‑asbestos material that provides a reliable seal without the health risks associated with asbestos.
What tools are needed for installation?
Standard marine tools such as a socket set, screwdrivers, and a torque wrench are sufficient. Detailed installation instructions are included in the package.
