Yamaha Haima 2 Hp 3.5 Hp Water Pump Impeller – DingDing168 Easy

Description

Product Overview

The DingDing168 water pump impeller is a precision‑engineered component designed specifically for Yamaha Haima outboard engines rated at 2 Hp and 3.5 Hp. Constructed from high‑grade polymer material, the impeller offers exceptional resistance to corrosion, abrasion, and the harsh marine environment. Its compact dimensions—0.39 × 0.39 × 0.39 inches—allow it to fit seamlessly into the existing pump housing without requiring any modifications. Weighing only 1.76 ounces, the impeller adds minimal weight to the hull, helping to improve overall vessel balance and fuel efficiency. The design incorporates a series of finely machined vanes that promote rapid water circulation, reducing engine temperature and extending the life of critical components. Compatibility is guaranteed with the OEM part number 646‑44352‑00, ensuring a direct replacement that meets or exceeds original performance specifications.

Usage

This impeller is ideal for a wide range of marine applications, from small recreational boats and fishing vessels to personal watercraft and utility craft that rely on Yamaha Haima outboard powerplants. Whether you are operating in calm inland lakes, brackish estuaries, or open‑sea conditions, the DingDing168 impeller provides consistent cooling performance, preventing overheating during prolonged runs or high‑load scenarios. The lightweight nature of the component makes it especially suitable for vessels where weight distribution is critical, such as racing skiffs or lightweight tenders. Installation can be completed by a qualified technician or an experienced DIY enthusiast in under fifteen minutes, thanks to the tool‑free mounting design and the inclusion of clear alignment markings. The low‑noise operation ensures a quieter ride, enhancing passenger comfort and reducing acoustic disturbance in sensitive environments like wildlife reserves or residential marinas.
