Impeller for Selva 3.3/4 HP Outboards (Also 2.5 HP 4-Stroke)

Even the smallest outboard motors need reliable cooling – this impeller is specifically made for Selva’s 3.3 HP and 4 HP two-stroke engines, and it also fits the tiny 2.5 HP four-stroke model. These little outboards often power dinghies, canoes, or act as auxiliary motors, and they depend on water from the pump to keep the engine from overheating (since airflow alone is not enough at low speeds). A fresh impeller in the pump ensures water circulates properly through the engine.

Given the size of these engines, a failing impeller can quickly lead to overheating due to the small coolant volume. Replacing the impeller regularly is a wise practice to avoid being stranded with an overheated small engine. This replacement impeller matches the original Selva specifications (OEM 8095040), so you can restore your little outboard’s cooling system to full functionality with confidence. It’s an easy fix that provides big protection for your small motor.

• Ultra-Small Engine Cooling: Designed for Selva’s lowest horsepower outboards (2.5–4 HP), ensuring they receive the effective water cooling they require. Perfect for engines on inflatable dinghies, canoes, or other tiny vessels.
• Critical Maintenance: Tiny engines can overheat quickly; replacing the impeller each season or every ~50 hours is especially important for 3.3/4HP motors that often run at high throttle in hot weather.
• Compact but Durable: Despite its small size, the impeller is constructed from robust materials to handle continuous operation. The 6-blade design efficiently pumps water through the narrow cooling passages of the engine.
• Easy Installation: Swap out your old impeller with minimal tools. This part is a precise match for the Selva impeller (part 8095040 / CEF 500376), so installation is straightforward and the fit is exact.
• Confidence in Performance: With a new impeller, your little Selva engine can run smoothly for fishing, tender duties, or teaching beginners. Avoid engine failure by keeping your water pump in top condition with this replacement.
