Lower Unit Gear Oil Pump BFXM for Bottles 10cc Stroke 3/8″ Swivel

Description

Product Overview

The BFXM Lower Unit Gear Oil Pump is engineered for marine and small engine maintenance, specifically targeting standard quart bottles with 28mm caps. Each pump stroke delivers exactly 10cc of gear oil, providing consistent lubrication while minimizing waste. The unit includes a robust 3/8″ metal swivel adapter, interchangeable 8mm and 10mm rigid suction tubes, and a third‑hand adapter that secures the fill hose during operation. Constructed from high‑grade plastic, reinforced rubber seals, steel components, and an aluminum alloy housing, the pump balances lightweight handling with long‑term durability. Its compact package dimensions of 6.77 x 6.46 x 1.5 inches and a weight of just 2.89 ounces make it easy to store in a toolbox or on a workshop bench.

Usage

This gear oil pump is ideal for boat owners, outboard engine technicians, and DIY hobbyists who need a reliable method to refill lower unit gear boxes. The pump’s design allows installation without specialized tools; a simple screwdriver is sufficient to remove the engine cover and attach the adapter to the fill hose. Once connected, the user can operate the pump by hand, feeling the smooth resistance that indicates proper oil flow. The third‑hand adapter clamps the hose securely, preventing leaks during the filling process. Because the pump works with both 8mm and 10mm adapters, it accommodates a wide range of outboard models, except for Volvo Penta units. The low oil consumption and precise 10cc delivery reduce over‑filling risks, protecting seals and extending engine life.
