The 4JH4AE Yanmar Marine Pumps are reliable, high-performance pumps designed for marine applications. They ensure efficient water circulation and cooling in marine engines. Built for durability, they withstand harsh marine environments.

The 4JH4AE Yanmar marine engine is a 4-cylinder, water-cooled diesel engine with a displacement of 1.642L. It produces 55 HP (40.5 kW) at 3000 RPM. The engine typically uses SAE 15W-40 or 10W-30 oil with an API grade of CF or higher. Viscosity should match operating temperatures. The engine block is made of cast iron, while components like the cylinder head are aluminum alloy. Marine pumps for this engine are usually bronze or stainless steel for corrosion resistance. Buoyancy is not applicable to the engine itself, but marine-grade materials ensure durability in wet conditions. The engine dimensions are approximately 690mm (L) x 520mm (W) x 600mm (H), with a dry weight of around 190 kg.
