Description:

PP-119773-55750 Yanmar 119773-55750 / 119773-55800 Oil Cooler


This Seakamp Oil Cooler is a marine-grade replacement designed for Yanmar marine diesel engines installed in sailboats, motor yachts and commercial vessels, most commonly fitted to the 4LHA, 6LP family. The unit has a 2" x 5-1/2" core. It also replaces Yanmar part #119773-55800.


The oil cooler routes engine lubricating oil through a tube-and-shell heat exchanger where raw water (or, in some applications, engine coolant) absorbs heat from the oil before it returns to the engine's lubrication circuit. Maintaining stable oil temperature is essential for consistent viscosity, oil-film integrity and component wear protection.


Oil that runs too hot loses viscosity and protective film strength, accelerating wear on bearings, camshafts and turbocharger shafts. A correctly functioning oil cooler keeps oil in its design temperature band, extending oil service life and protecting the engine's most expensive internal components.


Manufactured to match OEM dimensions, port orientation and mounting geometry, the 119773-55750 is a true direct-fit replacement for the original Yanmar component. It installs without modification to existing hoses, brackets or pipework, making it suitable for planned maintenance, corrosion replacement or preventative servicing. The copper-nickel (CuNi) tube bundle gives superior resistance to seawater corrosion and electrolytic attack compared to standard copper, extending service life in tropical or high-chloride water.
