Fuel injector nozzle (marine) Yanmar S165 – YDL150T288SP | 139684-53010

Description

New fuel injector nozzle (tip) suitable for heavy-duty Yanmar S165 marine diesel engines. This 6-cylinder commercial Yanmar marine engine is used in fishing vessels, ferries, tugboats, offshore workboats, and as an auxiliary engine for marine generator sets. A correctly functioning fuel injector is essential here — disrupted atomization on these engines immediately costs power and fuel, and causes black smoke and increased emissions.

Exclusively from our own production line: a high-quality fuel injector nozzle that meets the strictest tolerances. This ‘Snelparts’ pintle nozzle was developed as the superior alternative to standard aftermarket parts and is perfect for overhauling your current fuel injector in the Yanmar S-series marine engine line.

We guarantee a perfect spray pattern and an exact seal, resulting in a smoother running engine and cleaner combustion. Advice from experience: don’t go for cheaper alternatives. Extensive research has been done into OEM quality, comparable to the well-known brands in this industry!
