Yanmar 6LY2A-UTP 370HP Inboard Diesel Marine Engine

Description

The Yanmar 6LY2A-UTP 370HP Inboard Diesel Marine Engine eliminates frustrating power lag and sluggish acceleration tracking on heavy planing family cruisers, custom sportfishing express layouts, and commercial utility pilot boats. Running on standard number 2-D marine diesel, this heavy-duty four-stroke engine coordinates direct mechanical injection via high-pressure in-line pumps to replace complex electronic setups entirely. Vessel skippers can navigate rough open seas confidently, letting the high-tonnage turbocharged induction system generate consistent high torque lines flawlessly up to a 3300 RPM full throttle range.

Constructed with a freshwater cooling system via a heat exchanger with raw water internal loops, the vertical inline-six block prevents internal hot spots inside unventilated engine beds. The robust 5.813-liter engineering architecture delivers an intense 370 horsepower crankshaft output, managing electrical parameters via an integrated 80 Amp at 24 Volts standard charging array. Procuring this premium Japan-manufactured marine diesel engine optimizes structural power-to-weight reliability, backed by a comprehensive 2-Year limited pleasure marine factory warranty plan.

Key Features of Yanmar 6LY2A-UTP

• Inline 6-Cylinder Four-Stroke Vertical Marine Diesel Engine links a high-torque 5813 cc cylinder layout with direct mechanical injection to secure elite mechanical reliability.
• Turbocharged with Intercooler High Tonnage Induction System forces high-boost charge air into combustion chambers forcefully to generate instantaneous low-end acceleration.
