Yanmar 4LV195 – Marine Diesel Engine 195 HP

Description

Provide auxiliary or primary shaft propulsion to your commercial hull with the Yanmar 4LV195. Generating 195 horsepower at 3500 RPM, this 2.755-liter displacement block delivers high continuous torque. High-pressure common-rail fuel injection cuts mechanical clatter at idle perfectly. Turbocharged intercooled air management maintains intake air density during continuous high-speed cruising. Forced enclosed lubrication utilizes an 8.5-liter oil sump. This actively protects moving components across varying dynamic operational loads. It eliminates the need for complex external air management setups inside small enclosed engine compartments entirely.

Raw seawater stays completely isolated from internal cylinder waterways thanks to the closed heat exchanger circuit. This 9-liter coolant system safely regulates internal block temperatures continuously. It permanently prevents internal salt scaling and heavy metal corrosion. The native SAE 4 flywheel housing mounts seamlessly to KMH50V hydraulic marine gears. Auxiliary electrical systems rely on the standard 12V 130-amp alternator output. Total dry weight registers at exactly 334 kg. Repower mechanics must factor this static physical mass into the vessel’s rear hull displacement center precisely.

Key Specifications of the Yanmar 4LV195 Inboard Diesel Engine

• This 2.755-liter 4-cylinder diesel pushes a verified 195 horsepower at 3500 RPM for heavy displacement and planning hulls.
• The common-rail direct fuel injection system accurately meters internal pressure, significantly dropping mechanical running noise and visible exhaust smoke.
• Turbocharged intercooled intake technology maximizes combustion oxygen density, maintaining highly responsive throttle performance throughout the entire mid-range operating speed.
• A closed freshwater heat exchanger isolates internal engine cylinders from raw seawater, preventing internal scale buildup and devastating salt corrosion.
• An onboard 12V 130-amp alternator pushes continuous electrical current to support heavy house battery banks and modern bridge electronics.
• The standard SAE 4 flywheel housing permits flexible coupling to KMH50V hydraulic marine gears and compatible ZT370 sterndrive setups.

Engine Operation and Output

Governed by strict electronic fuel mapping, this 2.755-liter Yanmar engine ensures exceptional physical power density continuously. An 8.5-liter oil sump guarantees forced pressure lubrication during demanding continuous offshore runs. The modern common-rail setup satisfies stringent EPA Tier 3, RCD II, and IMO II emissions limits globally. This happens by continuously manipulating fuel injection timing across the 1-3-4-2 firing order. Throttle synchronization runs directly through the digital VC20 electronic control network. This bypasses legacy mechanical push-pull cable friction issues during tight marina docking maneuvers safely.

Why Choose the Yanmar 4LV195 Inboard Diesel Engine

Fleet operators select the 4LV195 inboard diesel engine for its substantial 2.755-liter displacement and dependable 195 horsepower output. Electronic common-rail injection provides remarkably clean running conditions compared to older mechanically governed units. Featuring a substantial 130-amp alternator, it effectively sustains large DC refrigeration compressors or navigation screens. The SAE 4 flywheel housing adapts immediately to KMH50V hydraulic transmissions or heavy ZT370 sterndrives. Total dry weight remains strictly at 334 kg. This minimizes drastic center of gravity shifts inside your vessel’s engine room layout.

Installation and Alignment Considerations

Examine your engine bed stringers closely to determine precise 334 kg mount positioning tolerances. Mechanics must align the KMH50V transmission output flange directly to the propeller shaft within strict manufacturer parameters. Ensure your raw water sea strainers and wet exhaust piping comply with the exact flow volumes required for a 195 horsepower block. The water-cooled exhaust manifold strictly manages radiant engine compartment heat. It requires specific cooling water injection routing to prevent backward seawater flooding into the cylinders during sudden offshore engine shutdowns frequently.

Warranty and Support

This Yanmar propulsion unit features a standard Limited Factory Warranty covering major internal assembly defects extensively. Mulmarine.com provides essential product-information support before purchase and technical assistance with order-related questions. A thorough pre-shipment visual inspection confirms the crated engine item and all documented included components. Mechanics and vessel owners should examine warranty coverage scope concerning specific commercial versus recreational duty cycles. Please review the detailed warranty coverage and eligibility details directly on Mulmarine.com before placing your final heavy freight purchase order for this diesel block.

Before Ordering the Yanmar 4LV195 Inboard Diesel Engine

Check your engine room hatch opening carefully to confirm adequate fitting clearance for this 334 kg block. You must verify your intended transmission reduction gear ratio and existing shaft coupling dimensions. Confirm that your onboard DC wiring system safely supports a 12V 130-amp alternator charging circuit output. Next, ensure whether your helm station supports native VC20 electronic control inputs versus legacy mechanical push-pull cables. Guarantee your existing diesel fuel filtration system matches the precise EN 590 flow demands for common-rail injection networks effectively.
