Benefits of LSV-Based Jethrow Engines

Versatility and Proven Performance

  • Factory Fresh: Our engines are assembled using brand new parts sourced from OEM suppliers, ensuring reliability and longevity.
  • Wide Application: LSV engines are commonly used in various high-load applications, such as trucks, forklifts, and vans, where they perform reliably over hundreds of thousands of miles.
  • Marine Proven: These engines power boats effectively, including replacing standard 4.3 Mercruiser engines, where they run smoothly at 4200 RPM for thousands of hours.

Advanced Cooling Technology

  • Oil-Spray Piston Cooling: Equipped with six oil-spraying jets, our engines provide an extra layer of cooling and friction reduction. This feature cools the pistons and cylinder walls, enhancing durability and performance, particularly under heavy loads.

Key Benefits:

  • Longer Reliability: The cooling system ensures better lubrication of piston walls, extending the time between overhauls and allowing for higher power outputs if needed. This feature, originally developed for high-performance race car engines, now benefits marine applications by increasing reliability and power potential.

High-Performance Components

  • Rotating Assembly and Windage Tray: Our engines feature a robust rotating assembly, including a steel crankshaft and high-strength aluminum-alloy pistons. The lightweight pistons enhance high-RPM performance, while the nodular main bearing caps and redesigned windage tray improve oil flow and crankcase breathing.

Enhanced Oiling System

  • Advanced Oiling System: The dual-pressure-control and variable-displacement vane pump, along with the efficient use of thinner 5W30 oil, ensures optimal lubrication and efficiency. This system supports both high-performance and low-RPM operation, adapting to the demands of the engine.

Modern Versus Legacy Technology

  • Modern Engineering: Our engines incorporate modern technologies like liquid cooling and four valves per cylinder, contrasting with older, less efficient designs. These features contribute to superior real-world performance and efficiency.

Performance Metrics

  • Powerful and Lightweight: Jethrow engines offer outstanding performance with options like 375 HP naturally aspirated engines and 600 HP turbocharged versions. They provide unmatched power-to-weight ratios, making them ideal for high-performance marine applications.

Reliability and Affordability

  • Proven Reliability: Based on the renowned LS3 V8 engine architecture, our LSV engines, with two fewer cylinders, deliver exceptional reliability. This design is well-tested across various industries under similar heavy-duty conditions.
  • Cost-Effective: Our engines are not only affordable, often costing significantly less than comparable marine engines, but they also offer excellent fuel efficiency. For example, they provide 375 HP with lower fuel consumption, enhancing overall affordability.
