• The Thunderbolt® V Hi-Energy Ignition continually adjusts the timing for optimum midrange performance and fuel economy.
• Technologically advanced roller cam design provides a lower friction coefficient, improves low-end torque, offers higher levels of performance, and aids fuel economy.
• Thunderbolt V Hi-Energy Ignition System allows for improved responsiveness, idle stability, and overall reliability by providing digital electronic spark advance, idle speed control, acceleration advance mode, and mean best timing.
• Dry-joint exhaust system eliminates a potential leak path, reduces a build-up of condensation and decreases the threat of water ingestion for longer engine life.
• High-flow cylinder heads with enlarged intake ports dramatically improve air flow throughout the engine, providing up to 10 - 15 percent greater horsepower output for the same engine displacement.
• Standard audio alarm system warns of low oil pressure, high water temperature, and excessive transmission temperature, reducing chances of engine or transmission damage.
• Top-mounted starter is mounted up high away from bilge water for dependable starting and extended starter life.
• One-piece serpentine belt means easier servicing, less maintenance, unsurpassed belt life, and requires fewer horsepower to drive the engine accessories.
• To make winterization easier, color-coded drain plugs are located on the engine block, exhaust manifolds and the circulating pump hose. The blue drain plugs are hand-removable and require no tools.
• A 65-amp/917-watt alternator system provides plenty of power to keep batteries charged and to run electronic accessories. The alternator is located high on the engine to eliminate water contamination.
• A rev limiter is standard along with an electronic idle control, which aids in low-speed operation and eliminates shifting stalls.
• Water-separating fuel filter ensures dependable starts and performance by removing water and solid particles from fuel before they reach the fuel system.
