Balanced Engine The 115 HP has twin counter-rotating balancers that cancel out internal engine vibrations, providing smooth operation throughout the entire RPM range. Top Centrifugal Clutch This feature maintains a smooth idle, until the throttle is advanced above idle speed. Then it automatically engages the prop. It's like having a neutral position. Top Dual Stage Induction Most 4-strokes use long manifolds to deliver air into the cylinder head. Honda's variable intake system utilizes a plenum chamber with twin butterfly valves to control the volume of air taken into the combustion chambers. The result is a simple, compact design that improves overall operation. Top Engine Command System The ECM receives constant input from 18 different sensors, delivering instant starts, smooth operation, strong performance, and excellent fuel efficiency. Top Largest Capacity Alternator 15/20 HP At 12 amps, the alternator on the 15/20 HP will keep your battery charged better than the alternator on any comparable engine on the market. Top Largest Displacement 15/20 HP With a displacement of 21.4 cubic inches, this is the power king in its class. Top Largest Displacement 115 HP At 137 cubic inches, the 115 HP has the largest displacement in their horsepower range. Along with their long-stroke design, that makes them the most powerful engines in their class. Top Large Displacement 200/225 HP V6 60° V6 3.5L (212 cubic inches) A powerful, compact 24 valve SOHC design. Lacking the bulk and weight of long intake runners and multi-camshafts, the narrowV6 design offers top performance and durability, based on Honda automotive engineering excellence. Top Lightest 4-Stroke 15/20 HP At 101 pounds, it combines the smooth-running efficiency of a 4-stroke design with the lightest weight of any engine in its class. Top Lightest 4-Stroke 50 HP The lightest 50 HP 4-stroke available on the market. Perfect for pontoon, aluminum fishing boats, and the increasing bay boat market. Top Non-Linear Mounting System Patented non-linear rubber mounts provide smoother operation at all engine speeds. Top Offset Crankshaft Design This locates the power head directly over the transom pivot point, reducing vibrations and increasing the performance and handling characteristics of the hull. Top Exhaust Relief Reverse exhaust relief creates more power in reverse by minimizing cavitation around the propeller blades. Top Torsion Dampener Sometimes called a flywheel, it is located near the base of the power head. This design lowers the center of gravity for improved handling and hull maneuverability. Top Tuned Dual Exhaust The competition's exhaust track goes through the middle of the oil pan, heating the oil. Honda's dual exhaust headers wrap around the outside of the oil pan, reducing heat build-up and increasing engine efficiency and performance. Top 90 AMP Alternator A proven on-demand, belt-driven alternator that reduces heat build-up and provides superior battery charging capability. Top Dual Overhead CAM (DOHC) A powerful, compact 24-valve DOHC design creates more valve lift to pull in more air for increased horsepower. Low-maintenance design allows easy adjustment of the rocker arms. No multiple shims or trial-and-error adjusting needed. Top Lean Burn Feedback Control Utilizes a Linear Air-Fuel Sensor, along with the Engine Command Module, to automatically adjust the air-fuel mix according to speed and load - maximizing power throughout the RPM range and providing twenty percent greater fuel economy in the cruise mode from 2000 to 4500 RPM. Top 3-Way Cooling System Three separate cooling systems keep the cylinder head cooler for more long-term durability. Top VTEC Variable Valve Timing and Lift Electronic Control system achieves the best of both worlds by utilizing mild cam lobes to operate the intake valves at low RPM-then, at 4500 RPM, engaging a "high output" cam lobe for high RPM operation.
