Marine engines run hard. Full throttle for hours. Saltwater spray. Constant load. The piston inside that outboard motor takes the worst of it. Outboard engine pistons convert combustion pressure into ...

Look inside any performance engine build—race car, off-road truck, or custom motorcycle. The pistons aren't factory stock. They've been modified. Thinner rings, deeper valve pockets, coated skirts. Th...

Marine engines run under conditions that would kill a car engine. Full throttle for hours. Saltwater spray in the air. Constant load and high RPMs. Outboard engine pistons take the brunt of it. They s...

There's something about Honda motorcycles. They just keep running. Part of that reputation comes from the pistons inside the engine. Motorcycle pistons for Honda are built to handle high RPMs, heat, a...

Marine engines run hard. They sit at high RPMs for hours, deal with saltwater corrosion, and work under constant load. The piston inside that outboard motor takes the worst of it—combustion pressure, ...

You don't see them. But every time an engine fires, a piston moves. Up and down. Thousands of times a minute. Converting combustion into motion. An OEM piston manufacturer makes the pistons that go in...

Marine engines demand components that endure constant operation in harsh conditions. Saltwater exposure. High RPMs. Heavy loads. Long run times. Without reliable pistons, outboard engines lose power a...

Engine enthusiasts seeking more power often start with modest modifications. Improved intake systems. Mild camshaft upgrades. Slightly raised compression ratios. Basic forced induction. Without proper...

Engine tuners and performance enthusiasts seek greater power and reliability. Increased boost. Higher compression. Elevated RPM. Aggressive cam profiles. Without forged internals, modified engines fai...

Marine engines operate under bad conditions. Saltwater corrosion. High RPM loads. Thermal cycling. Continuous operation. Without precision components, outboard motors lose power and reliability. An ou...

Internal combustion engines are everywhere. Cars. Motorcycles. Generators. Marine vessels. Without a precisely machined piston, the engine loses compression, burns oil, or seizes entirely. An OEM pist...

An outboard motor lives a hard life. Saltwater. Humidity. Wide-open throttle for hours. The piston is at the center. It moves up and down thousands of times per minute. It contains the combustion expl...
