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...

An engine is only as good as its parts. The piston is one of the very critical. It moves up and down thousands of times per minute. It takes the heat of combustion. It transfers power to the crankshaf...

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

Off-the-shelf pistons work fine for stock engines. Rebuild a factory engine, and standard sizes fit. But modify the engine. Add boost. Raise compression. Change the bore or stroke. Standard pistons no...

Marine engines work in conditions that constantly shift between load changes, moisture exposure, and long periods of idle operation. Inside these engines, Outboard Motor Pistons play a central mechani...
