Overall Assessment

Customers praise the product for its superior quality and affordability, particularly noting that the pistons are a preferred choice over marine dealers for SeaRay Mercruisers. They recommend the pistons for durability, even under intense heat and pressure. A standout feature is the dished design, which maintains a reasonable compression ratio in 383 boat motors.

I've used Keith Black pistons before and have been happy with them. They're a quality part at a reasonable price. I needed a dished piston to keep the CR reasonable for my 383 boat motor. I've never encountered a anything but an extreme performance build where a hypereutectic piston wouldn't stand up to the heat and pressure!
