💡 Parts Desk Insight
On high-horsepower offshore engines like the F300/F350, a failing impeller can still move water at idle but struggle at higher speeds—leading to overheating when running hard.
Replacing it on schedule helps protect your engine and keeps performance consistent when you need it most 👍
