Valve Adjustment

Precision Valve Service for Racing Engines

Sweetwater Performance Center offers complete valve lash service on all Mercury racing engines — one of the most specialized services available at our Oshkosh, Wisconsin facility. Performance boaters from across the Midwest seek us out specifically for this work because finding a certified technician with genuine Mercury racing engine experience is not easy. When valve clearance drifts out of spec, your engine becomes noisy, loses power, and suffers accelerated internal wear. We fix it right.

Our certified technicians measure and adjust each valve to the manufacturer's specified tolerances, ensuring your Mercury racing engine is running exactly as designed. We also perform valve spring replacement when springs are worn, fatigued, or have reached their recommended service interval. All work is documented to protect your service record and engine warranty.

If you are hearing a ticking or tapping noise from your engine, or if your engine has reached its recommended valve service interval, don't put it off. Performance engines across the Midwest come to Sweetwater specifically because we have the expertise and the certification to handle this work properly. A properly adjusted valvetrain keeps your high-performance engine making power when it matters most.
