What We Offer

Upgrade Your Boat with Professional Marine Accessory Installation

Accessory installation pricing varies per boat and per accessory. At Sweetwater Performance Center in Oshkosh, Wisconsin, we specialize in marine lighting and audio systems that transform your time on the water. Midwest boaters from Illinois, Minnesota, Michigan, and Iowa make the trip to our waterfront facility for upgrades they can't find closer to home — from underglow LED systems and cockpit speakers to full custom electronics builds.

Our Ship Store is fully stocked with accessories from the top marine brands, including LED lighting, audio equipment, fish finders, GPS chartplotters, and general boating gear, all at competitive prices. Whether you know exactly what you want or need guidance, our team helps you find the right setup for your boat and your budget.

From simple plug-and-play upgrades to full custom wiring installations, no job is too big or too small. We work on all major boat brands and engine types, and every installation is performed by factory-trained, certified technicians at our full-service Oshkosh marina. If you're serious about your boat, we're serious about getting it right.
