The Mercury V10 cowling is a big canvas — and the Koshi Marine Carbon Fiber Mohawk Kit makes it look like it belongs on a race boat. Five prepreg carbon fiber accent panels per engine, made with Delta-Preg material — the same supplier used by Ferrari and Lamborghini — and autoclave-cured at 140°C / 6 bar for a finish that holds up offshore. Easy installation, precise fit, and a look that's a significant step above the factory chrome trim. Price is per engine.
