From their painstaking design to their meticulous construction, Yamaha outboards are manufactured to provide you with years of enjoyment. However, they live in one of the harshest environments imaginable. High load, high-RPM operation, extreme temperatures and humidity, saltwater, sun, even long periods of non-use can all exact a heavy toll. And it’s not just Yamaha outboards. All outboards face these same challenges. Regular maintenance is important in helping your outboard meet the demands of these challenging environments, and only you can make sure it happens.
