Comprehensive Diagnostics for Every Engine Type

Modern marine engines rely on advanced technology — and proper diagnostics require precision. That’s why we use digital engine diagnostic tools to accurately identify problems before they become costly failures. We read fault codes, test compression, inspect fuel and ignition systems, and verify cooling and electrical performance to find the exact cause of any issue.

Once we know what’s wrong, we provide a clear explanation of our findings and walk you through your repair options. Our goal is to make the process straightforward and transparent, so you always know what’s being done and why.
