We also offer a full line of flat rate troubleshooting and basic engine services.

International DYNO® Marine Dynamometer is a "closed" hydraulic system capable of fully "loading" marine outboard and sterndrive engines for diagnostic and performance tuning and testing. Precise adjustment of "load" and measurement of output are possible throughout the engine's entire RPM range. The DYNO can duplicate most on-the-water situations right in our shop.

Why is Load Testing an Engine so Important?

An engine’s operating characteristics are completely different from no-load (static) running than they are during loaded (dynamic) running. It would make sense that you should do your tuning and troubleshooting on an engine that is comparably loaded to actual on-water conditions. May customer complaints do not show up on an engine operating with no load.
