Frequently Asked Questions

FAQ Icon

A Dynamometer is a device that provides a measurable load (force) on an engine. This International Dyno service of Marine Dynamometers provides a load for marine outboards and I/O's to closely simulate actual on-the-water operation. Dyno load measurements can be used to evaluate an engine's full throttle power and acceleration.

An engine's operating characteristics are completely different during no-load (static) running than they are during loaded (dynamic) running. It would make sense that your 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.

It takes 5-15 minutes to connect the Dyno and run an engine test. Compare this to the time it takes to water test an engine. Also consider the fact that you can Dyno-test day or night, regardless of weather, and in your shop where your tolls and parts are always within reach. Your liability exposure for worker's comp and the customer's property is drastically reduced. To verify your solution to the engine problem, you would need to re-water test. The Dyno would only take 5-10 minutes.

Test tanks are fine for the lower horsepower engines and a limited among of applications. Few engines can be run at full throttle in a tank with a test prop without aeration and prop cavitation. This will cause engines surging. A full line dealer would need a wall full of test props. Also test tanks are not portable.

Dyno testing will not harm an engine. All you are doing is duplicating normal operating conditions, in your shop.
