What is a Compression Test?

A compression test is used to gauge a boat’s engine health. The test shows how well an engine can compress fuel and air in the engine cylinder. While this test is helpful to determine how well a boat will run in the future, it is not the end-all-be-all for diagnosing a boat engine’s health.

 

What a Compression Test Cannot Do

The primary function of a compression test is to help determine why an engine is not performing well, and not so much what it can do in the future. It’s like using blood pressure as the sole indicator on whether or not you are healthy. It’s helpful – but doesn’t paint a complete picture for someone looking to buy a pre-owned boat in Texas.

 

Compression Test vs. Water Trial

The best way to get an accurate feel for the boat’s performance is to take it out on the water. Pay close attention to the idle, acceleration speed, shifting abilities, and wide open throttle (WOT) for extended periods of time. Check all the bell and whistles. Buxton Marine does not recommend buying a used boat unless you have undergone a full water trial, along with performing a compression test, spark check, and full inspection.
