These third-party bulletins are provided by Volvo Penta, BoatTest.com, and Mercury Marine. Many engine/model combinations are available, so these reports can be printed and used to compare the performance of our Z-plane hull to other manufacturers.

For further comparison information and over 4000 independent boat tests, take advantage of the Performance Comparison Tool available at iBoatInfo.com. The iBoatInfo database contains both performance and fuel efficiency test data from many third-party sources, including engine manufacturers and leading boating publications.

Results on individual boats may vary depending on many factors, including weather and the condition of the propeller, lower unit, and boat bottom.
