Secret No. 4: Poor performance does not automatically mean you need a tuneup or a new prop.
There are many overlooked contributors to poor performance. Look for simple answers first, like water in the bilge. At nearly 8.5 pounds per gallon, undiscovered water can seriously sap a boat’s ability to get onto plane or reach top speed. Bottom growth is also a notorious culprit. While the incorrect prop can also seriously hinder a boat’s performance, be careful; our experts have firsthand knowledge of shops incorrectly diagnosing a prop change when the boat had only grown heavier from the reasons above, or from an accumulation of equipment stored on board. Multiple tuneups are often thrown at engines that are simply tired and in need of a reconditioning.
