NOTE: This propeller selector, and the information it provides, is to be used only as a general reference guide. Results will differ, based on various factors including, but not limited to, application, conditions, and load. More accurate information for a particular boat/application may often be obtained from the boat manufacturer. The most effective method to select the proper propeller for a particular boat and engine application (based on usage and needs) is to test various propellers directly on that boat. Part numbers are provided for reference only, and may change at any time. [links]
