Below you will find a number of tests with varying configurations of engine and boat. Maybe is not your boat or motor represented. We are however continuing to update the registry and hope to add new tests that come in via our fair offer for test driver assignments.
Buster XL / Yamaha F115 hp
Cruising speed increases with 5 knots in comparison with Yamaha original steel propeller.
In this test, the pitch is the same even though we are changing from a 3-blade to a 4- blade propeller . The engine has the capacity and strength to cope with it and it results in higher speed over the entire varvtalsregisret . The difference is about 2 knots top speed , the original propeller advantage.
