Propeller hydrodynamics can be complicated and messy, and sometimes the combination of propeller, vessel shape, gearbox, and engine are less than perfect. Age or lack of maintenance can also compromise performance – frequently causing an overload of the engine and a reduction in RPM. In such cases, it may be possible to relieve some of the problems and shift the operational RPM through a variety of propeller modification techniques, such as re-pitching by blade twist, diameter reduction, or even trailing-edge trimming and grinding. Join Adam Kaplan for this 30-minute webinar explaining the objectives, expectations, techniques, and limitations of propeller modification to achieve performance objectives. Is a new propeller needed to solve a performance problem? Maybe, but not always.
