Abstract
A breakaway skeg for the lower portion of a marine propulsion unit is disclosed. The skeg is designed such that the attachment features will fail under certain load or impacts, thereby preventing damage to the lower portion of the marine propulsion unit. The breakaway skeg is attached via shear tabs that include a relief that accounts for at least a part of the volume of the base portion of the shear tab. The shear tabs are designed to fail under certain circumstances before other components of the marine propulsion.
