A tool is provided for facilitating angular alignment of a hydrofoil coupled to a mounting block having a flat bottom surface area. The mounting block is pivotally coupled to a cylindrical strut having a longitudinal axis. The tool has a saddle for engaging the cylindrical strut and a plate coupled to the saddle. The plate has an alignment edge that, when positioned by the saddle beneath the flat bottom surface area of the mounting block, forms a desired angle with respect to the longitudinal axis of the cylindrical strut.
