Abstract: A system for measuring angular misalignment between marine propulsion devices. The system includes first and second members with mounting ends and distal ends. Attachment features are positioned at the mounting ends to attach the members to first and second propulsion shafts of the marine propulsion devices. Emitters configured to emit light are coupled to the first and second members. When the first and second member are attached to the propulsion shafts, a first emitter emits the light towards a target on the second member and a second emitter emits the light towards a target on the first member. The angular misalignment between the propulsion shafts is measurable based on a first offset between the target and where the light from the first emitter shines on the second member, and based on a second offset between the target and where the light from the second emitter shines on the first member.
