This thesis has been done at the company MarineDiesel Sweden, which is currently developing a diesel-powered outboard engine. The focus of the thesis is to design and size a trim/tilt-suspension unit, which secures the outboard to the boat. This system allows adjustments to be done to the outboard while driving in order to achieve better performance and a smoother ride.The methods used in this thesis are brainstorming/concept generation, concept selection, load analyses, CAD-modeling and FEM-analyses. One concept was chosen to proceed with, and further development was carried out. This involved design loops due to feedback from the company as well as the results from the FEM-analyses.The final result is a complete suspension unit, modeled and calculated strength wise, in order for it to fulfill the demands set on it. Four major parts were investigated using FEM, and analyzed in order to keep the stresses low as well as eliminating unnecessary material and thereby reducing weight. The material selected is aluminum, which is lightweight and possible to cast in order to produce complex geometries.
