We also offer expedited shipping and a price match guarantee! So, purchase your OEM 90hp Evinrude outboard parts at Boats.net. We know you will love our easy to use part diagrams and part search. If there is a part you can not find, then call or chat with a member of our customer service parts department. Our agents can help look up your Evinrude 90hp parts using your model number. Your Evinrude outboard model number can usually be found on the nameplate located on the motor or the mounting bracket. The nameplate should contain a model number and a serial number. The model number will identify the year and certain details of that motor. Evinrude outboards from 1980 to the present use a model number that can help determine the year and features of the motor. Evinrude outboards prior to 1980 do not have a consistent model number code. You may want to call us to help you locate a model number on your vintage Evinrude motor. We are here to help!
