I have a outboard 1973-91 repair manual that includes all 60-235 hp, 3-cylinder, v4 and v6, 2 stroke models. Ordered it form iboats.com phone-1-800-931-1123. Helped me on a job i had to do to my 120. It would probably be best that you get your own book but you are more than welcome to take a look at mine. Probably be cheaper to get your own depending on how far you live from me
