Hi folks,
I have recently bought what I thought was a 1990 model 90hp 2 stroke Yamaha but the more I look into it the more I think it's an earlier model (!!) I would like to adjust my timing but the manual I found online is for the newer 90hp motors and mine looks like it has an earlier system for the timing retard/advance. The attached image (if this works) shows the difference. My motor is like the one in the photo vs the one in the manual which shows an arm to the left of the throttle lever which points to marks on some plastic case. Looks like my timing adjust arm is at the top of the throttle control lever. Does anyone have advice, instructions or a link to an online manual for this model of 90hp? And anyone know what years these engines had this setup. The image I have here in the photo is a 1986 model!
