Howdy ppl! I have a 79 55hp Evinrude model~55975c cc737. I can tinker and repair motors and replace broken parts without much trouble enough to say Im mech incline. How ever.. As for telling if this paticular motor is short or long shaft, Im having trouble figuring it out and not having much luck on finding info on this outboard as too know if its a short or long shaft. I come across a few website saying shortshaft but the majority say long. To me, by looking at it Id say shortshaft. But most searches only have longshaft comments. Haha Hope that all makes sence!! haha damn skeeters driving me nuts..lol cant consintrate on this mobile site.Any help would be greatly appreciated. (about the outboard that is.. However a trick to help reduce the skeeters will surfice at the moment also) haha jk
