Hello!
My question is what year models will interchange with my motor . The mod# is 70973r its a 79 evinrude 70hp 3 cyl. 20" shaft. Ive been trying to figure out the chart and cant get a clear answer. I have read different forums and they have different years one i read was from a 79 to 91 is this correct. How all this happened is i went to drain the oil in my lower unit and it had a crack in it. So i tore it down it down to get it welded. The pinion gear had two bad spots in it , And when i put the shaft out, the pinion bearings went everywhere. Just kinda scared about rebuilding it. It shows shims needed with a special tool for the gear lash. Thinking of just replacing the lower unit. Checked on Ebay they have used ones with no return policy so if i purchase the wrong one im stuck with it.Any help would be greatly appreciated. Im ready to go fishing guys help please lol!
