I have a 1970 evinrude 115 hp I just recently purchased for my dads stratos the motor runs great but we didn't check to see if it was going in the correct gear due to the water pump being out so we took off the lower unit and changed it but the electric shift is in the lower unit also and we had to remove it and I'm 90% sure we put it back correctly cause my dad was the one remembering how it came apart so we got it back together and it was pumping water but not changing gears so I checked the forum and put my green and blue wires to 12v to change the gear but all it did was burn up my jumper wire so now I am lost can y'all please help me fix this I would appreciate it
