First post. I have a 1968 40 hp selectric shift evinrude. I have the lower unit apart replacing top oil seal. The motor was acting up at the end of the summer and would not shift from the lowest speed,just rev out. I had water and oil mixing so took apart lower leg the top seal on the drive shaft rod below the water pump impeller was shot. Ordered parts put everything back did an air test no leaks. Was careful with shift wires not to pinch on reassemble and I decided to check the ohmns on the lower leg. I have a reading of 2.6 ohmns. The manual states I should have a reading of 5 to 8 ohmns. Does this mean the guts inside the leg are shot? I know these can be expensive to fix and a pain. Do you think the low ohmn reading indicates why the no shifting from low gear. Or would it be worth trying this when the ice thaws and see what happens ? Any replies would much be appreciated I have learned so much from this site just reading over the last few months.Thanks to all who post great knowledge out there.
