My 1988 110 johnson was recently stole from boat storage.Now i`m needing to replace it and found a 1985 140 johnson they are both 20 inch shafts.What i`m needing to know is if the wiring harness would just be a plug and go type deal or would there be bunches of wire changes with different alarms and such.My friend says they`re both v-4`s so just hook `em up and go. I would rather check first. The 140 has 125 pounds comp.in all cyl. and the tag on my boat says i can go up to a 140. thanks for any help and replies. allen
