this is my first post so be nice, , i have recently swapped my engines on my boat
previous engine 1987 johnson 70hp to a 1980 evinrude 100hp v4,
main reason being i wanted more power and the 1980 i picked up real cheap.
my first real problem is, i have attached the gear shift and throttle cables from the original control box on to the 100hp however i cannot seem to get both forward and reverse gears, i have adjusted the thumb wheel back and forward a million times and can only seem to get forward and neutral OR reverse and neutral not both. the control box is OMC and from what i have read so far the cables and controls are the same outfit from 1979 all the way thru to 1995, i still have the 70hp sitting around so i looked at the gear lever movement on this. it seems to be about 2 inches either way to engage the gear but on the 100hp it seems to be 3 inches either way, and my cable seems to reflect this (2 inches each way).
have i got the wrong cables or is there adjustment for the amount of movement inside the control box that i have missed, or better yet have i missed something completely.
any replies or ideas will help and i am pretty mechanical minded so dont mind a challenge
