1981 Johnson 70 hp, Model #70ELCIM
I picked this motor up this spring to replace a 1975 we've repaired a few times...same 14' boat glass boat.
The carbs were cleaned (twice to be sure). It starts easy, idles smooth, has great mid-range power (two tubes), and is very smooth on the top end...
Yes, it's bogging.
We also tried a smaller prop hoping to get it through the bog, but no luck.
I hope your kids are more patient than mine. This was to be a step up from the 1975 which had a cracked piston, bearings in small pieces, etc....and still had more power than this one.
