Yes I have a 1987 Evenrude that the lower unit is shot I have a friend with a 1977 lower unit for a 140 evenrude I would like ti know if it will work..........Trying to save a little money. Going to buy a new boat in a few month but still have a few tournaments to fish before I get it.

I don't think it will work but get both L/U's and compare them.

I believe that lower unit will only work up until a 1985 Model. After that, it's a 1986-1991 that will interchange with the 1987 Model .

Look at the shift rod top. If it has a threaded "barrel" on the 77, it will not exchange as it is a Hydro-mechanical shifted lower.I believe that 78 was the "break-year" for hydro and mech'. 78-early 91 are interchangeable the 86 break was when they switched to a wider cavitation plate, a mostly cosmetic change. In late 91 they switched to a 2 piece driveshaft setup that can be used on earlier units with the proper upper driveshaft. In 93 a change to the crankshafts (sleeved lower seal wear area)goes hand in hand with a change to the driveshaft (shortened by about 3/8")because the crank splines arent as deep. If the 77 is hydro (has threaded barrel on shift rod top) and has a 6 bolt cover where the shift rod comes out of the lower, it is hard to find, and valuable to someone who needs it. (just the fwd gear from these units last sold for over 350.00new!!)
