I saw a question similar to this posted in another boat forum and now
am wondering about it myself. I have a 1986 Johnson 115hp and have
been looking for a parts motor. From everything I've seen as far as
part numbers go, the two outboards seem identical. Will most of the
parts from a 110hp fit the 115hp, including powerhead and lower unit?

Does anyone know what the difference is between them?

Respectfully,
Syl
