What lower unit fits on a 2001 DF115?

[Suzuki man]

I've read the DF115 was painted white and called a Johnson 115...but I'm trying to find out if the lower unit for a Johnson 115 would fit on a Suzuki. It seems as though the Johnson LU is a lot easier to find than the Suzuki. What LU fits on a 2001 Suzuki?

Thanks in advance...
