FWIW, for any who may follow this thread later.
I found a couple places online selling the nissan (2007) 6hp 4 stroke with the 20" shaft for $1275.
It looks like the vertical pull option is still available one place I called quoted me $89.99 for it, and I can get the 7" pitch prop for $59.99. The charging option looks like $145.
It seems as though the Mercury price is higher for some reason...
The guy I was talking to said he paid around $1600 for his, and they seem to retail for around $1800.... can not figure out for the life of me why.
