Thinking about picking up a used Evinrude 25 commercial for a couple hundred bucks, noticed that in 1985 the commercial model had the old split style lower unit case,where as the residential model had the newer stlye lower unit. From the BPR parts site it looks as though it might be possible to interchange these as the midsections look pretty much the same, I realize the area of concerns would be drive shft, exhust(thru prop vs external),shift linkage and bolt up pattern . My thought is that the availability of parts or replacement, if needed, would be greater with the newer style LU. If any has experiance with this or input about it, it would be appreiated. Also I can't seem to find a great deal of info on the difference between Commercial motors and Residential any input there is also welcome.
Thanks
