This fellow I know walks to my for sale outboard rack and ask how much for the 25 commercial ? I said I did'nt know the 25 was a commercial , I looked at the mod# sure nuff it said e25rlccca Well the conversation turned to other outboards but again by just walking up to the outboard and from 10-15 ft away he spotted the motor straight off the bat as a 25 commercial, So do these commercial 25 hp motors have a very obvious "something" that jumps out to you folks in the know? if so could I get the run down on what should jump out at me. thanks school me please!
