Hi everyone. Surely someone can figure this out! I'm stumpped!<br /> I have an old evinrude o/b that I think is a 4-5 h.p. It has the lower unit that is hinged and folds up to the side. However, The only I.D. I can find is the freeze plug (?) on the top of the block. The #'s are 3633E and under that E01205. Does anyone have any info - year, h.p. on this little motor. It was completely rebuilt last year. Thanks in advance! Dave
