I need to figure out what size and year my outboard is.  Here are the only numbers I can find J3274357.  Thanks.
It is a Johnson I believe only thing I have are the symbols on the out side motor case.  I can't find any other numbers.  The numbers I found came of a quarter size symbol near block.  It had a big M on it too followed by the numbers J3274357.

What type of motor is it? Where did you find those numbers?Look on the mounting plate that mounts to transom or on the heads or block it should be stamped in there somewhere.
