I know this is going to be a really stupid question but here goes. I got my model number off my engine and went to searsdirect, put my number in, and every exploded picture shows a single cylinder motor (1 spark plug, 1 piston) but mine is a twin cylinder. Now my question is, am I missing something or could the tag have the wrong numbers on it? I bought the boat & motor in 1989, gave to my Dad a year later, recently got it back from him, and don't remember him getting a new motor for it so I was dumbfounded when my serial number came up as a 1995 motor. My model number is 225.581997 and the serial number is OEO92691. The searsdirect site says there is a safety problem with the flywheel but I couldn't find out anything about that so anybody have any thoughts on that. Thanks!
