Look on engine block for a alum plug with serial number, other than that no way of knowing.

thanks, for the info. The plug number is 374781, that tell you something?

No, if that is the serial number then may be early 90's

I need parts for the lower unit, Do you think with that reference is close enough to order parts?
I took the lower unit apart and need to replace all the bearing and seals plus the bottom part of pump housing that fits inside the unit housing and the pump ofcourse, ah! there is a plastic tube underneath the pump need that too..
I think I can get my parts thru this page...is that correct?
