Re: what year nissan 90hp? pic included
Year is unimportant for servicing a Nissan/Tohatsu OB. Precise model/serial is everything. That may be an NSD90A. If so, it probably dates back to the early 2,000's (say 2001 or 2002). They only used that style logo on the grey colored background for a couple of years. Elvin may be able to nail it closer. If you have a nostalgic curiosity about the exact year, call Nissan Marine at 214-420-6440 with the serial number, and they may be able to tell you.
