Re: What year model would a nissan ns40c with ser# 361a-1-84526???
Year is 100% unimportant for servicing a Tohatsu/Nissan outboard. Likewise, if buying or selling a motor of that age, condition is everything, and year means nothing. BTW, your serial number is 84526. The 40C was made from the early 90's to the mod 2000's. If you have a nostalgic curiosity about when you motor was made, you could ask Nissan Marine at
