There are many websites you can go on to find out the value of different outboard motors. One of these sites is NADA Guides. These all give guide prices on all different makes, models, and age of an outboard motor. Another place you might want to check out is eBay, especially if it is a second hand one you are looking for the value of.
If you go into advanced settings on the search bar on eBay you can actually view recently finished auctions which will give you a good idea of how much certain outboard motors are selling for at the moment, although this is not the most accurate value as the serious outboard buyers or sellers will not necessarily turn to eBay to sell their motors.
However, if it is an older outboard motor you are seeking the value of there are books you can buy that indicate the guide price for older motors. One of these books is called the Old Outboard Book and lists many of the older models with the up to date prices. There are still quite a few collectors out there who are into the older outboard motors so if you want to sell one then it may be worth looking out for any adverts in the wanted section from collectors who are after older models, because if you have one they are missing from their collection then they may well be willing to pay a bit more to get their hands on it.
