Nobody can give you a good answer based on a description. Even with a boat-load of pictures, it would just be a complete guess. Condition is so important to the price of a boat more than a couple of years old that any useful guess would require a thorough examination of the boat.
In addition, the market price is going to vary drastically from one location to another, so any guess would have to take that into consideration, also.
In the end, the bottom line is that if you want to sell it quickly you have to price it lower. The fact that it has not sold in the amount of time that you WANTED to sell it in, tells you that you are asking too much.
Offer it for $1 and I'd bet you could sell it tomorrow. Offer it for $1 million and you will probably never sell it. Somewhere in between there is a price that will get it sold in the next few weeks, or months. You just need to figure out what the right price is.
