Hi Kadin,
If you say Manaus, you're talking about the Amazon river. You can take some boat trips on the Amazon but I've not heard of boat rides going back and forth to Colombia or Peru. You're probably not considering the time it would take to travel such a distance by boat.
I had a river boat ride from Trinidad in the Amazon Basin of Bolivia to Guayaramirin, a city bordering Brazil. It took me 1 week. You can
read about the river boat trip here.
Best wishes,
Mark
