I looking for the capacity information on a riviera pontoon boat model FD2000?

There should be a mfg. ID plate mounter on the steering console that will have this info. Also the USCG test pontoon boats and establish the capacity and HP ratings. I couldn't find your model but something close. 1500 LBS and 35HP. I'm unsure of engine weight and fuel count in Cap. but I thing it does. More info might help, like what engine you have or fuel cap. etc, or a photo>>>
