I've only been able to take my boat out once since getting the outboard. I had way to much weight in the rear of the boat and couldn't go more than half throttle. I moved the batteries and anchor to the front of the boat and removed some other weight. When I take it out again what speed should I expect with a Mercury 9.9hp Bigfoot and a 14' Deep V? Total weight of everything including me is around 900 lbs. I'd like to have an idea before I go out again so I know whether or not everything is functioning as it should or if I need to change some more stuff around.
