Yep. Boat & truck are described below. My truck has the 4.6L. The boat & trailer with full fuel, full water, anchors, toys, etc. is exactly 6,500#. I can't tow in overdrive and would advise you not to do so either. However, my truck does much better than I expected pulling this load. It struggles if I get into really serious hills/small mountains (i.e., Ozarks) but short of that, it does well. I have the tow package with 3.55 LS rear end, and this load tows at 65mph at 3,000rpm. Prior to this boat I'd never towed anything with this truck, and was accustomed to the engine never running over about 2,300rpm in OD, so it was very nerve racking to hear the engine "scream" at 3,000rpm. However, in towing it for two years now, and talking to a lot of Ford people, I've come to realize that the 4.6L and 5.4L engines will run all day long at 3,000rpm's (and even a little more) and be quite happy to do it. My engine temps don't even go up any while doing that in August.
My next truck will have the 5.4L or equivalent at a minimum, and I haven't ruled out a 3/4 ton Powerstroke or equivalent. In other words, I'd very much like to have more power, especially low end grunt, but this truck is way more than adequate under most conditions. The rule of thumb is to adhere to the "2/3 rule" - where the truck will suffer the least from towing if you keep the towed load at 2/3 or less of its rated capacity. As it is, I'm 1,000# under capacity - a little closer to the limit than I'd like.
Your load will be a few hundred pounds lighter than mine and you most likely have the 5.4L engine. Do you have the tow package, and do you know what your rear end ratio is?
