Hey Guys/Gals,

I currently have a 2015 F-150 supercrew 145" 4x4 with 3.5EB and 3.55 axles. I have a 2007 Sea ray 220 weighing in with trailer and everything right at 6K pounds. I leased this truck for my own personal reasons and I'm glad I did because I'd like to do a few different things on my new truck that i actually plan on buying. With my current boat I'd like to step in to the same set up in my truck but with a 2.7EB motor in my next truck. So here are my choices for my next truck from my most desirable to least. I'm trying to get a little gas mileage back if possible even when I'm not towing the boat.

1- 2.7EB with 3.55 axle and 7600LB capacity
2. 2.7EB with 3.73 axle and 8000LB capacity
3. 3.5EB with 3.31 axle and 10,700LB capacity
4. back to the 3.5EB with 3.55 axle and 12,700LB capacity

If I go with the 2.7EB with 3.55's is that going to be enough to safely drag around the boat, people and stuff? should I just step back in to a 3.5EB with 3.31's and have a little extra safety margin with the 10,700 capacity? All I'm looking to do is safely tow the boat. I won't be towing anything bigger or heavier than that. Thanks for your help and wisdom in advance!!!

Personally I wouldn’t get a F150 to tow over 5000 pounds. Maybe if it was once a year, but not regularly. I made that mistake before. 0-5k F150, 5k-10k f250, 10k-15k f350, 15k+ f450

If you want to tow comfortable that is.

Following. I have the same truck setup and a boat weighing about the same - ‘04 Crownline 230BR. I love the way the 3.5EB tows it. I’m always looking for boat towing threads, as most towing discussions involve campers. I get 15-16 MPG around town without towing. It plummets to around 9-10 MPG when towing the boat.

The limiter as to the max weight of a trailer you can tow safely tow is payload capacity (GVWR minus weight of the truck). It's not the tow rating. The F-150 with 2.7L EcoBoost drivetrain have reduced payload capacity, so if you buy a 2.7L be certain it has the 2.7L Payload package on the window sticker. That pkg includes the 3.73 e-locker axle, and is not available with Lariat or fancier trim, the Max Tow pkg or High School Harry's combo of regular cab and short bed.


You'll be much better off with the 3.5L EcoBoost engine and the max tow pkg. That pkg is available with almost any trim level from XL to Platinum, and includes 3.55 e-locker axle, 35-gallon gas tank, and the integrated trailer brake controller (ITBC), plus a few other goodies. And my 3.5L EcoBoost F-150 is a towing monster. Your 6k trailer will be no problem for it at all, even if you decide to drag it up a mountain.

I have a 2.7 with the 3.73 e-locker. I've put over 6k of just boat towing miles on it. The truck has a total of 40k miles. The boat I tow is almost exactly the same size and
weight as what you have. I average 13-15 mpg towing, depending on city/highway. It has plenty of power and has not given me a single problem. I'm more than happy with my choice in the 2.7 ecoboost.

yeah I'm thinking that if I do go for the 2.7EB I'm going to need to get the 3.73 rear end. Seems like the best combo for towing the boat and fuel economy.

That setup has worked perfectly for me. Right now my mpg reading is showing 23.9. That represents my daily drive to work which is 35 miles one way, at an average speed of about 65mph. Part of that is just driving conservatively and staying out of the turbos when possible. Now if I'm on the freeway doing 80mph, then I'll only get about 21ish.

I think that combination would be fine. My Chaparral 220 had an all-up weight of just under 6K and I was pilling it with the '05 in my sig. with no problems, power wise. The tongue weight on your boat is going to be something under 400 lb. so payload will be a non-issue. An HDPP would be nice if you happen to stumble upon one, but far from a necessity.
