Just bought a new boat and it feels like a fat man on a moped. It just has no towing power at all. Honestly feels like I am trying to tow a house and its only a 1200 load. I have dual exhaust and a 4.6L motor. Would going back to a single tube exhaust help at all? Is there any other suggestions? thanks for any help!!

 

How much are you trying to pull?
And what expectation do you have?
I pull nearly 11,000 gross combined weight with an 02 Screw stock.
The dual exhaust may have lost some low end torque if the stock muffler has been changed.

 

The boat only weighs 1200 pounds and I have a glass pack that Y's off after and splits to dual exhaust with echo tips. Would going back to a stock exhaust with a single pipe give me back some towing power/torque?

 

Does the trailer have brakes? They may be dragging. The spindle bolt holding in the bearings may be too tight and causing drag. Do you have oversize tires? New airfilter, fuel filter, do all the simple stuff first. Your cat may be glogging up but the dual exhaust is only a minor loss.

 

Something's gotta be wrong...I pull a 16' boat all the time, and I can barely tell it's back there, unless I'm on a hill. What gears do you have? And if anything, the glasspack is what's killing you.

 

I have the 3.55 gears and the trailer does not have a break system. Its not the trailer, I hauled it behind my dads truck and it was fine. So should I change out the exhaust?

 

It probably isn't your exhaust.

What rear axle do you have?

Something doesn't sound right. I pull a 14' utility trailer with a quad and mower and have no problem. Try changing the air filter and getting a tuner, maybe changing gears. I can't think the exhaust would hurt you that bad. Hope this helps.

 

I have the tuner, aftermarket air intake, and the 3.55 gears w/ the dual exhaust. Any more suggestions??

 

It would be hard to believe the truck is even running very well by it'self, at this point.
A 1200 lb load is not much.
Use the stock factory tune and give it a couple weeks to settle in and see if there is a difference.
Are any codes present?
At this popint, there is nothing to go on until you find something.

 

Everyone here is missing the point. Weight is almost never an issue when towing a trailer at highway speeds. The important thing that influences towing is the trailer's surface area. If you have a very large boat (1,200 lbs or not) it WILL be hard to pull. Plain and simple. Get us a picture of your boat. That will help a lot. Or just tell us the model and company and we can google it.

I pull stuff every day. A peanut trailer, for example, doesn't weigh but 5-6,000 lbs empty, but an f-150 WON'T pull it much over 60-62 mph. It's because it has so much wind resistance.

 

chester, I hate to mess up your one man band, but any time you want come and have a ride in my SCREW pulling a loaded 22' enclosed with a flat front at 85 mph , you welcome.
No tune, no exhaust, no nothing but advanced transmision cooling.
Keep telling me I'm missing the point.

 

If you can get it up to 85, then it's not near as hard to pull as a peanut wagon. It has a flat front, flat rear door, and an open top!! I doubt very seriously that a PSD would pull a peanut wagon 80mph.

I've pulled a lot of stuff with my truck. I am not an expert in engine electrical systems, (that's why I don't post much about them) but when it comes to towing, I know my stuff. I've pulled everything from excavators, to semi-trucks, to harrows, with my truck. Bring your SCREW to my house, and I'll let you hook up to a peanut wagon or two and try I'll bet $100 you can't get up to 70 with the petal to the floor in 2nd gear. Your truck probably won't pull it much over 60 in 3rd.

You can even give your advanced transmission a challenge with 4 of them:

 

Chester, you can't get past 60 with one of them on or four of them on? And since this thread has gotten nicely derailed, bonefish, what size tubing do you have?

 

I've pulled a lot of trailers, but I never tried to pull a four wheel trailer with front steering wheels over 30 or 40mph (the old anhydrous ammonia tank would sway from side to side). But back to the thread, with 3:55 for a rear end and a 4.6L up front it will seem doggy, you should have at least 3:73 depending on the size of your tires.
