My boat has a New Double AXLE trailer with Disk brake. which i have no clue how to use.. i don't see any wiring beside the trailer lights. I assume the disk brake on the trailer operate by pressure. when i hit my SUV brake the trailer brake activate.

Iam really scare to pull big boat. i only fell comfortable when i use my friends lifted truck to tow it. but now i have a SUV of my own i want to be sure if my SUV will be more than enough to tow my boat

My SUV has a 5.7 V8 350 Engine
the SUV it self weight about 3,000 pounds.

sorry for the English. please advice me

No, you need to get a trailer brake controller. It's a lil box that usually gets mounted up under you dash somewhere that sends power to the trailer's braking system when you step on the pedal.

I wish!! I bet it's closer to 5700 ...

Trailers with brakes typically have two kinds.

Electric as retorq mentioned, but you mentioned that you didn't see the extra wire.. ie 4-pin flat plug no e-brakes. If your plug is 7-pin round, then odds are you have electric brakes and will require the trailer brake controller.

Or

Hydrolic, as you think that you may have. If it's hydrolic, then look for a big cylinder near the ball hitch mount. You should see extra hardware that other trailers don't have. This type of brakes has a safety wire that when trailering should be attached to the same place as your safety chains on the truck hitch.


As for your truck being able to handle the 5000+ lbs. Yup no worries.
I towed my tractor with calcium filled tires over 700+kms to Ottawa for repair with my wife's Jimmy! With trailer and tractor wer'e talking over 6500lbs. That trailer also had hydrolic brakes, and when going down hill, with your foot of the gas, just idling, you can feel the trailer push the truck, then the trailer brakes would kick in as the pressure went up, then the trailer would brake while the truck was coasting. It would produce a bucking action that can be un-nerving at first, but then you get used to it.

That little 4.3l 190hp truck pulled that tractor at speeds up to 110kph(60+mph), of coarse the onboard trip computer told me that mpg never went above 8.5 or so, and dropped down to 4 when going up a hill. So if a v6 can handle it, then so can your truck!


BTW, while towing never drive in OD(4), always drive in 3, it's easier for the tranny. At least that's what I was told and what I did.

i have a 21' bay boat that i don't have any problem pulling. my buddy's 1500HD does a better job, but my yukon does good. the rear springs aren't really the stiffest, so it may bump the stops or the overloads, but it'll pull it fine. may wanna look into some helper springs or some heavier springs/helper bags if you plan on pulling it often.

I will sure install a helper bag before even trying to pull. i have a Serge Brake for my Trailer. I have a OIL reservoir next to the Hitch. so i assume when apply pressure on the brake it apply pressure on the Hitch and slow down the Trailer.. PERFECT for me.. i don't have to buy any other parts..

maybe i will find a Truck Weight Scale around my area and see how heavy is my boat and the trailer together so i could get a better understanding

You should be fine as far towing the boat. My truck tows our 22 foot Cobalt boat with a 454 with no problems. Of course that's just to lake michigan like 10 minutes away. As far as I know, most boat trailers have surge brakes, I know ours does. When you get into larger trailers like cigarette boats and campers those have the electric brakes requiring a brake controller.

I'll bet that according to the factory owners manual, 7,500 pounds is too high. A lot also depends on where you live (what altitude) and is it flat land or very hilly.

I put a 5,800 pound trailer behind an F150 which has 3.73 gears, tow package, etc and is rated at pulling 8,900 pounds. At 3800 feet above sea level and on a road with an actual 11 degree grade, the truck could not get above 50mph.
