Well...we took the bat to the river and had a good day...upon going to get the trailer my wife noticed one of the long bunks was almost completely ready to fall off!! Two of the screws were missing and the front one was barely in the wood. You could grrab the bung and move it to the side.

Imagine trying to put the boat on the trailer to have it move over! I called the dealer about getting it repaired and they quoted me $580-$620 dollars to replace them all!!!!!!:mad:

You guys should check the screws on your trailers for them getting loose. The warranty on the trailer is only one year so I basically am on my own.

Re: Boat Trailer Repair

i was looking at mine the other day and i noticed it needed new bunks to, same way yours does the screws are falling out, but mine is 15 years old as well

how do you guys do it, i was thinking one day when i go out to launch with what i need ready to go, launch it and tie it off for an hour while i fix it or is there a better way at home? plus side is i have enough pressure treated 2x6 from when i built my deck laying around so all i need is carpet and screws

Re: Boat Trailer Repair

I have been watching some YouTube videos on it...so i think I will try to do it myself. I am also going to try and add some plastic sliders to help it get on and off the trailer easier!

I feel your pain bought my Tahoe used and had to replace all of mine with in a couple of months. From what I can figure is the boat was stored outside with a cover and when it rained water just rolled down the side of the hull and into the carpet on the bunks holding moisture over time and just rotting them with in a couple of years. I keep it stored indoors now and mine are rock solid even after a few years. (also wonder if they use pressure treated lumber or not when making these since they fail so quickly)

I will throw my 2 cents in and tell you how I did mine. The bunks on my trailer came from the factory just secured with a lag bolt from underneath the bunk, screwed through a hole in the arm off the frame up into the wood and about half had already worked there way out and were missing when I realized I had a problem.

Hint #1 dont buy bunk carpet precut its way OVERPRICED ...... go to a local carpet shop and ask if they have any leftover remnant pieces of heavy duty outdoor or marine carpet that are big enough to cover your bunks.

#2 Go to Lowes, Home Depot ect buy your pressure treated lumber (in my case was 2- 2X6's inner bunks and 2 - 2X4's outer bunks dont remember the lengths ) Instead of using lag screws again get carriage bolts long enough to go through the lumber and the hole on the arm mount of the trailer, big fender washers and nylon lock nuts, you will also need something to secure the carpet to the bunk my suggestion would be stainless steel staples if you have access to a staple gun.

#3 If your boat is on the trailer more than likely you will need a second pair of hands to measure the next step. Get underneath and measure hole to hole where the mounting holes will line up on your new bunk. When you have them measured and marked drill a hole through the wood just big enough to get the bolt shaft through. Now take your bolts one at a time on each hole placing them through the wood install your washer and nut and tighten down the bolt till the head of the carriage bolt becomes flush with the top side of the wood on the bunk so when you install your carpet there is nothing sticking up under the carpet to damage the hull. Now remove all your washers and nuts and the bolt will be secured into the wood and will not come out. Now install your carpet over the bunks.

#4 Take the boat the water launch it ...... preferably somewhere that the boat can be tied up and not in the way of other people launching. Remove the old bunks and install the new ones provided you have measured correctly it should be a 10 minute job. Just make sure you have all the right sockets and tools needed.

Anyway like I said just my two cents, they will never come loose again and being wet all the time should never be a issue with me again accept for launching and loading. I got a remnant piece of really nice heavy duty rubber backed carpet for $10 not the cheap stuff you see tearing and ripping on other peoples bunks and most likely what they sell you that is precut in a roll. Pressure treated lumber, stainless hardware and stainless staples ran me around $60 if I remember right and a afternoon of my time. $580 to $620 is bunk in my opinion no pun intended lol...... good luck on your repair whatever route you choose.

Re: Boat Trailer Repair

Mine did that and I used electrical tape to hold it in place to load the boat then when I got home I replaced the bunk board and reused the carpet. Pretty simple job not worth paying someone else to do.

Re: Boat Trailer Repair

I agree with all of you...and thanks for the write up SW! I will do them myself...there is no way I am going to spend that kind of money for replacing the boards...and those bolts screwed into the wood from the bottom are worthless! Looks like I have another project...ugh! My wife happily said she would help me out by taking the boat out to have some fun for a day while I go fix the trailer bunks...wasn't that nice of her? :rolleyes:

Re: Boat Trailer Repair

Hypotheticly before things get to loosey goosey - wouldn't a person be able to take those short lag screws out, put a small dab or drop of gorilla glue...and then thread it back in? All while in the garage.

It is waterproof.... cures with moisture even if it was a tad damp... expands, fills gaps /cracks... pretty much like some locktite?

Re: Boat Trailer Repair

You could use some type of epoxy but it is only as strong as the rotten wood around it and would surely fail soon.

Re: Boat Trailer Repair

I had the exact same problem with the screws falling out of my 2007 Q6 SF factory trailer in year 3. After some internet research, I ended up using cypress wood and countersunk bolts. I used stainless staples for the marine carpet. I also slotted the rear bolt holes in the boards. It is AMAZING how much those boards bend under the weight of the boat. You can check this by bolting in the front end of the board, mark the rear of the board over the bolt holes. Then have a big friend sit in the middle of the board and check what happened to the mark.

I know, overkill. I'm guessing this setup will outlast the boat! Good luck with your project!

True but mine were already rotten and the wood was shot so I had no choice but replace everything. Good idea for a newer trailer

Re: Boat Trailer Repair

I was searching the internet and found something called Ultimate Bunk Boards...they are plastic bunks so no carpet or staples are needed. Supposedly they are also very resistant to UV and will allow the boat to slide on and off easier. They have different colors...so I think I will give them a try!

I have read about these and they seem to have good reviews ....... From everything I heard just always make sure you are strap connected to your hoist unless you are wheels in the water launching ....... They seem to be pretty slippery ..... I have always had nightmares more about dumping my boat on the ramp than sinking it without the plug lol

Re: Boat Trailer Repair

I never like to take the winch hook off until it is partially in the water. I have seen too many videos of people dumping their boat on the ramp. I actually can't wait to get these and see how easy they are.

Re: Boat Trailer Repair

Ya me too. I leave the strap and safety chain connected until I am in the water and ready to launch the boat. Last year I watched a guy backing down the ramp quickly and he had to stop. His 18 foot crestliner came off the trailer and sat on the pavement. Luckily his motor was up. It did not do much damage; scratches. Those aluminum boats are tough.

Re: Boat Trailer Repair

This is the rig I used on mine to replace bunks in the back yard. You do need to take some time making sure everything is set up securely so it won't fall off.bunkjack.jpg

Didnt you see above his wife has so graciously volunteered to take the boat out for the day so he can work on the trailer. Prince your one lucky man, she must be one hell of a catch that woman. Taking one for the team and all ..... truly noble! Sounds exactly like something my wife would say. One thing about my wife I can say she never complains about spending money on the boat. I think she enjoys it as much as me!

FastFission,

That is a good idea, I never thought of that.
