What is that trailer rated for,

how much tongue weight ? looks to me the axles need to come forward, as you are overloading the front one....

I personally like my axles further back, all my trailers have towed better that way. That's in conjunction with the proper trucks suspension and hitch height. If the trailers level the axles suspension is designed to share the load with equalizers.

The frame flexing along with improper suspension geometry seem like more important problems.

And for some reason I don't like the idea of a spring over.....I don't think that's the best way. I feel there should be a way to make spring under work perfect.

Longer shackles, heavier duty springs, shorter spring pads. Hard to figure out without better pictures.

You could try contacting dexter axle they are pretty good help over the phone. Plus thier website has lots of info.

That trailer cannot handle that boat there is not enough structural support , its bowing badly , I would hate to take it down the freeway !!!!!!!!!!

Trailer is rated for 12k. Here are some pics of the tag along with one side of the bare axles. all hangers, shackles and spings look to be in good condition. It actually trailers nice, I don't have a comparison so my view may be skewed but it pulls straight. Only issue is the deflection in the trailer now acts as a spring when going over road changes which is why i added the strap over the nose of the boat, that keeps it sturdy. a bandaid I know now which is why I'm trying to remedy this. A new trailer is not an option for me right now.

What does the boat weigh ? I had a Vanguard trailer under my 42 fountain it had a upper structural support frame that ran the length of the trailer that thing never bobbed or deflected a bit .The main frame is just not tall enough look at myco trailers .

NADA says boat weighs 7,700lbs so adjust for load and we should still be well within the trailer specs. The boat itself isn't too heavy, what the previous owner did caused the deflection. The bow/sag will be fixed by welding support along the length of the trailer forward the axles, once straight the trailer equalizes the load just fine.

As for height clearance issue with the axles. Dexter says either go ahead with the over under swap or upsize to a heavier spring. I'm gonig to try an 8k spring. if that don't work then the spring over will have to happen. New trailer is out of the price range right now.

7700??? That seems awfully light for a Scarab III. I'd be guessing more like 11,000 or so.....

7750 from NADA
8200 net from marine bluebook

Front axle is hitting the frame because the equalizers are allowing it due to the nose down attitude of the trailer putting all of the load on the front axle.

It may tow like a dream according to you but that load is certainly not distributed evenly among the axles.

That tiny frame is scary looking.

Your best bet is to hack the excess tongue off that is not needed and weld a second tube under the one that is there,

Second weld a truss down the length of the trailer rails and it might get by,

Have you measured the tongue weight and trailer weight with the boat on it ?

If not I suggest you go do that 1st

Spending any money on heavier springs is futile as the whole problem lies in the poor geometry of the axles and equalizers because of the incorrect distribution being applied .
