The rest is solid but that must have been left to sit with salt water in it over time. Sides and top of the tall rectangular steel tube frame are solid. This would not be a 50 year fix but in wood terms would be inserting an internal cripple to keep the bracing of the rectangular shape solid. The trailer tracks very well and I like it so will do this rather than welding and over time if anything more happens will just consider buying a new trailer tho I believe this will work fine as it is working as is. I've named the boat K-2 in remembrance of two females in my life now passed on, Karen and Kate. I will order the graphic for the sides in the spring. Going to be in the teens for low tonight here in Chester, Va.

NO!!!!!!!! DO NOT drill any holes in your frame...cross member or longitudinal!! You will weaken it. If you feel that the crossmember is weak either weld a new plate to it or replace it. The last thing you want is to hit a bump at speed while trailering, snap the wood and the crossmember and spill that nice 77' hull all over the highway. This is not something for home repairs. Nuff said.....

It already has four holes drilled through the center of the section...t

I think i'd u bolt some pieces of angle iron to the frame before i went the wood route. Tube trailer frames rot from the inside out.

Lance, from the way you described the repair I was thinking you may have been a crew chief in the AF. I just reconfigured my Magic Lift trailer from a tandem axle to a single. The help and pictures I received here helped so much. Being able to launch the boat and not having to back up to my rear jeep tires was a nice experience. one thing I enjoy more than anything is when someone compliments the lines of the V20 and then to say it is a 78. Wellcraft made it so easy to push the chest out with pride. Maybe if you head back down here to the Ol Geezer state we can strut our stuff.

I'll fill the section but look for the kind of u shaped brackets and bolt it in place with that given your advice.

The last section really does not carry a ton of the weight but I want it to be as good as I can make it. If need be I'll have a u shaped section welded to it.

We will see what I can make work out without drilling more holes and using the holes that are there. I can shape a 4 x 4 to fit inside it with my bench saw and fill the cavity then drill the holes in the wood for the existing holes which should be enough to hold it in place and it will stiffen them up very considerably.. I was just going to use 1/4" bolts but want to be conservative so will go this way. I might also use squared off U bolts but I much prefer through bolts.. Will measure and look. If I remove the back bolts the spreader bar between the rails, last one is affixed to them so I will have to put the stern of the boat on 6 x 6 wood blocks to get the weight off it so the rails can't spread while I do it. Fortunately with two vintage corvettes I also have heavy duty jack stands and can block the back up to relieve the weight while I work quickly.

Seriously... Don't be fooled. Your engine sits at the back of your boat and there's also the weight of the fuel tank and batteries. Don't be fooled by thinking that the rear of the trailer has little weight. If anything it carries more weight than any other section of the boat. I just scrapped a boat last month where the weight of the engine cracked the transom while trailering. (That's why they sell transom savers for trailering). Sometimes trailer manufacturers will put holes in trailers to mount keel rollers and other items, but they usually make those parts stronger to account for the added stress. And, like Phatdaddy said, tube's rot from the inside out, so any water that goes into the tube thru the holes from launching and retrieving the boat stays inside and over time destroys the structural integrity of the part. I'm ex-Navy and can attest to the power of oxygen and salt water to quickly wreck havoc on any metal.

Yep... what they said.

Destroyer, Skool's Out use to call those transom destroyers be cause they would do more harm than good for a transom. The slight rocking of the boat on the trailer would push on the engine because the boat and trailer were not the same if you can visualize that.

I figure they're made by the same folks who make "submersible" trailer lights, rubber coated anchor chains, boat horns, stainless hose clamps with black iron screws, boat trailer brake systems, those hollow black keel rollers that put all the weight on the white plastic bushings and hold water to rust out the roller pin...........

I use http://www.ebay.com/itm/350917672435...%3AMEBIDX%3AIT You'll still get the water in the inside of the roller, but the aluminum pins don't rot out nearly as fast.. especially if you paint them with zinc chromate before you install them.
As for the transom savers, they are only effective if you strap you boat down onto the trailer tightly with a belly strap so it can't bounce up and down. If you use the transom straps that just go from the trailer to the tow rings on the transom you allow the boat to move up and down with bumps in the road, which is what Schools is talking about I think.
My favorite beef is the stainless hose clamps you mentioned, followed closely by the "submersible" lights.
