Author Topic:   Help with Cox Trailer tilt Questions?

The trailer under the Outrage is a 1984 Cox Trailer. It has a tilt function that should allow me to launch and retrieve the boat without dunking the hubs. Problem is I don't really know how to use it? Anyone got a good explaination on how it works? Is it truely as simple as backing down the ramp, releasing that safety chain and poping the lever?

Thanks for any help.

Not quite that easy. The way a boat is balanced on a trailer, there is more weight in front of the axle(s) than behind (usually 60% / 40% of weight).

A tilt trailer allows you to manually lift the front of the trailer to allow the boat to slide off. Theoretically, you do not have to back a trailer in as far if it tilts than if it doesn't tilt. But, without knowing what your ramps are like, I would venture to say that you must ALWAYS submerge the axles of a trailer to launch it. Otherwise, the boat is not supported by the water and the rollers and/or bunks are dry and not sliding. Even with a tilting trailer, you are not launching that bad boy.

Tilt trailers are common, but not required. Big trailers and, to my knowledge, all aluminum trailers lack them.

I have a friend who has never used the tilt on his trailer. My current boat trailers do not have tilt. When I have had tilt, I used it only about 20% of the time.

Just my dos centavos worth.

Thanks for the info. I guess i'll sink the trailer when i take her back. I'm not so sure the rollers work anyway so it may be hard to slide her off tilt or no tilt.

Anyone else with a tilt trailer that uses the tilt feature?

Kamie, I also had a Cox tilting trailer for my 18 Outrage and currently have one under my 15 Super Sport. Assuming that the trailer is the right size and fit correctly to the boat, the center of gravity for the boat will be and should be ahead of the axle when the boat is pulled up to the bow stop.

What I do is undo the safety chain and latch that prevents tilting before I back down the ramp. I leave the winch cable and safety chain connected to the bow eye. Back down the ramp (assumes a descent ramp) until the wheel hubs are just above water level. Then launch the boat the same way you would normally. With a little shove the boat should roll off the trailer easily and when the center of gravity of the boat passes to the rear of the axle, the trailer should tilt. Be careful here because the boat may have a tendency to accelerate a little bit when it tilts. I always have a bow line in hand and the trailer's winch cable is still connected at this point so there is a little friction to retard the descent.

Retrieval is the same but in reverse. Don't forget to redo the tilt latch and safety chain, otherwise the trailer will flex at the tilt joint underway. With the tilt feature, it is rare that I ever have to have the hubs underwater.

Thanks Peter, I will try when i go to launch her. One issue may be that I don't think the rollers roll any longer. Once she is back in the water I plan to replace the rollers and change the wobble rollers to bunks.
