It's the same with all brands of motors.
If they won't hit the road trailer with them down. If they can hit the road trailer with them up.

The bracket on the motor is not designed to take a load while trailering. It is there to prevent the hydraulics from leaking down while the boat is parked. The motors likely will hit in the down position. I have twins on my Conquest and rigged up a couple of transom savers that work well. I bought a pair of the adjustable transom savers that cradle the lower unit on one end, and have a "U" shaped casting on the other end that typically goes over the rear most center roller on the trailer. I bought a couple of rubber "V" bow blocks that are used for a trailer bow chock. It will monunt between the "U" bracket on the transom saver. Drill a hole through the "U" and use a long bolt to hold it in place. That "V" block now rests an the bottom rear trailer crossmember and the transom savers cradle the engines which are tilted up about 40 degrees from vertical for road clearance. I've trailered my boat this way since '98 about 1000 miles/yr over some nasty roads with no problems or signs of stress cracks anywhere. I also use good ston rear tiedown straps so the boat does not move relative to the trailer. A picture of the transom saver I used (unmodified) is @
The Bow block that fits inside the lower "U" bracket is:

Since we have the same boat, trailer & engines, see Cetacea Page 11, 4th picture, for my engine trailering position. This is the spot where the power trim first rests the engines on the "trim" running rods (with the big ball bearing on the end), when coming down from the unsupported "tilt" positions. You can tell when you're in this mode by the change in trim speed, and the sound. In this position, the engine is as high up as possible, but still firmly supported.

And for you I/O folks, trailer with the drive UP and use trailering clips on the rams.
