Towed my Achilles/Honda 40 for years without a problem. I used a motor support bracket, though. Never liked seeing the motor pendulum back and forth.
Basically, any trailer that will support the tube bases (where they meet the floor) or further out, and supports the transom, should be fine. I've seen custom rigged trailers with triple bunks for cradling the tubes, and I've seen what looked like a flat piece of plywood with wheels. As far as I can tell, they all worked.
