You want some support of the motor. Transom saver is one way to do it. I have that on my Caracal cat--and it came with the boat. The only issue is that there can be some slight disconnect between the trailer and boat--vibration, going over bumps etc. I have never had any issues. Mine is on a Suzuki 140.
For all of my other boats, I have either used the MY wedge (hard rubber) which goes over the longer single lift cylinder arm between the motor and cylinder. Some use PVC pipe in there--it can scratch. and is not as strong. The MYWedge can get soft with the heat--and if too much pressure, creep down. Another option is a piece of wood between the engine bracket and support on the engine. This is probably the most commonly used "device". A 2 x 2" piece of wood--perhaps OAK? A round closet rod 1 1/4 to 1 1/2 " wooden towel is cheap.
I also like to put my engine all of the way over to one side to release any pressure on steering ram. Talk to the hauler. Is the boat going on the trailer, //road, or on a transporter? (Flat bed or boat carrier?) If on your trailer--be sure the tires are new--(less than 5 years old) that wheel bearings are in good condition, well greased. Be sure that the hauler is both licensed to haul commercially, that he is bonded and has insurance. Also be sure that your insurance is in effect and covers the boat in transport. $1.50 a mile is a decent price. The distance is about 3000 miles. If I have a boat shipped, I try and find a hauler who has taken a load near to where I want to pick up the boat, and has no scheduled return load. You might get a better price...or not.. I like to have a good coat of wax on the boat before cross country hauling. If possible have the windshield covered. My black out curtain fits on the outside and protects mine. Be sure the hauler either calls you each day or has a tracker, so you can check on the boat.
Congratulations on the purchase of a boat!
