Re: How to place my motor for trailering??
Yes tilt it up unless you have high clearance.
However, you can trailer a 25 on the tilt latch all day every day.
You probably should tie the motor down to prevent a freak event of the motor bouncing up, the latch operating against its spring and closing, and your motor falling down right when you are crossing a speed bump. Also to keep it from flopping from side to side, if your steering is loose.
Transom savers don't save transoms (except maybe rotted ones that should be replaced anyway). transoms can handle motors.
If your latch seems frail, put a block of wood up under there, but tie it both to keep it in place and to prevent it from falling out and hitting the car behind you (same with transom savers). For years I used a hammer handle on my 18 that didn't have a latch.
