Your transom takes more of a beating on the water than it takes on the trailer.
I completely disagree with that. Simple physics would show that a motor tilted to the normal angle while trailering will put much more force on the transom than one at a riding angle in the water. Also the water slows the force of the strain the motor puts on the transom while on the water.
What's not to like about a transom saver? With one in place, a triangle of bracing is created and that, in itself, is very strong. Anything less in my opinion is considerably less.
The M-Y wedge nor the other thing posted braces the motor to the trailer. All the force is still absorbed by the transom. You guys to know that stressed fiberglass cracks, right?
Has it become "uncool" for bass fishermen to use transom savers? IMO these new things are trying to solve a problem that doesn't exist.
