Best Transom Saver for Yamaha 250 4stroke?

Used traditional transom saver in the past, and it finally broke. What does the OB suggest going forward?
TIA

Yamaha makes one now. It looks like a giant black dildo inside of a PVC pipe.

Do you strap the back of your boat to your trailer? If so use the traditional transom saver setup, this is the best way to actually help your transom.

This is the best I have seen, My-Wedge.
I do not understand these "transom savers" that do not reduce the flex applied to the transom when towing. If the motor is not anchored to the trailer someway then all of the weight and movement of the outboard is still transferred to the transom.
It is simple dynamics. These will reduce forces to the trim/tilt system, but the transom will feel the same forces as if there was nothing supporting the motor.

You my friend are smarter than most. I've replaced transoms and done lots of fiberglass work on boats. The new Tampon Sleeve "Transom Savers" are a crock. But they sell because they are quick and easy to throw on and roll.

My use application is to "save" the trim unit/rams, not the transom.
There is no "saving" the transom. My transom aint goin nowhere.
If you use the traditional stick type that attach to the trailer, every bump in the road is being transferred up to the lower unit where it attaches. Not for me.
The trailer bounces much more than the boat on the bunks.

Then you're doing it right.

I'm not saying they work well, but they do reduce the torque on the transom. The downward force of the engine is still on the transom, but you've removed a lot of the torque arm length, therefore reducing the twist force. That torque on the transom is going to be a major part of what causes it to fail. I definitely think going to the trailer would be better, but to say that the other types don't do anything is false.

-Strap boat to trailer
-Don't deadhead the hyd. trim into the transom saver

I can't argue with this.
To the OP I would suggest getting another transom saver like the one you had.

Yea they don't save shite

This is correct. The Yamaha one I referred to is a rubber material so that it absorbs some shock between the motor and the trim rods.

The forces that the ENGINE places on the transom when running esp in heavy seas is MUCH greater than it gets from bouncing down the road.
Yes the torque/angle of the motor is more perpendicular to the transom, but the force is greater from the push of the engine.
Each his own, Ive nver used a stick saver.

You really dont understand their purpose do you. They wedge the motor to keep it from moving or flopping around. Ive used both and towed from here to floida and back. No issues with either. The traditional kind doesnt support the weight of the motor either, it props the foot to keep the motor from moving also.
Alx, the one in the video is either shitty or wasnt installed correctly. It def didnt have the collars to keep the motor from turning.

The purpose of the transom saver is to reduce flex on the transom caused by the torque of the motor bouncing up and down.
The traditional type ties the foot to the trailer which the boat is strapped to this making it (almost) act as one unit. The trailer bears the brunt of the foot's downward force. The transom would see mostly downward force from the engine and only a little rotational torquing.
With the wedge, the torque is reduced to only the portion lower than the wedge, but the whole system ties to the transom. The transom bears the entire brunt of the torquing force.
Think of how a hammer pulls out a nail.
