In my opinion the transom savers that run to the trailer put more stress on your transom than not using one.
With a trasom saver you are putting hydrolic aided stress on your transom year round (every day sitting in the driveway still hydrolic stress)…especially if you trim down too much when putting the transom saver in. If you trim down too far with the transom saver installed you are basically “lifting” the back of your boat off the trailer with your motor.
Now its not like you are really lifting the back of the boat off the trailer but you are definitly taking boat weight off the bunks/rollers and forcing your motor and transom to carry that load. if you don’t believe me put your hand between the motor and the transom saver and trim down like you normally would…its a lot of pressure for the quick second you hit the trim down button when putting the transom saver in.
When you have the transom saver in you are directly taking every shock from the trailer frame and transfering it directly to your transom. All the flex that occurs in the bunks/rollers and trailer frame is being transfered to the transom through the transom saver.
without the transom saver the max stress on the transom is only created by the motor itslef. the stress created by the motor moving around is pretty minimal when compared to the torque of 200+ horses on a hole shot the transom is designed to handle.
The transom saver is a false sense of security…you are basically “pre stressing” your transom so you don’t notice the minimal flexing that may/may not occur.
And the guys transom that was flexing 4″….he has to have something else seriously wrong with it for this to happen and I don’t think a transom saver is going to solve his problem.
