Re: Motor supports when trailing or storage.
To each their own but I always used the "Transom Saver"! And here is my take of that. Yes the OB running does impart a lot of transom forces, but like everything made, the transom is made of materials that will over time fracture from operational fatigue. Nothing actually last forever. So any time you can prevent more transom forces, the longer it will last. So call it a transom saver or simply securing things to protect longevity, I use the one in your picture, the Transom Saver. It keeps your engine and transom and the trailer all together to reduce any forces on anything. And remember the longer the distance from the pivot point of attachment, the great the forcers are applied, like a torque wrench...longer applies more torque, simple physics... I don't think folks would allow their truck tailgates to flop around for the exact same reasons... JMHO but not the only one out there for sure!
