If so I'd be very wary, as any very small movement of the boat on the trailer is then transfered through the hydraulics of the engine, which I've never liked the idea of.
Hmmm. If there's movement between the boat and trailer, you don't have the boat strapped down well enough.
I use the transom saver to minimize wear and tear on the motor pivots and hydraulics moreso than preventing damage to the transom (my hull is welded 1/4" aluminum, and I doubt any engine movement is going to do much to that.) In my case, the support runs between the lower unit and the hull, rather than between the LU and the trailer (can't get to the trailer without having a dogleg support bracket.)
Trailering over less than glass-smooth roads will cause the motor to bounce around, penduluming back and forth. Preventing that is why I use the bracket. That force is absorbed first by the motor pivots, then through the mount to the transom. The transom saver not only transfers some of that energy to a different structure (usually the trailer frame), but also prevents the penduluming in the first place (the penduluming of the motor greatly increases the forces seen by whereever it's applied to.)
Using a block of wood between the engine mount and the engine (or the ram-mounted blocks such as the M-Y Wedge
) will relieve the stress imposed on the pivots, but will transfer it to the transom. If you're sure your transom is beefy enough, fine. If there's any question about it, well, I'd suggest going with something that transfers at least some of the load somewhere else.
That's just my opinion;
