Re: movement of transom in splashwell
If I am understanding you correctly, your transom is flexing in the middle with the weight/movement of the engine. If this is the case, I can tell you what I did on a friends boat to remedy this problem until we have a chance to fix the transom perminently. I bought a piece of 3x3 aluminum angle and cut it to fit just inside of the gunwales. I then supported the engine with a floor jack and removed the upper mounting bolts. I clamped the angle to the transom covering the upper mounting holes. I then drilled holes in the angle throught the existing holes in the transom where the bolts were and reinstalled the bolts through the engine mount transom, and new angle. This created the stability that the transom needed. Seems to be working well.
