I've been out using the transom extender a couple of times now. The extender itself seems to work just fine. No apparent flex or anything.
The tricky part turns out the be what height to extend to. My transom extender adds 140 mm to the transom which is a bit more that the normal 5-inch (127 mm) difference between a short shaft and long shaft. Still this was not enough. 155 - 160 mm would have been better.
