No but they will work tremendously. My last boat had a very negative degree transom built in. Hole shot was immediate regardless of load or balance. However, trim up quick so not to bow steer. Not a replacement for tabs. Tabs adjust ride. For hole shot the wedges will beat out tabs as tabs need the boat moving a certain speed to work. Motor tucked way under does not need speed to push bow down. The angle naturally pushes boat up and bow down.
