Playmobil Underwater Motor

There are several issues with this motor assembly. First, the instructions do not tell you that you need to screw the white locking pin in when installing the battery. I noticed the Philips head indention and surmised how to install it (it is not screwed in when new, just pulls out when first opened). The on/off action is very touchy. Just a slight turn and it turns on the motor. It would be better if it required a bit more turn. The motor itself slides onto the mount on the bottom of the boat. When you turn the motor on by twisting the front, it pops off the bottom of the boat because the motor plastic flexes on the mount and the water tight seal on the motor makes it hard to turn. This is frustrating to the child. The motor pops off easily if the child grabs it or if they are playing and they bump it on the wall of the tub/pool. Don't expect a lot of speed. The prop is small (good) and can be stalled easily (safe). My grandson liked it for a couple of minutes but then resorted to speedboating by hand!
