Please help this has been driving me crazy for years... what is the name of this 80's kids movie, its based at the same time of flight of the navigator, It may even be the same boy, anyway this boy is out walking in the woods (with a girl I belive)and comes along a lake or resivore. There's an old abandon mine shaft or shack on the beach, anyway they are in a boat I think and the water starts bubbling like crazy and they get scared and take off. The girls dad is a forest reanger and finds them along the way. They keep going back trying to figure it out.. as it turns out its an old man ing with them trying to scare them off, the bubbling was an old crane in the water...

Not much info to go on, sorry.

Please help!

It's this one (aka The Quest)
