80's Movie With a Ferrari Boat

That Ferrari Boat Car Conversion though

From time to time I remember that there was a movie I watched as a kid in the 80’s where they had a Ferrari that converted into a boat. It was really cool, every time I remember about it, I ask people, and nobody ever has a clue. So now I decided to blog it so it would be documented and I would not forget it. Maybe someone will have an idea.
