The movie title I'm looking for was about a teenage boy and his friends who go overseas to rescue the boys father who is being held hostage. I believe his dad was a pilot that had crashed and got caught. I can remember it had a good jet boat chase down a river with big canyon walls. I believe it was late 80's- early 90's.

Iron Eagle? Iron Eagle (1986) - IMDb (http://www.imdb.com/title/tt0091278/)

It's been awhile since I've watched Iron Eagle. I'll have to see. I was thinking it was something like "the rescue", or "operation rescue."
For some reason those titles are stuck in my head. Thx
