I was in need of a sound clip of a jet ski and I couldn’t find anything without violating copyright or creative commons so I had to go to “pay-for-play” route, so to speak.

I found sounddogs.com and they had a slew of sound clips for jet ski sound clips.

Also, they included this pdf for terms of use.

Be on the look out for the use of jet ski noises in my group’s radio show.
