usually near the throttle mechanism, there's a screw you can adjust to increase the throttle cable resistance, thus preventing the throttle from falling back. I faced similar "problem" when I got my boat new. Later I come to understand that it was left resistance free to prevent users running the new engine at high rpm continuously. After engine runs-in, I adjust the friction screw and now throttle works great.
