Having some issues controlling the rpms on my 96 Volvo penta 4.3 engine.

When I start the boat it idles fine but if I increase the rpms it gets stuck and doesn't back down to idle. It will stay around 1500 and then maybe a minute later drop back down to idle. I am not sure what is causing this or where to start looking first. Any help would be appreciated!

Thanks
