The boat looks like this.I don't know what jet pump system the Sea Ray uses. My first jet boat was a Browning with a Berkley jet and 455 Olds engine about 30+ years ago and it had a clean out port on the top of the pump inside the bilge just aft of the intake grate. You could open the cover on top of the port to get out any debris. It was a real thrill when the boat was in the water and water would shoot out the port and into the build.... but that would often clean it out.
First thing would be to crawl under the back of the boat if its on a trailer and look into the intake grate on the bottom of the boat with a flashlight and see if there is a twig, plastic bag or other debris that could be disrupting the water flow and causing cavitation preventing you from getting on plane.
Here is what the Berkley Jet Pump looks like and the clean-out port and intake.... just to give you an idea of what you are looking for but it won't be identical to these pictures.

We're dealing with more weeds around here.Same engine and pump I had on my jet boat in 2001 never had an issue with it getting on plane unless weeds were in the pump and that boat was the one I built my first steering system for , plus the same one I developed the reverse move for removing the weeds it was a regal rush but a lot of them had 90 and 120 hp force outboard motors powering the jet pump
