Welcome to the forum.

Here are some links for your boat. It is listed as a manual head. There should be manufacturer ID that could point to a manual.

A plunger is probably a good starting point. Shut off and bleed the fresh water pressure to limit overflow.

Attempt w/ push stroke, tipping to the side to limit suck stroke.

Determine if manual flush or Vacuflush. The Vacuflush has duckbill Joker valve that can invert on a plunger suck stroke.

You are welcome.

Good luck w/ the new boat.

On mine I use a file briefcase filled w/ printed documentation, from Sea Ray and that I collected over the years. I also have many computer folders filled w/ lots of documentation.

Note that a plunger has low effect on the push stroke, but massive effect on the suck stroke. The push stroke is safer. It might be required to perform short / sharp suck stroke impulses to break up the clog.
