That's correct. The pump for the engine is attached to the engine, via brackets and drive belts. Then you have the 3 separate pumps for the ballast tanks. I have a 2014 242 Launch and my 3 pumps are all mounted on a panel board on the passenger side rear of the boat. All the way in the back of the ballast locker. I had to remove the carpeted wall to get to them. Very much a pain to find the screws under the carpet.
