If the boat has sat for 21 years. You have a lot of work prior to any splash.
Your fuel system will need to be completely pulled apart and cleaned . The tank will need cleaning, the carb will need to be rebuilt
Your ignition system will need to be serviced
Your drive will need to be pulled apart and a new raw water pump.
Your drive will need to be pressure tested
The motor will need to be inspected, new fluids and filters
The hydraulic fluid in the trim system will need to be replaced
The trim tab system will need service
The hull will need to be inspected for rot
The trailer will need new wheel bearing seals and the wheel bearings regressed
The trailer brakes will need to be serviced/replaced
The tires on the trailer will need to be replaced
Then you can worry about the one hose we have no idea that you are talking about
