There is a manifold block on the bottom of the gimbal housing that needs to be removed to replace the lines from the pump. Manifold block is held up by two nuts/studs. Remove the nuts, drop the block down remove old lines and gasket material. Install new gasket and lines, attach manifold block and connect lines to the pump. Keep in mind the lines are up/down specific so label them accordingly

What dubs283 said.
Also, it's best to use a good quality flare nut wrench so you don't strip the fittings.
Might want to tie a line to the old hose, pull the old hose with the line out and then use the line to pull the new hose in place.

Most likely mercruiser #1, possibly #2. Depends on the serial number of the engine

Can only recommend the factory (Merc) manuals. All the others (seloc, clymer, Gregory's) are full of errors and omissions...

Tools needed. 7/16” socket and ratchet, 3/8” flare nut wrench. When you pull the block down you will be able to remove the 2 lines. Just be sure to mark which one is front and rear and to be safe replace them 1 at a time. The gasket may tear and also the aluminum that the block is made from may be eroded away due to galvanic action. There will be grime in the cavity that causes that.
These are what you will need.

I think I may have hit one with my 24‘ Campbell Daycruiser.
The La. Wildlife and Fisheries just trapped 2 of them in the New Orleans Municipal Yacht Harbor. Any gator under 7’ gets relocated and anything larger gets a bullet. Every so often they are spotted in the local drainage canals. Nutria and Japanese carp keep them happy.
Now get wrenching on your boat.
