Installation 1. Using new gasket, install exhaust manifold to cylinder head. Torque fasteners to 25 lb. ft. (34 N·m). IMPORTANT: See Section 7C for additional information if exhaust risers are used. 2. Using new gaskets, install exhaust elbows (and risers, if so equipped), to exhaust manifold. Torque fasteners to 25 lb. ft. (34 N·m). 3. Coat threads of drain plugs with Quicksilver Perfect Seal and install. Tighten securely.

STARBOARD MANIFOLD: a. Install shift plate assembly on exhaust elbow using hardware retained.
Cleaning and Inspection
b. Connect wires for cut-out switch.
1. Clean gasket material from all surfaces and wash parts in solvent.
c. Refer to appropriate Stern Drive Service Manual and properly install and adjust both remote control shift cables, using hardware retained.
2. Inspect all parts carefully. Machined surfaces must be clean and free of all marks and deep scratches, or water and exhaust leaks may result.
3. Check water passages for foreign material. Passages must be clean for efficient cooling.
5. Refer to SECTION 6B - “Closed Cooled Models” and refill closed cooling system, if so equipped.
4. If more thorough inspection is desired, pipe plugs may be removed from exhaust manifold and exhaust elbow.
6. Reconnect battery cables to battery. Tighten securely.
! CAUTION IMPORTANT: If plugs are removed, coat threads with Quicksilver Perfect Seal before reinstalling. 5. Check for cracks. 6. To test manifold body for leaks, block-off plates, plugs, or short hoses with plugged ends must be used. One block-off plate must have a threaded hole for attaching compressed air hose. Use new gaskets when installing block-off plate(s). Apply 40 PSI (276 kPa) of air pressure and submerge manifold in water. Air bubbles will indicate a leak.
Do not operate engine without cooling water being supplied to the seawater pickup pump, or pump impeller will be damaged. 7. Place boat in water and/or properly supply cooling water to seawater pickup pump.
