1. Start the engine.
2. Check for any leaks.
3. Check the oil pressure.
4. Check the water temperature.
5. Check the exhaust gas.

Step 10: Install the Engine in the Boat

Once the engine is tested, it is ready to be installed in the boat.

1. Bolt the engine to the engine mounts.
2. Connect the transmission to the propeller shaft.
3. Connect the fuel line to the fuel tank.
4. Connect the water line to the water pump.
5. Connect the exhaust pipe to the exhaust manifold.
6. Connect the electrical wires to the battery.

Step 11: Launch the Boat

Once the engine is installed, it is time to launch the boat.

1. Start the engine.
2. Put the boat in gear.
3. Steer the boat out of the dock.
4. Enjoy your new boat!
