Detach the exhaust headers from the vehicle engine using appropriate tool. Remove and disassemble the carburetor. After that you can now remove the pulley as well as the water pump from the engine. Then you will see at the base of the engine the lead freeze which you will need to pop and plug out. You can now remove the motor mounts from the block.

Install the heat exchangers, water cooled exhaust manifolds and the exhaust manifold gasket. At the front of the engine connect the marine water pump. Then connect the hoses of the heat exchanger to the water pump. In the engine compartment of the boat install a through-hull raw water intake, the remaining hoses as well as the water filter.

On the water cooled manifolds connect the exhaust tubes together with the needed clamps and gaskets. Once the engine is installed on the boat you can connect the remaining parts of the exhaust.

Check the carburetor and detached the fuel line fittings. Then attached the gas tank, fuel pump accessories, configured marine fittings for the rigid line or you can also used air craft rated fuel line as long as they are configured prior to marine use once the engine is installed. Having a 1 or 2 fuel filter will be great for the fuel supply system.

Into the intake manifold put in the carburetor flame arrestors. Put back the carburetor into the intake manifold. Prior to adjustments modify the throttle connection to the throttle control and cables of the boat.

On the engine block install the brass freeze and attach the marine motor which will be mounted at the engine block. You can now fill the crankcase of the engine with the appropriate and hi graded marine motor oil. Lastly on the engine compartment install external oil filters for the fuel system.
