How to winterize a boat. Step by step easy to follow instructions of how to prepare your boat for winter. I did this to my 4.3 mercruiser but, it is similar to the 5.0 and 5.7. Volvo and OMC can be done like this too. I have other videos of my 3.0.
Step 1, Add seafoam or stable to your fuel tank and run it for 5 to ten min.
Step 2, Can skip this step, pull carb cover off and spray fogging spray into the carb till it kills the motor to coat the cylinders with oil to prevent rust pitting. Better for long term storage.
Step 3, Unscrew all 5 block and manifold drain plugs to get water out of motor.
Step 4, Pour Marine/RV coolant directly into hose until it comes out of the top and lower end.
Step 5, You don't have to but, I repeat step 3 and then 4 again just to make sure the coolant made it to all parts of the motor.
Step 6, Drain lower end. Recommended to refill it.
All done.
