In the past, I have mixed 50-50 antifreeze and water in a 5 gal bucket (Merc 3.0). I have opened the three drain valves (block - manifold -elbow) and let all water drain. I then connected a teel pump, using plastic 5/8 hose to the block drain valve and started pump, when antifreeze started comming out of the manifold drain, I closed that drain, continued to pump until antifreeze came out the elbow, closed that drain, continued to pump until antifreeze staretd to come out the lower end. I have done this for 20 years with no issues. Now I have a volvo Penta 3.0. Do you think this method is good for the Penta ??<br /><br />Also, I would like to drain the bowl on the carb, any way to do this ??<br /><br />Thanks<br /><br />Sooner
