How to Winterize a Volvo Penta 5.0 GL Marine Engine
Question: How do I winterize my boat that is equipped with the Volvo Penta 5.0 GL Marine Engine? I’ve heard that I can just drain the engine and manifolds but don’t need to do anything else. Is this correct?
Answer: While draining the engine and exhaust are important aspects of the winterization procedure they certainly aren’t the only aspects of boat winterization to be concerned with. Complete winterization involves fogging the engine, stabilizing the fuel system, and preparing the coolant passages with Propylene Glycol to prevent corrosion.
