Winterizing a Volvo Penta 5.7GSi SX-M boat engine

Its time... time to start the countdown until we can get back to important things, like boating. But in the meantime, better be sure your boat is ready for the cold winter ahead!
Its winterization season!

In this video I show you my process to winterize this Volvo Penta engine. This same process can be adjusted and used on a number of boats.
I also have a tidbit about the mercury central drain system, as well as mentioning that you need to be incredibly cautious if your boat has certain features like ballast tanks, heater core, hot water heater, and other things that may need special attention.

This is the most basic process to winterize, it works on a trailer, on a lift, or in the water. The big key is getting the water out and getting antifreeze to displace any remnants of water.

There are other methods, I've seen people use flush muffs, or just drain and not refill with antifreeze, or install a engine bay heater. I prefer this method, but to each their own. I've done it this way for years and it has worked successfully on every boat I have serviced for a long time.
