See full version: Water drain plugs locations on Mercruiser V8. (pics)
Im kinda confused, I have the merc 5.0mpi that has the single point drain plug in the front that drains the water out. Does that drain all the water out eventually or do I need to find all these other drain plugs and take those out too? Thanks good info and pics. more

On all of our boats the manifold drains are on the back of the manifold. Dont see a problem with taking those hoses off though. Pretty sure the engines Ive drained have not had 5 gallons of water in them. more

We also have the Mercruiser 5.7 available as a block without the heads, known as a Mercruiser 5.7 short-block. more
We offer the Mercruiser 5.7 in different packages depending on your needs and budget. more
For the block with the heads already assembled, but without all the tin, we offer the Mercruiser 5.7 long-block. here
Propylene glycol antifreeze with a rust inhibitor is approved for use in the raw water cooling system for cold weather storage purposes ONLY. However, if your engine is equipped with a closed cooling system, you should always use a 50/50 mixture of ethylene glycol antifreeze and water in this system. Even if you don't live in a freezing climate, you should still use an antifreeze/water mixture rather than plain water. Antifreeze mixtures have superior anti-corrosion and boil over protection properties.
Do I need to put antifreeze into the raw-water/seawater section of the cooling system after draining?
Do I still need to have winterization performed by my dealer if I have a self-drain system on my engine?
Mercury Marine Quickstor can help maintain fuel systems in storage. It contains oxidation inhibitors to reduce oxidation and gum formation, metal-chelating agents to protect metal components from corrosion, water-absorbing agents to reduce the presence of free water, and dispersants to help suspend and disperse debris. When placing the boat back in service, be sure to reopen the fuel valve to the engine. [links]

Every 300 hours or 3 years, whichever comes first.

If your boat's configuration does not allow you access to the drain plug on the bottom of the engine, remove the dipstick. Insert the probe and hose of the crankcase oil pump into the dipstick tube. Push the hose into the tank until it "bumps" on the bottom of the oil pan. Place the pump's discharge container into the oil drain pan or another receptacle suitable for receiving the spent oil. Pump the oil from the crankcase. When the pump no longer discharges oil, stop pumping, remove the probe from the dipstick tube and re-insert the dipstick.
The amount of oil you must add to the engine varies according to the model year. Engines made from 1998 to 2001 have a larger crankcase than those made between 2002 and 2009. The earlier engines require 5 1/2 quarts. Those made between 2002 and 2009 have a smaller crankcase and require only 4 1/2. Remove the oil filler cap from the oil filler, located on the right rocker arm valve cover -- the cap is clearly marked with the word "Oil" in capital letters. Pour the appropriate amount of oil for your model year into the filler. When you've finished, put the filler cap back onto the filler. [links]
As with any oil change, the festivities move more quickly if the oil is warm. Warm oil -- like any fluid -- flows more quickly than cold. This means that you need to start the engine and perhaps take it for a day of boating as a precursor to the oil change. In any case, you have to stop the engine before you begin the process of removing the oil. If you have sufficient room beneath your engine to fit in an oil change pan as well as your arm, you can remove the drain plug from the oil pan with a 7/8-inch box-end wrench and allow the oil to drain. As the oil drains, stick your fingers into the stream of oil and rub them together to feel for bits of metal. [links]
Look on the center of the top of the engine, at the front of the manifold -- the end where the belts and pulleys are located. You'll see a plate that lists the manufacturer, GM, the engine's size and horsepower and the model year. The model year is important because the oil capacity and the location of the oil filler on engines made from 1998 to 2001 is different from engines made between 2003 and 2009. [links]
Based on the Chevy 350 engine, the Mercruiser 5.7 L 350 Mag MPI has many qualities in common with its landlubber cousin. You may not be able to gain access to the drain plug on the bottom of the oil pan. This means pumping the oil out of the crankcase rather than draining it unceremoniously into a pan. You also need to know the model year, stamped on the information plate on the starboard -- right -- cylinder head. [links]
