The draw-back is. when we cut the ignition in a FI engine, we also cut the fuel supply simultaneously and prior to the rotating assembly coming to rest. [links]

In lieu of Fogging, an oil enriched fuel mixture is introduced into the fuel system. This mixture can be introduced via the fuel filter cartridge. here

1. Use caution with any single point drain system. these systems prevent "probing" of the engine seawater drain ports! more
1. I've always done my own winterizing and was very happy with the single point drain system on the new Merc.
This is because the fogging oil may inadvertently enter and affect the FI air sensors. more
The 4.5L comes standard with Adaptive Speed Control, which automatically maintains engine rpm regardless of load or water conditions. The result is increased throttle response and a sporty feel.
Need an Owner’s Manual for your Mercury engine to perform maintenance, replace parts or just learn more about your engine? Mercury has made it easy for you to purchase a printed copy or to download and print your own copy.

Featuring a host of engineering innovations, the 4.5L series establishes new standards for power-to-weight ratio, driver experience, acceleration, durability, and ease of maintenance.
Thanks to its new, long-runner scroll intake manifold which draws in more air and converts it into additional torque, the 4.5L delivers a ground-breaking power-to-weight ratio and gives you V-8 power in a V-6 package.
Designing a V-6 block solely for marine use allows Mercury to build the 4.5L with the ultimate protection system, using cast-iron componentry where the engine intersects with seawater, and using corrosion-resistant aluminum and composites everywhere else. [links]
The 4.5L’s newly designed rear-facing throttle body, anti-whistle throttle plate, engine cover and mounts, lightweight flywheel, fuel-supply module, and structural oil pan all work together to deliver a superior idle, smoothness and low vibration. Resulting in an exceptional driving experience. [links]
that said. i understand that warranty programs are riddled with "we do the maintenance or else". I purchased a new furnace that had a full warranty as long as I paid them $400 a year to clean it. i get it more
is it out of style to simply drain the water out anymore? more
Another question was, the manual and the video specify that this is not sufficient for winter storage. Merc says that because this is only step one of the whole process. Those steps include, oil change, antifreeze, run engine on home made cocktail fuel (2 stroke oil + stabil), drive lube, etc. The manual does cover most steps except details about adding antifreeze. The Merc tech person said the best way on these engines is to warm them up on muffs, drain water, and then run engine again introducing the antifreeze. Not sure why they do not list that in the manual. (cover their butt?).

Reconnect the closed cooling system hose or reinstall the drain plug, then fill the coolant reservoir with fresh coolant. Mercruiser Horizon engines require a special long-life coolant; some other Mercruiser engines can take ordinary car engine antifreeze mixed 50:50 with water. [links]
Properly winterizing your boat's engine at the end of each season makes for a more reliable, longer-lived boat. Many popular Mercruiser sterndrive and inboard engines use a closed cooling system that adds many years to the engine's life but requires a bit more care than open systems. Winterizing time is the perfect opportunity to take care of the closed cooling system, helping you ensure a trouble-free boating season next year.
Look up the coolant change intervals, and the type and amount of coolant required, in your engine's manual. Some newer Mercruiser Horizon engines only need a coolant change every five years. Other models need new coolant in the closed-loop side every year or two.
Drain the closed side of the cooling system if you will be changing the coolant this year. If the drain plug is hard to reach, disconnect one of the coolant hoses from the water pump. Several gallons of coolant will gush out; have a couple of buckets ready to catch it. Changing the coolant ahead of schedule is a good idea if you've been using the boat a lot. Some boaters change it every year; Mercruiser allows up to five years for a Horizon engine in typical light-duty use.
Fill a five-gallon bucket with a 50:50 mix of water and non-toxic propylene glycol plumbing antifreeze. Close the raw water seacock, disconnect the raw water intake hose from its strainer, and stick the hose in the bucket of antifreeze. Have someone run the engine for a few seconds until you see antifreeze starting to trickle out the exhaust pipe, then shut it off. The antifreeze will protect the raw water side of the heat exchanger from damage in below-freezing weather.
Open the cover of the raw water pump and check that the rubber impeller is intact. If it looks dry or cracked, replace it. If the impeller is missing blades, their remains are probably stuck in the heat exchanger—check it again for debris, then replace the impeller. Do the same for the closed cooling system pump. [links]
