Very interesting discussion... I am glad my 340 is FWC... The best way to winterize is to spend the winter in the Keys...

Can someone confirm how many drain points are on a 1999 5.0L EFI with an open cooling system?

You have oil coolers along side your engine I pull the hoses instead of trying to take the 1/4" plug out I also pull the lower water pump hose on the engine it holds a lot of water and see no other way to get it out. When draining the block make sure water comes out both sides it doesn’t hurt to poke the drain holes just to break up any rust that might be building up. Pull the hoses on the bottom of the exhaust manifold just to be safe if you have an older boat.

Here is a search on winterizing a Mercruiser it's kinda like here a lot of diffrent ideas.

So my question was how do you make sure the drive is water free?

I pulled the plug from the side of the engine and the exhaust manifold which drained all of the water. I then took the hose off at the thremostat and ran water thru the hose until antifreez came out of the exhaust drain (No antifreeze ever came out of the engine drain).

I also pulled the hose from the power steering cooler (No water came out).

To get antifreeze to the drive do i just keep pouring water in the thermostat housing with the drain plug installed? or do i pour it in the power steerin cooler hose running towards the drive?

 

[millz90]

ok, so i poured less then a gallon of antifreeze in the thermostat hose. Should i pour around 5 gallons?

sorry 1 more question. Do i pour A/F anywhere else or just in the Thermostat hose?

What is the out drive hose? Some one mentaioned pouring it in there? Is that the hose that connects to the cooler? do i pour any in the cooler hose towards the outdrive? That is near the red battery fuse on my engine?

You need to take the t-stat out to get A/F into the block due to the stat being closed when cold. On the cooler hoses just take the hose off and drain the water out and you should be fine also remove the lower engine water pump hose it holds a lot of water.
