Another winterizing Question Please

"I know the routine as far as winterizing an O/B engine, although not completeley sure as to all to do with an Inboard/out, Volvo penta 4.3
as far as I can tell there is no fresh water container/reservoir to be found, assuming water is pump up thru the leg/foot? as would be on an outboard, and then released when boat is removed from water, I would usually start the boat briefly out of water to force out any remaining water in block, However! I'm not entirely comfortable not knowing all the water is out for sure on a Inboard... will this in fact remove all water?
and will simply draining the outdrive be enough?
should I fog the 4-brl carb? as I would the ones on an O/B engine?

should there be a drain plug in the bottom somewhere to drain any water left in block?
Thanks for any Help

"you will find a drain on both

"you will find a drain on both sides of the block. also on the bottom of the manifolds. disconnect any low lying hoses and drain off water. don't neglect the hose from water pump to thermo housing. it will hold water, and freeze. could freeze water pump as well. if you are in a harsh winter area, its a good idea to run R.V. antifreeze through system as explained on many previous posts. fogging through carb is O.K."

"Thanks Scott,
I found the drain plugs just where you said they were,I wasn't at all surprised to have found that there were still close to 2 gallons of water left in the block, would had frozen for sure as cold as it gets here in Ga.
I removed the hoses from the water Pump and let water drain out, I also drained the foot, all is good there no water found in oil,
Now all I need to do is reconnect the hoses run the antifreeze through, then stabilize the fuel tank and fog the carb...
is there anything else I should do?
Thanks again.

"sounds like you got it covered. store with the drive down to prevent water buildup from weather, and bellows "set" and pray for rain. S."
 
"Tim,
I'm surprised it

"Tim,
I'm surprised it gets that cold in GA, nevertheless, it's always a good idea to winterize if the boat is laid-up for the winter. A few questions: Is your boat raw or fresh water cooled (FWC)? If raw water cooled, yes by all means drain the block and exhaust manifolds (flush with nutra-salt to stop saltwater corrosion if needed). If fresh water cooled and you have the correct mix ratio of anti-freeze to water, then draining the block may not be necessary because anti-freeze should not freeze. However, you can still drain the block if you doubt your mix of anti-freeze, that's up to you. Do you have an owner's manual for your boat/engine/outdrive system? If so, the winterization procedure in your owner's manual should have a comprehensive winterization procedure for your system. If you don't have an owner's manual, you can download one for free at this site:

Good Luck,

"Bobz.... yes it gets quit cold here in the south
just a couple nights ago temps drop 29* although warms back up to 60*s in the days,when actuall winter does arive temps can drop into the teens
and has been known to drop 05*plus chill fact. which is -27 below freezing, weather has gotten to be crazy down here in Ga. temps expected tonight 27* but then warming back up to the mid 60* again, Ha! I'm sure you guy's up Nth
probably pray for days to be in the 60's
"warming trend" so's you can take your boats back out.... Heck we would as well here if there were any water to float a boat in. Not much rain all year... actually I only took the boat out about 5 times past summer untill last time out a ran upon an unmarked sand barge and thought I had toasted my prop, luckily it was just sand...............
The engine is all fresh water cool never been in salt water, I'm not sure what you mean by the term
"correct mix ratio" I don't know this engine to have a Holding reservoir for antifreeze/water mix?
although I was going to simply hold up one of the large hoses from the top T-stat housing and poor antifreeze in there surely the antifreez would make it through the engine block if perhaps I started the eninge for a moment or so? I also do klnow when I drained out the water there were no sign of antifreeze in the water, was clear..
I have no Manual for this boat, purchased it early in the year from a guy that didn't know anything about boats and provided no manual...
Thanks for the link I will download this manual."
 
"Tim,

"Tim,
Some boats are equipped with a heat exchanger where the primary coolant is the raw water (the water the boat is floating on) and the secondary coolant is the freshwater (water and anti-freeze mix) which circulates through the engine. The typical mix ratio is 50/50 or 1:1 (one part water, one part anti-freeze). If you have a mix that is more water than anti-freeze you increase the chance of your engine block freezing and possibly some bad things happening like a cracked block etc. If your boat is run mostly in lakes and rivers (fresh water), then a raw water cooled engine is sufficient but, an engine that is run mostly in salt water and is raw water cooled increases the chance of rapid corrosion of the engine block, heads, intake manifold etc. That is why saltwater boaters install these heat exchanger kits aboard their boats so the coolant that circulates through the engine is anti-freeze and, using a separate pump, the raw water is used to cool the anti-freeze in the heat exchanger.
Good Luck!
