Engine Fogging when Winterizing ?

I was reading on Yanmar help page about winterizing engine. I saw something I have never done before, which is to spray CRC longlife into air intake while cranking engine with stop button depressed. i guess this fogs the cylinders and inhibits moisture. My engine is a 3YM30 with 460 hours on it.

Anyone out there do this? The boat is in Maryland, so decently cold winter possible lasting about 3-4 months.

If you press the stop button while spraying oil in....the engine may start.

I'm sure it's a good thing to do, but it is difficult unless you have a helper. I just plug up the air intake and exhaust with oily rags. So far, knock on wood, no issues.

Re: Engine Fogging when Winterizing ?

Cranking the motor w/o starting may just suck in some moisture. I would think that residual diesel fuel would be oily enough to keep the cylinders dry through the winter.

In winterizing my diesels I;
Close the raw water thruhull valve.
Run fresh water thru the raw water system (I have a T-fitting set up).
Pull the water pump">raw water pump impeller and drain out any external water that I can.
Drain the wet lift.
And, I keep a 100 watt light bulb burning next to the motor to keep it dry.

Keeping the whole inside of the boat dry is the best thing one can do for winterizing.

If the motor can not be kept dry, like an open decked power boats, then spraying them down with WD-40 helps to keep off corrosion.

My Yanmar manual says to pull the injectors and squirt in motor oil, crank over and reinstall injectors. But I've never had to go that far. Maybe if I were to store it for years, I might go to that extreme.

Different strokes for different boats.
