4s mowers are not recommended for hilly sections, as the oil all goes to one side of the shallow sump, and they run dry
plus they tended to be heavier]]> Mon, 22 Aug 2016 06:46:27 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=119787&PID=1651783&title=storing-4stroke-outboard-tilted-up#1651783 <![CDATA[Storing 4stroke outboard tilted up : Cigar wrote:I always thought...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=119787&PID=1651779&title=storing-4stroke-outboard-tilted-up#1651779 Author: pjc

I dont know about 4S outboards... except when storing a vecile type 4S one sets it up right so the oil in the crankcase doesnt get into up into the cylinders, and or the oil pump get exposed. The latter if left long enough may not prime as the engine turns over resulting in turning over firing with no lube and dry cylinders.
 Cooling draining... again dont know how 4S  a cooling galleries/ ports are set up But on a johnson / evinrude the Service/ Repair manual recommends storing vertical so all the galleries can drain dry, preventing internal corrosion.
And if wintering...to blow the galleries, in particular the speed ports with air.
 I would think it safe to ASSUME a 4S cooling galleries, impeller, pumps, ports etc to be similar to a 2 S.

The caution in doing this is leaving down, forgetting and moving the trailer, hitting the skeg on the ground going over a bump. 
Another issue is if uncovered or no engine cover is water in a storm going in thru the vents and laying inside around the power head... even left upright in a heavy  wind storm.

 And a side note on storing carbed @stroke tilted...the oil and gas drains out of the back of the carb... leaves oil around the base of the powerhead... I dont think that is a bad thing.
With most of the fuel /oil mixture drained out of the carbs, and fuel evaporates, it may tend to leave the carbs dry.. which in long periods between use may cause corrosion drying of gaskets etc in some engines.
Left up right leaves a oil in the carb... but will smoke up when 1st fired for a minute or so.

If not using the engine for a while.. any engine, vintage car, rod etc.. winterize it... gets a bit messy when re use but worth it .. no stuck rings, lubed when fired up etc.

“...tilting a 4-stroke outboard motor at 45 degrees when it’s stored on a trailer or boat lift....stowing a motor vertical is just fine for a 2-stroke motor, because a 2-stroke outboard has its oil mixed in the gas, so there isn’t an issue.”
This statement in itself seems really outdated to me. For a start is your DF90 an early carbed motor? If it is a later fuel injected motor then no issues. They seem to be quoting a carbed 2-stroke that has oil already mixed in the fuel i.e. premix. No comparison in motors. Also my Suzuki agent said always store in the vertical as this totally drains all of the water from the power head which otherwise could turn into a corrosion issue later if trapped.

I think its crap too, had one guy tell me that a yamaha rep had told him to only use the flushing port when he got his motoer home, as it didnt run hot enough to oil it all up inside the motor...sorry but i will always run mine at home in a drum, want that salt gone and the thermostat to open.

I think on balance its better to store vertical so the cooling system drains out.  Cooling system corrosion or salt accretion seems more of a risk to me than small amounts of oil sneaking past the rings.

A 4 stroke petrol engine can last along a time with oil getting past the rings ...

If the boat is put away with the motor vertical then any oil around piston, rod and gudgeon is going to pool in the bottom of the bore (especially if the motor ends up past-vertical when the jockey wheel is wound up) and inevitably a small amount will seep past the rings when the motor cools... which means you might get a teeny tiny bit of oil consumption and a slightly 2-strokey smell when you first start it. But since the oil lives in the sump on a 4 stroke, I can't see it being a huge issue.
 
Put another way... I have 2 Subarus and on both of them the cylinders are horizontal 99.9% of the time and I don't have oil consumption issues.
