4 stroke outboard storage in cockpit locker

[Telstar26]

I'm looking to replace my Parker 21's ancient 5hp 2-stroke with a modern 4-stroke, probably Tohatsu or Mariner.

However, when I'm not using it, it sits in the cockpit locker in this position:

But I notice in the users manual that it should be stored either upright or like this:

How important is that? Would oil really leak out in the wrong position - where from? (The dipstick?)

I believe the leak is from the sump past the piston rings and into the cylinder(s), causing damage if you then try to start it with the cylinders half-full of oil.

I've just bought a new (to me) 2-stroke

I have a Yamaha F4 that can be laid on any position. It's a great engine, quiet and the range is astonishing, but it has been stolen once, and attempted twice. Much heavier than the two stroke Evinrude I had before it, though.

It is very important that the engine stored as specified; oil will go into the cylinder and or in the carburator

+1 from bitter experience. Even storing it on its side should be for only a few minutes. Left mine (Tohatsu 9.8) on the correct side in my car for a week. Oil everywhere - combustion chambers and carburetor.

Is the ancient one still reliable? why change it?

The 25-year old one still runs, but the leg is badly corroded and cracked, and the gearbox is only held on with one bolt not 2 as I overtightened it and broke it, leaving half a bold embedded. So I don't think it's got much longer to live!

Thanks for the advice everyone.
