Any 2 stroke outboard

Can anyone answer this.
I have put my outboard in my car on a trolly but when it's laid down the prop end is higher than the motor itself.
Could this possibly do any damage to oils going or ending up where it should be. !

Nope. The only oil in it is in the gearbox & that should be sealed.

Generally good practice to keep powerhead higher than prop/gearbox as any residual water in the exhaust can find its way into the powerhead/crankcase through open ports.

Well that's put a spanner in the works I was hoping the set up I have would be acceptable.
Back to the drawing board.
Thanks for your input

The first thing I was warned about when buying an outboard was never under any circumstances to get the leg higher than power head

Ditto to Chipko's comment. I usually raise the powerhead of ours a little on a thick folded blanket.

Is it because of the water may seep back into the power unit

yes.

When the engine is running, the exhaust exits through the middle of or behind the prop with enough volume to clear the "pipe" andf evaporate off anything that is left behhind. When you stop, water rises up the exhaust to match the level of the surrounding water surface, as it has nothing pushing it out.

When you lift the engine out, most of the water will run straight out (you'll see it happening), But there could be a bend or cavity which traps a bit. If you then raise the leg higher than the powerhead, gravity takes over and the water heads for the cylinder...

Most O/Bs tend to lie with the gearbox lower simply because the gearbox is smaller than the "main lump up at the top". As Fenlandser says, a bit of elevation / padding always helps.
