the laying down of four strokes

I have a mariner 4. It was the aux on the last boat and gets used on the dinghy. Its fine in the boot of a car laid tiller down as per instructions. Fine that is until wife decides that the car in front is driving too slowly, overtakes and puts many a boyracer to shame on the twisty lanes of dorset.
It took ages to get the oil out of the boot carpet. The engine now lives upright on a frame in the van during transportation......and I drive!
 
HMMM interesting reading this.
I have a mariner 4 stroke and I have left it right side up but flat on its side in the locker now for about 4 months. Should I be worried?
 
Look at the sticker.

on my recent PBO play day I noticed that the eight outboards we tested were very particular abut the way they want to be laid down

although all were handles to the port side.... why... half wanted to be laid handle down and half handle up

why can't they make a four stroke that can be laid down or even turned upside down without leaking oil or wrecking a spark plug

I am onlly a simple ag engineer so I know only the basics

help me vic

I'm sorry, I just don't see what the problem is, you goes to the shop, you looks at all the pretty engines, you chooses one, you get it home, read the book of words, look at the engine and see the sticker on it that says "lay down this way up"

How hard is that???
 
Feckin' Hell Lakey, you had to explain it to 'em with a picture???:D:D

There must be some elegant way of desiging a four stroke so that it can be stored or even run at any angle.

The thing that amazes me is that they can standardise the side the tiller arm is on but not the way the engines are laid down

and.....

why is it always on the same side

I presume because most of us are right handed

maybe they should make left handed outboards

Agree, I am left handed and I find it very annoying having to use a right handed outboard.
 
aha

Isn't it to do with the direction of prop rotation, so that the weight of the helmsman is on the side of the boat that will tend to rise in the water?

great idea

is it true though?

does anyone know if it is

if it is then the cack handers would need an engine that ran the other way

Who could have predicted that a thread about lawnmower engines could drift to cack handers, square earthers and people who question the whole concept of a fact

What happens when you bought it on ebay and it doesn't come with a book of words and the sticker's missing?

I bought an engine like that last year; fortunately it's a 2-stroke so the issue doesn't arise.

You log onto the forum, admit to being a complete plonker for buying an outboard without an instruction manual and to now having all the engine oil in the car boot

Every body will frantically Google to try to be the first to find you an on line manual.

A dozen people will tell you all about every other make of outboard known to man except the one you have bought.

Dylan will ask why you cannot have a left handed one that will work upside down

Lakey will post a link to a Tohatsu manual.

Somebody will upset somebody else and insults will fly.

Eventually you'll get fed up and find the manufacturers website and an on line manual for yourself

How does the oil get into the cylinder?

Seems to me that the only route in for oil to get into the cylinder is past the piston rings or down the valve guides and past an open valve. It would appear unlikely for these paths to allow the cylinder to fill. However, I know from bitter experience that it can and now I am having difficulty in startiing the outboard as there doesn't seem to be a spark.

With regards to the laying down I am sure that it was laod on the correct side but it was in the back of my car for a week as I didn;t want to haul it out and then haul it back in again (very heavy and awkward - 9.8hp). Won't do it again as I now strap it upright to my passenger seat.

Any thoughts or suggestions (not rude ones please as some people seem to regard this forum as a vehicle for abuse).
