carry and transport outboard motor
I just bought a Tohatsu outboard motor from the boat & sportsmen show. It's a 6HP motor so will fit my inflatable perfectly I hope. My reason to buy a small motor is for the easiness for transportation.
I downloaded the manual from internet. To my surprise, the manual said I have to carry and transport the motor vertically. The manual also mentioned that I have to drain the gasoline and engine oil if I really want to laid down the motor into my car!! but still need to raise the motor head 2 to 4 inches in order to avoid leakage.
This is driving me crazy.... Hope someone can tell me this is a over shot
Thank you in advance! John

I have no idea if I'm correct but I bet it's lawyer talk for if the fuel drains out n you start yourself on fire, well they told you so.

If it is a 4 stroke it should be up right. The gas issue is self explanatory no!

It shouldn't have oil in it new and you can transport them generally on the side tiller up depends on crankcase filler location

Usually can't lay down 4 strokes, the oil will migrate into the cylinders. They even recommend not leaving them tilted up on the boat when parked. Not an issue with 2 strokes.

My 5hp Mercury can be laid down tiller down (shifter up). I carry it around for a spare and lay it down in the bow of the boat because I don't like how it clutters the back of the boat if I have it on the transom.
Isn't the Tohatsu a Mercury copy? Or is it a Yamaha copy?
Either way I was surprised to hear it can't be laid down. I'd look for more info on that.

Spot on!!
Perfect reason to stick to 2 strokes for smaller motors. Four strokes are heavy, and not nearly as convenient for back country packing, though they do run quiet and idle nice if they are in a permanent mount situation.

Motor can be laid down with tiller down
The manual that I have says that your 6 hp Tohatsu may be on its side with the tiller down only. For some reason, the 2.5 hp Tohatsu is the other way up. The diagrams on p. 28 show how not to do it. The motor on its side is tiller up which is wrong. Memorize: tiller down .
This is to prevent oil draining from the crankcase into the cylinder. When I bought my motor, the mechanic said that if you forget and get oil in the cylinder, the motor will be difficult or impossible to start. You have to pull the plug and pour out any oil. Clean the plug if necessary. Top up the crankcase and it should start.
Hope this helps.
BTW Tohatsu makes the small motors that Mercury and Nissan relabel.

Thank you so much for all the inputs. The manual says:
I don't know what to do... who would drain all the engine oil in this case?

They have changed the manual somewhat. I don't really think they will have changed the motor so I would bet that they are erring on the side of caution. I have carried my motor on its side, tiller down, many times with no problems. I have a friend who has done the same with his 9.8 hp Tohatsu.
If you drained the oil, why would you elevate the power unit to avoid oil spillage as in the second bullet point? There wouldn't be any oil to spill.
I would give it a try, with the oil in it. I wouldn't anticipate a problem, but the mechanic told me the fix is easy.
If you are still in doubt, find the local Tohatsu dealer and ask there.

Thank you SK270! I really need to ask why the manual is different from mine and yours. I bought MFS 6C.

The reality is nobody is going to travelling with their portable outboard vertically and nobody is going to be draining anything ...... and for 50 years people have been transporting and using portable 4 strokes with zero issues myself included.
just find out "which side up" and enjoy the motor.
Years ago I built a plywood/2x4 "cradle" to keep my outboard secure and properly oriented (in my case tiller handle up) in the bed of my truck.
If you orient it correctly you should have zero issues.
I do always, however, stand it up when we get to our destination and/or back home on a saw horse.

Tohatsu makes all Evinrudes 15hp and down. Nissans are rebadged Tohatsu and 30hp and down Mercury outboard are all Tohatsu. In short Tohatsu is he second largest outboard manufacturer in the world. Decent motors from what I’ve read and a bit cheaper then the name brand models.

I’ve heard there’s an issue with the float in the carb if laid down on the wrong side but I haven’t chased up any real data on it. You haven’t got a sticker on your engine?

Got my brand new Tohatsu 6HP....however, I realized today this new motor was sitting in the shop upside down for who knows how long when I went there to pick it up. I found it out by my name on the packing box today. Will I have any trouble with this motor? I know there is no engine oil but I guess the factory must tried the motor with engine oil before shipping out... what should I do? hopefully no harmful to my new motor...

Had a Honda 4 stroke at one time.
I'm sure that it said right on it to lay it down only on one side.
