Dan, we have a lot of questions in Australia on how to transport boats properly when we are traveling. What are the main things we are looking for?

It’s pretty important that we take good care of our portable outboard when we are transporting it. There’s a few main points that we can learn for all outboard motors. Focusing on prevent water from getting into the engine. We want to prevent oil from leaking out into the car. And we want to prevent fuel from leaking out as well.

Once we’ve had the motor in the water. There is water in the exhaust section or lower area of the upper motor. Good idea is to once you’ve pulled it off the boat is to hold it upright for a few minutes so the water can drain out.

Never lift the outboard with the propeller higher than the outboard engine. In that case any water that remains in the exhaust area can run into the engine. And we don’t want water into our engine.

So after the oil, I think you mentioned about the fuel.

Nice portable outboards have their own fuel tank. The fuel has a vent on the cap here. We want to make sure that that is tight. A good practice is to turn the fuel tap off. Turn it off while the engine is running allowing the engine to stall out. What that will do is run out any residual fuel that may remain in the engine. To prevent that from leaking out as well.

We want to make sure that the orientation of the outboard is correct when we lie it down flat.

I noticed that on the back you have a curved handle so I’m assuming that prevents you from trying to lie it down that way. Therefor taking the carbon from the bottom.

They have thought a lot about that. Good selling point of this engine is that it can be laid down on all three sides. And not from that forth side.

Like all of Yamaha’s portable outboards the 6hp four-stroke is ergonomically designed to make lifting, carrying and storing the motor as easy as possible. Of course, placing the motor on a blanket or map is always a good idea too. Saving it from scratches and protecting your vehicle.

The 6hp 4-stroke Yamaha is equipped with four different manual tilt positions, to facilitate both shallow water operation and also to allow the leg to be lifted clear of the water for launch and recovery. Obviously these different tool positions are handy in operating in shallow waterways or coming into shore.

Another really neat feature of the 6hp 4-stroke Yamaha is the option it offers to attach an external fuel tank for a longer run for extended use.

To fit an external tank simply close the fuel tap for the built in tank, then attach the fuel line from the external tank to the fuel fitting on the front of the motor. As shown here. It is as simple as that. To greatly increase your operating range.

And then with the motors, the portable engines, I’m guessing there is a fairly good security risk at times when people are out and about.

The portable outboards are considered quite a prized items by thieves, and can be easily stolen, so there are a couple of preventative devices that Yamaha have available. One of them is this thumb screw lock. They prevent the thieves from getting to the thumb screws and undoing your outboard motor from your boat or wherever you are storing it. Very heavy stainless steel that can’t be cut through very easily. I think that would be a good deterrent in and of itself if a thieve were to see that. It also prevents your screw from unwinding and falling off your boat.

It is also important to take security for your outboard engine one step further by purchasing one of these individually coded Yamaha DNA anti-theft kits. Each kit contains a special tagging pin which is used to apply thousands of tiny, uniquely encoded nanotags to various areas of the motor. These tiny tags cannot be removed and are easily read under magnification. They make it simple for the police or boat brokers to instantly identify stolen outboards.

Choose clean, grease-free surfaces and don’t apply the nanotag emulsion to moving parts or load-bearing surfaces. The more areas you mark, the better. Once you’ve tag your motor with the DNA kit, apply the stickers provided to advertise the fact.

These are a great deterrent to thieves who know that it would be almost impossible to unseal the stolen motor.
