There are at least 5 "right" ways. I will give you mine, then others can give you theirs.<br /><br />Pull the fuel line when the engine is at idle. Let it run until rpms increase. At the first sneeze, cut it off.<br /><br />Good luck. :)

Ditto with JB on that! Soon as it coughs, shut her down!

Here's a more paranoid and labor involved method.<br />Remove the intake cover if necessary and drain carb bowls.Just another way to release fuel from carbs.I do neither cause mine is started a minimum of once a month.

My way very close to JB's. I do the same thing except instead of shutting it off when rpm go up or it starts to die I pull the manual choke. Read this is a Mag as a motor tip.<br />Reason they gave is gets all the fuel out of the carb but also sucks in more fuel/OIL to bearings and Cylinders. Oil is the main reason. richer fuel and OIL to coat the Cylinders and bearings.<br />They also said would make it eaiser to start mext time. I not sure about the easier to start part as mine still takes one or two pulls. That is my way.

I dont believe that running the gas out of any ouboard motor unless it is going to sit for longer than 6 months. No one has ever proven to me that it needs to be done. My dad was a Merc master mech for 15 years and I do what he taught me, not saying that it is right or wrong, but he told me that unless your going to store it for more than 6 months that it is really pointless with all the additives and conditioner that are in fuel now. I have never done it and neither hase he. Just my opinion though, not saying that it is right or wrong either.

The reason I ask is that you'll never get it all out. I would put Sta-bil in the gas and run the motor for five minutes with muffs on. Disconnect and your all set. Plus the gas will be all set too! ;)

Stauter,<br /><br /> I have not run a motor out of fuel in 15 years. A good dose of stablizer in the tank your last trip out will get it through the whole fuel system. You also can use it all the time for periods of infrequent use, that is the best. Running them out of fuel is old school technology, you need the fuel/oil to lubricate the motor. Periods of extended storage require fogging the motor to prevent rust. Drain and refill the gearcase??

Re: The "right way" to run gas out of a motor?

Just for the record...<br /><br />Yamaha recommends idling 4-stroke outboards until they runs out of fuel and stall (at least this holds true with my F225's, F115's, F50's, F9.9's and F6). With 2-strokes they recommend the fogging/stabilizer routine (at least this holds true with my 40,50, and 115). I can't find the owner's manual to my '99 Evinrude 15, my 7.5 Merc or my other Yamaha's, but if I remember, it's the same theory. <br /><br />It would be best to do what the owner's manual suggests, especially if the outboard is under warranty. The manufacturer's know what they're doing. :)
