Is a 1984 Yamaha 90 Oil Injected 2 Stroke motor considered an "Old fashioned conventional motor"? Though the author didn't mention his type of OB in this thread, it is listed in his PP.
When I had a 1984 Evinrude 115hp OB, I used to run it dry after each use. I had the motor for many years without one problem at all.

Its an old wives tale that was never proven by facts, The same can be said about cranking a cold engine before it fires, (no lube). Its amazing the crazy things old wives talk about when men folk ain`t around. I`ll keep doing it, and I`m sure with no trouble. We know the problems old gas can cause when it sits in the engine, for a lengh of time. The fuel pump is electric it fills itself when the key is turned and the bulb is pumped.

I've seen my share of broken outboards with scored cylinders and other damage. Who's to say some of the behavior discussed in this thread didn't contribute to such damage? Just because one's motor runs without issue doesn't mean there hasn't been some sort of accelerated wear due to something I believe no manufacturer recommends. If the motor isn't used on a regular basis, chances are total hours will be low even for motors that get up there in age. I doubt the practice could cause much concern done periodically.
I don't run the gas out of my outboards and have found other means to thwart issues caused by storing gasoline for periods without usage. It seems many are comfortable with the practice of running the fuel out and in the end its an individual decision... as long as it doesn't cause a warranty issue I suppose. Regardless, good discussion.

Regardless of whether you run it dry or not, if it's going to sit for any length of time there should be some fuel additive in the tank and it is reccomended that you fog the motor if storing for a long period of time.

My 2 cents...Fuel Stabilizers are intended to be used when you buy the gasoline. Stabilizer maintains fuel integrity. Once integrity is lost, stabilizer won't bring it back.

I think the line of demarcation here is that you can run out an engine with carbs, but not injected engines. There's no reason to do it on an injected engine in the first place. I heard a story, key word here is heard, where a hand disconnected the fuel line on an injected engine that was on a tender aboard a larger boat. He then went to clean something on the other end of the boat. When he returned, the engine had continued to run on the oil pumped into the injectors and had a big mess to clean up. I didn't see it, but just read it on a forum like this.

I ran my Honda 4 stroke dry based on reports that the carbs are prone to fouling.
In the 20 years that I have had a 1966 Evinrude 33 HP motor I ran it dry the third year I had it and the cork carb float crumbled. now I'm back to just parking it for the winter. It starts right up every spring and has given me no trouble..

As a follow up to what Tom was saying, I run the Johnson 115 2-stroke dry when it will sit for more than a week. That said, the only time I run the Verado’s “dry” is right before winter layup. Per Mercury instructions, after running treated gas through them for 10 minutes, I turn the fuel selectors to the off position and let the motors run out of gas. That’s it – unlike the Johnson where I will crank/choke it a few more times.

With a fuel injected motor...you shouldn't have to run it dry. None the less, just do what the owners manual says and you'll be fine. These newer motors are finicky.

I have an even better idea.......live in S Texas and there is no winterization period.

actually it is designated the central gulf coast if you watch the weather channel, but compared to the state, we are only about 100 miles or so as the crow flys north of the Mexican boarder. Dallas, which of course is north, is a good 8 hour drive from here.
Temps here rarely see the 50's, and only for short periods although we did have snow on Christmas eve some years ago, first time in the 13 years i've been here, and it reached the 20's for a day or so, then was back in the 60's. Now, the heat in the summer is a whole different thing, dang hot here from June to mid Sept. My favorite time of year is mid Sept - late Nov, and March - June. Only down side in the March - June is it can be very windy, and seas are usually pretty tough.
All in all, its a great place for boating pretty much year around!

What Duf says is truth! The weather in CC is beautiful year round and it is about an 8 hour drive from Dallas. Which BTW, I hope to make that 8 hour drive again soon!
Blue skies, deep blue water and warm tropical breezes about sums it up for that part of the world,

I just do the Etec winterization too.
Our 40 hp Johnson has sat around with fuel in the carbs and now it won't idle.

Duf,
Just had to comment since originally from the Valley. You're lucky to be there in CC.

Have to agree Bill, i guess its why i"ve stayed here for so long. Looking to upgrade to a larger boat (at least this is my excuse) to enjoy more of the boating longer when it gets a little rough in the winter and early spring, but temps are still very seasonable most of the time.
