run dry?

10 posts in this topic

Just bought my newest outboard to date. 1996 Evinrude 15HP. I got to run it yesterday and it absolutely purrs!! One pull start first time and everytime as we motored about and fished a few different spots. It idles down perfectly. So here's the question: How do I keep it like this for a long, long time? At the landing when we are done fishing should I let it run out of gas? I've heard this before but I'd rather it come from a reliable source. Also any general tips for keeping it going strong. I'll be duck hunting out of this this fall so it's going to see alot of time on the water and is gowing to have to work pretty hard at times. Thanks.

I would recommend running Sta-Bil or Seafoam in the gas all the time and leave the gas in the carbs (don't run it dry).

As far as making it last, keep up with the fresh treated gas, use a quality oil, change your impellar every 3 years, and your gear lube every year.

Do not run into rocks with it grin

That thing should last a lifetime if treated well.

x2 on using Stabil in the gas whenever you fill up the gas tank. In the fall change the lower unit oil, hit all of the grease zerks with grease, and fog the engine whenever you let the engine sit for more than a month (prevents corrosion). Periodically you may want to use carbon guard or run a heavy dose of Seafoam through it to clean.

Stabil keeps the gas from breaking down and essentially varnishing the carburetor.

I would put another plug in for running Seafoam in the gas. I run Seafoam through everything I own with an internal combustion engine from time to time(lawnmower, auger, outboards, truck, car, auger, chainsaw.)

It may not be a bad idea to run the carbs dry if you won't be using the motor for a long period of time(like storing it over the winter).

The simple maintenance has already been mentioned but I will say it again. Lower unit lube changes and grease zerks. If it doesn't have a decent stream of water running out of it change the impeller.

Check behind the prop from time to time to make sure there isn't fishing line wrapped around the shaft. That will eat up your lower unit seal and cause problems. If at the time you are changing your lower unit lube, you notice water mixed in you may need to change that seal or possibly your water pump gasket.

Excellent advise above. I also remind you that using your outboard often is beneficial to it's own performance. Most outboards have problems because are used a little then left alone for a long time. Seals dry, carbs gum up, pump impellers dry up, etc.

As DTRO said, keep it in tip top shape and will last forever.

I have the same motor on a 14 foot boat. I love it. Starts and runs good. I never run it dry. For winter storage I drain the lower unit fluid and replace it, fog the motor and I'm good to go till Open water again.

A two stroke should never be run dry without using a fogging oil. When the gas is gone the fumes will race the engine when lean and you run the risk of piston and cylinder damage. Also on the lower unit do the oil change in the fall. Some wait till spring. If water gets in there and freezes over the winter it will trash the lower unit.

Hopefully you add fuel stabilizer too...

Yep I forgot to mention that. I do use fuel stabilizer. Good catch.

    • Keep an eye on those trees. They tend to jump in the way when your not looking.    won't be the same without ya. 
    • Truth be told it was the outstate money that originally built the metro into what it is. Without that funding St Paul would be nothing more than St Peter is today. 
    • Can't argue with the last part
    • I wonder if a person gets an extended warranty if that will help?  I have a 2011 with 5.3 silverado and all is good today so I'm thinking og looking into that.
    • My last kayak adventure was less than stellar wound up in the drink. And it was a cold drink at that. A very memorable paddle up to that point. It was the first time I had ever been on the water with snow on everything. It was awesome.    Alas, my 'yaks are all put up for the season now. Waiting for next years adventures to begin. 
    • I am toying with the idea of doing a little calling this weekend. The moon is nice and dark, so the first and last few minutes  of daylight might make something happen. It all depends on what I stumble into for sign. The majority of the deer hunters have been done for a while, so the free meals are going to be getting harder to come by. 
    • The fans I was talking about are 12 volt and only 1" deep. Putting them under the heater might not do the job because the heat from heater rises. If you have room in the lower cabinet on your heater you could mount one fan inside and blow the heat out the grill on the front of the heater.
    • I thought last night's game was surprisingly entertaining considering how low scoring it was for most of it. Not sure if people outside of MN and TX would agree. Rudolph dropping that ball in the end zone was devastating - IMO it was a bigger play than the final one. As much as I hate to see us continue to lose, I honestly have never seen a team lose so many starters at key positions and still be competitive. Says a lot about our coaching, depth, and players buying in.   Will be interesting to see what we can do with our OL without having a 1st rd pick this off season. As others have said, it wouldn't be a bad strategy to use every draft pick we have on the linemen.      
    • Yes. Unlike you I have a job and a life.   I'll just say that whatever it's about you are right because that's the only thing I could ever say that you would possibly agree with me on. I won't get in the way of your libertarian fantasies.
