Suzuki 115 4 stroke question

6 posts in this topic

I own a 2001 Suzuki 4 stroke 115 HP. I have had a great experience with his motor. Last summer on one occasion and once this past week I pulled away from the dock and idled for about 30 seconds and hit the throttle. At about 3000 rpm the engine kind of surged and slowed a couple times. I backed her off the throttle and idled for about a minute and a half and took off with no further problems. I am wondering if this is a sign of a problem or do I just need to warm it up more or quit running ethanol? Pure premium gas is hard to find where I fish. Any ideas? The fuel filter is new.

You may want to lay off the ethanol gas and purchase non-oxygenated gasoline. I believe you can add products to your gas now if you use ethanol gasoline. Most gas does have a percentage in it.

Lawman,

I have the same motor also since new in 2001 and have nothing but great things to say. How may hours are on the motor? When is the last time you changed your spark plugs? Fouled plugs will cause situation you discribed.

Just had new plugs put in. This is a great motor, only 300 hours on it. I think its the fuel but have not had any problems ever. I will try the non=ox and see what happens.

If it's carbureated, might want to pull the carb and clean the jets. If you add some cleaner to the gas, it will probably work itself clean. But that sounds like a typical spring symptom with a lot of motors that sit all winter. Could just as well be stale gas too.

Did you prime the primer bulb till it was hard prior to taking starting?

It could just be warm-up time related.. at this point I don't think I'd do anything until it becomes more repeatable.

    • Three favorites at the moment.  By the time they upload, I may change my mind.
    • A few from Maplewood State Park on April 16th.  Non-professional, but they stood still long enough for me to get 'em.
    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...
    • Colonel E.H. Taylor Small Batch Maker's Maker's 46 Bulleit Glenmorangie Highland Single Malt   Copperwing Distillery in St. Louis Park has a nice smooth whiskey. Supposed to introduce a new bourbon in a couple weeks too.
    • Hey featherslayer, you gonna register that nice bird of yours pretty soon?
    • cool find!  sure looks like a Swainson's.  
    • Great info.   Thanks Steve!   Jim
    • Came across this hawk on Earth Day at the edge of town. I've been told dark morph Red-tail, dark morph Swainson's and dark morph Broa- winged. Anyway, it's a dark morph some kind of hawk.
