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.
