2 stroke engines have 2 pistons. 4 stroke engines have 4 pistons.

If the motor requires a special two stroke oil ("premix") with every tank of gas, then it's a 2 stroke. (4 stroke engines do not need a premix) You should be able to buy the mix at any fueling dock or boating shop that sells extras like fuel additives.

Note of interest: The 2 stroke has a high-decibel whine that may exceed legal noise limits in some areas. If you have a 2 stroke, check with your local parks and recreation for noise limit laws concerning the 2 stroke engines.

if you just add the oil into the engine like you would a car it is a newer 4 stroke. Much better on fuel as well and no premixing hassle. I just blew my 4 stroke last summer as the oil injector system failed and there was no warning signal to let me know:(
