How do I identify 2-cycle or 4-cycle?

[Jake Miller]

I have a 15HP Evinrude; 1995 or 1996 (no i.d. plate but label inside cover says FEB 06 1996). How might I determine whether this is a 2-cycle or 4-cycle engine?

Thanks...Jake Miller

If it has a dip stick it is a 4 stroke,but I do not think that Evinrude made a 4 stroke in 1995/6 so don't worry.

They actually did make em in 2 and 4 stroke.....

Check for a dipstick or model number from id plate on transom bracket.....a 4 stroke will have an "F" after the "15".....

If it is a four stroke engine it will say so on the engine cover. If you still aren't sure, remove the cover and look at the engine. As mentioned, if you find a dip stick like the one in your car (if you ever check that) it is a four stroke. The engine looks entirely different than a two stroke in the area of the spark plugs. Two stroke heads are basically flat. Four strokes have intake and exhaust valves so look for camshaft covers. If the engine has a sticker on it that says fuel/oil mix 50:1 it is a two stroke. Four strokes have oil in the crankcase. Also look for a label on the side that says something like "transport on this side". Four strokes need to be layed on one side or the other to prevent the crankcase oil from getting into places it is not supposed to be.

If you ever have lifted it of the boat and carried it anywhere, you would know if it was a 4-stroke....

Thanks for all the replies...I know now that I have a 2-cycle, so now I can proceed.

Thanks again...Jake Miller
