Fuel remains through exhaust is minimum and besides will have engine off when diving. 2 strokes compared to same 4 strokes size have near 10 KG weight difference. 4 strokes consumes less fuel, but need more specialized maintenance. Some swears by 2 strokes, some by 4. Both have pros and cons as everything in life.
