I'm a huge fan of 2 stroke motors.
simple design and perfect for outboards in their operation range.
I owned a fitch 175 which was a nice motor. much better performance from a 2 stroke or 4 stroke in terms of holeshot,running speeds IMO. with the added benefit 2 stokes can run at WOT all day long.
2 strokes are a better option on smaller boats I think. small 4 strokes tend to be a bit doey.
I would happily own a large 2 stroke if the oil cost wasn't ludicrous. that's the biggest reason id never own one again. above 2000rpm they use 50:1 which costs a fortune if your a big offshore user.
but the biggest advantage of 4 strokes are engine hours. if your a heavy user they are good for at least twice as many hours.
I think its horses for courses when it comes to motor selection. get what suits your usage the best.
