I was looking for advice on whether this motor is worthwhile or not. Looking at getting a 2017/2018 Ranger Z519 and both come w/ the above engine. When I called my local service location they said to stay away, that while there are lots 2 stroke out there, the quality of the 4 stroke isn't worth going that route. Said the 2 stroke doesn't last as long and is more expensive to maintain. Are they being melodramatic or would I be better off w/ a different boat/engine? (If I were to get it and something happened, could I put 225 4 stroke on it?)
