Yamaha 225 4 stroke v's Bombardier Ficth 250.

RS,
Just something to think about regarding the new Ficht's - the 225 puts out 238hp at the prop while the 250 puts out 249. Although pricewise there isn't much difference, you might want to go with a 225 since the power gain with a 250 is marginal, plus it will probably consume more fuel.
My vote is for the Ficht (or HPDI for that matter) over the 4-stroke for exactly the same reasons Jon G mentions.
