Seems 175 - 200 is the size to have. My 175 pushes my dually plenty fast. I've seen some folks with single v-4's - that I don't understand. Way to underpowered for me. I'm sure you'll come across a used carbed Yammy for cheap $$. The 250 will drink the gas if you open her up and insurance will be a problem if you go that route. I say hold out for the right size motor (but $600 isn't bad to get you back on the water quick)

just my .02
