Well Casey if these were EFIs I would tell you not to worry about the fuel burn, shoot it's only money and the Government can just add more taxes to help you pay for the fuel!!
However the Optis are much better on fuel burn and that might be a really nice combo especially with the lighter weight issue of the two strokes. Not sure what the price is but low hours sure makes it a sweet deal. Again my '03 225 EFI treated me very well except at the gas pump!! Good luck!
