EFI, DFI, or Carborated for 2-stroke?

[johnk86]

Trying to get opinions on which is best for reliability, cost of repairs, and cost of maintenance. Keep in mind that I'm a limited "do-it-yourselfer" (e.g. haven't tackled rebuilding carbs, adjusting linkages and timing scare me somewhat). Also the engine may sit for three to four months at a time without usage. I looked at the "smiley" chart on the iBoats outboard page, but don't understand the reasoning behind the "smilies".<br /><br />PS: The engine would be 175hp to 225hp.

Carbureted 2-strokes are the easiest for the do-it-yourselfer. Not a whole lot you can do yourself on a DFI. EFIs are somewhere inbetween.<br /><br />Reliability is about the same as long as the motor is well maintained.<br /><br />Carbureted 2-strokes are the least fuel efficient, EFIs aren't much better. DFIs are best, even a bit better than 4-strokes in most regards. Regardless of the induction, it still takes about the same amount of fuel to get the same WOT horsepower. Efficiencies vary more at lower RPMs.<br /><br />Carbureted 2-strokes are banned on some waterways (not many, but it'll get worse rather than better).<br /><br />There's some general information for you. Your specific needs might help in providing more appropriate information.<br /><br />Smileys are for whatever you want to use them for:<br />Good Grief! <br />Ha Ha! <br />Sarcasm <br />Cool! <br />What in the world??? <br />Oh my! <br />Grrr! <br />etc.<br /><br />Click on the smiley and it'll show where the next typed character would go.
