I don't get it. I went on the EIA site (govent site for gas prices) The average price of GAS last week in L.A. was $3.02...the average price for diesel $3.14.!! Also, the cost difference on a brand new Sea Ray, gas vs. diesel engines was less then 10k. So, what's the big deal? If I can buy a used 390 gas vs. 390 DIESEL with the same gear for 50k LESS, WHY AM I NOT BUYING A GAS BOAT? Diesel can't be THAT much more efficient (smell aside) to offset the Hugh price difference..or can it? If, (generally speaking) I'm burning about a gallon a minute in gas am I burning two gallons a minute in diesel? Where's my logic flawed?
