With modern common rail diesels, there is almost no soot, and very small amounts of carbon monoxide. On a percentage basis on board gas generators rank right at the top for accidental deaths aboard. 3.5 kw diesel generator would weigh about 160 lbs, separate tank would be no problem at all, and the whole package really not much heavier than a gas alternative. However the only reason for a generator is for air conditioning which would be mandatory in my market on a boat this size. The Volvo drives are COMPOSITE hence no corrosion problem. However if you have aluminum outdrives you can install a cathode protection system. The newer drives will usually clear the water when tilted up. I agree that once loaded the gas outboards are going to struggle. As far as diesel putting it out of reach, at $300K for a 34 ft. boat I don't think the cost difference would really make that big of a difference to the demographic.
