Gary, it sounds like you haven't been on a boat with common rail diesels, there is almost no smell or soot, next chance you get do yourself a favor and hitch a ride on one with them, your Yanmars unless they are new, are not common rail technology. When I said noxious fumes I was doing it tongue in cheek, diesel has a lot more sulphur dioxide that's why the smell vs. gas, but again much less with common rail. Bob, of course with the exhaust hose off, on an older diesel you are going to have lots of smoke and fumes we are talking about normal operating conditions. Also where is diesel twice the cost of gas?

REPLY In most places in BC gasoline (bottom grade 87 octane rating) is $1.25 - $1.27 per liter. Diesel is about 10 cents more per liter. That's $5.62 per imperial gallon for gasoline and diesel cost $6.08 per imperial gallon. We have been told the reason diesel is so much more expensive is because it's now low sulphur and cost more to refine. Yeah sure! Mostly its taxes! But it doesn't smell of sulphur any more. Arild
