1:54 PMKeyser Soze - show quoted text - Mercury Marine and several others have high horsepower diesel outboards under development and maybe in production or close to it. I saw a model claiming 200 hp a couple of years ago at a boat show...don't remember the brand name, ?X something or other? ... Oxe(?) http://www.mby.com/gear/oxe-200hp-di...e-tested-51194 With all the nice 1.7L diesels in non American cars, should be easy to design a nice diesel outboard. I think the large Honda is an automotive engine, dry slumped and on end. |

According to the article is also costs twice what a 200hp Yamaha 4 stroke goes for. Ouch! |

Diesels 'usually' last Ingersoll than a gas job and are much more economical on fuel. But what you save in fuel costs probably don't over ride the massive up front expense of the whole unit. Bad trade off IMO. |

Bad trade off IMO. They said the main market was military and commercial, with some tenders for yachts where price was no issue but fuel compatibility was. It wouldn't make sense for pleasure boating. |

Diesels 'usually' last Ingersoll than a gas job and are much more economical on fuel." How auto check thought that "Ingersoll " would be a good substitute for "longer" is beyond me...🙄 |

Bad trade off IMO. === Increased range because of greater fuel economy is the most common reason for justifying the higher cost. Diesels use almost 50% less fuel for the same power output, and have higher low end torque. --- This email has been checked for viruses by AVG. http://www.avg.com |

Bad trade off IMO. === Increased range because of greater fuel economy is the most common reason for justifying the higher cost. Diesels use almost 50% less fuel for the same power output, and have higher low end torque. Which also allows bigger, more efficient props running at lower RPM. I was reading an article somewhere else that said the economy might not make the difference in less than 10,000 hours. They also assume higher maintenance cost, particularly with a belt drive. I am curious how the belt is working out on the 7 Marine. === Here's a real world example of the diesel vs gas engine trade off. Our old Bertram 33 had a 320 gallon fuel tank which seems like a lot but it had 454 gas engines which burned 35 gallons per hour. Cruising speed barely reached 18 knots on a good day. Doing the math, you come up with a safe fuel range of less than 140 miles, not enough for offshore canyon fishing in the NY area. Converting to diesel engines, the burn rate drops to about 20 gallons per hour, and cruising speed climbs to 23 knots or so, for a fuel range of around 300 miles. That's a big difference in the capability of the boat and has nothing to do with the price of fuel or reliability. --- This email has been checked for viruses by AVG. http://www.avg.com |
