I am not sure how you sell a 400 pound 50 HP motor. What kind of boat does this go on? Maybe some kind of small, displacement hull trawler or something I am talking about a real fishing boat not a recreational "trawler" like you have, a boat dragging a big net. It might also be useful on a "pusher" boat like they use to move work barges around. Houseboats -- x ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

Over on the real boat board, people were pointing out that a 2 cyl 4 stroke will be a rough idling sommich. Did you see the exploded view of the dual crankshaft design? "The benefits of the engine design are many, most significantly that the two-counter-rotating crankshafts offer perfect primary balance of the engine and a smoothness normally associated with six-cylinder petrol engines, not two-cylinder engines of any type, and particularly not diesel engines. With a lack of vibration inherent in the design, a Neander engine does not need the weighty vibration-absorbing robustness of a traditional diesel." |

When we bought Mrs.E.'s 1984 Grand Banks I was a little concerned because it had over 7,000 hours on the little Ford Lehman 120 hp diesel and I mentioned my concern to the mechanic who did the pre-purchase inspection. He told me not to worry ... it was just about broken in. |

If gasoline is three bucks a gallon, the conversion would cover 25,000 gallons of gasoline. Ouch. 😀 THere's something about gas engines running for hours at 3,600 to 4,000 RPM that disturbs me, even though I realize they have cams, etc., that are designed for it. Seem to remember the general rule was 1,000 to 1,500 hours before a rebuild. I have the same problem with land yachts. Had a large Pace Arrow motorhome with a big ass gas engine that I thought would explode climbing the hills out on Rt. 84, heading for Florida. At a certain size/weight diesel is the only way to fly. |

The guy around the corner has a 36 (Donzi I think) with 2 250s on it that will cruise in the 30s burning a combined 25-30 GPH or so (a whole lot more at WOT tho) |

If gasoline is three bucks a gallon, the conversion would cover 25,000 gallons of gasoline. Ouch. ? Realistically you would be trading the whole boat or just buying diesel power in the first place so the difference would be less. I wonder what the difference is on a new boat powered each way. I suppose it is a pay me now or pay me later thing. Might be hard to compare. A boat of the size and weight that justifies a diesel probably isn't (or shouldn't be) available in gas. I know of two people who did gas to diesel conversions. The first was an old, early 80's vintage Hatteras (36 footer) that originally had gas engines. They were replaced many years ago with a pair of DD 6-71's and that boat is still going strong. (Justin: "My Way"). The only problem is that the added weight causes it to "squat" and it really doesn't run well on a plane. But, an old Hat is a very heavy boat. The other conversion was on a 27 or 28 foot Blackfin. The guy who owned it was big time into fishing and when the gas engines required a rebuild he replaced them with diesels. I remember when he relaunched and arrived at his slip in Scituate. The boat sat noticeably much lower in the water. (Justan: You know him also ... I forgot his name but he used to run the shark tournaments at Oak Bluffs). There was another guy named Carl who also had a similar, but gas powered Blackfin on the same dock.) Fun times back then. |

I suppose it is a pay me now or pay me later thing. I'm not sure if my numbers are right, but some years ago, five at least, maybe more, Parker was thinking of bringing out a larger cruiser with a 300 hp Yanmar on a jackshaft and actually built a prototype that I got a ride in at the local dealer's. The price differential between it and a pair of 250 outboards was about $30,000 or so. The outboards were about $25,000 for the pair. For reasons unknown to me, Parker never put the boat into production. I might have been interested back then if it had a straight diesel, but the jackshaft was hooked up to an I/O type drive. The jackshaft was really noisy. But the more centered placement of the diesel made a smooth-riding boat in really rough water. |

It would do 25 kts wide open with half fuel but I was concientious about keeping the RPMs at no more than 3200 or 3300. The whole point of my comparison excercise was to show that increased fuel range with diesel is often the deciding factor as opposed to fuel cost savings. --- This email has been checked for viruses by AVG. http://www.avg.com |

Oh, I agree with you, and on a 30+ footer, one or two diesels usually are a better choice, especially on a heavier boat |

Once the Japs showed us you can make a better engine, all of them will run many thousands of hours. My Yamamerc 60 had over 3000 on it with no indication it was in need of anything. I got rid of it because of all of the other $200-500 screw on parts that were nearing end of life. |
