Re-power question ,, as to engine etc
I may, or may not repower my boat. But, if I was to, where would one start
in a search for a new small diesel to repower a sailboat? Is there a trick to finding a deal? Boat shows? I seem to remember someone here mentioning boat show specials. I am going to keep my eyes open for a small ( 16-20 hp ) diesel . If I see a good deal, snatch it up. Then take my time putting in in after taking out the old. But, where to keep those eyes looking .. that is the question. |

Get to know your local dealers and keep an eye on EBAY also. |

Otherwise, see if your boat had a drop-in diesel when it was built and concentrate on that series, as making up a proper new bed is either no fun or very expensive. A modern diesel would require replacing just about everything, which jacks up the price. We repowered with a Yanmar over a decade and LOVE it, but if we knew what we know now, I'd have gotten a rebuilt Volvo MD and new prop, saving a bunch of B.O.A.T. bucks. -- Jere Lull Xan-a-Deux ('73 Tanzer 28 #4 out of Tolchester, MD) Xan's Pages: http://members.dca.net/jerelull/X-Main.html Our BVI FAQs (290+ pics) http://homepage.mac.com/jerelull/BVI/ |

At 20 HP, you're in the "Atomic 4 Replacemnt" group, which is well
populated. Several manufacturers offer 'Atomic 4 Replacement' diesel engines. Many are based on the same Kubota 3 cylinder block, the only difference being the 'marinization' of the engine. Yanmar has a similar size / weight engine which is not based on Kubota - it's a Yanmar (!), the Vetus is a Mitsubishi, and I believe the Volvo is a Perkins Here's the list: Universal M3-20B Phasor Marine P3-20-SM Beta Marine BD722 Yanmar 3YM20 Westerbeke 20B2 or 30B3 Vetus M 3.09 Volvo D1-20 I saw this engine at the Annapolis show, and it has some nice features Lombardini LDW 702 M If weight is a concern, the first 3 (the Kubota derivatives) and the Lombardini have a 'dry' weight of around 230 lbs. The last four are closer to 290 lbs. The Volvo is slower turning (3200 RPM vs 3600 for the rest) *and* comes standard with a whopping 115 Amp alternator. The cost of the basic engine + standard gear reduction (less high-end meter/light panel or other options) is *around* 5.8 - 8.5K$US. Often the best deals are had at boat shows, so if you're looking to save $, enquire at a major show. This price does *not* include installation; you get the engine on a wooden pallet. MW |

Boat shows are good for maybe 7 to 10% discount. If you want to save some
big bucks find an industrial dealer for the brand you are interested in. The lowest price I found for my Yanmar 4JH4 from all the "marine" repowering companies authorized to sell in Georgia was $12,100 plus "delivery costs" of $450 and shipping. At the Miami boat show the dealer wanted 11,200 plus delivery costs of $400 and shipping. Accidentally working from an industrial dealer list on the Yanmar site I contacted W.W.Williams in Atlanta. They sell industrial tractor and stationary engines but through their Savannah office ordered me one for $9,500 and took AMEX so I got 9500 frequent flyer points as a bonus. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Then take my time putting in in after taking out the old. A different make of engine usually means a new engine bed, perhaps re-alignment of the shaft exit, almost certainly a new gearbox, re-machined shaft and propeller. Controls and wiring also need to be considered. These jobs will add up to a good percentage of your costs, so it's worth considering a re-build of your existing engine as one option. If you're convinced of the need for change, then start narrowing down the engines you'd consider by checking out all the factors above, looking for the maximum consistency and easy adaptations. So, starting point - what will fit? Next, what will fit with less effort? Then, get down to the search, bearing in mind the cost of all those alterations . . . deals are unlikely to offset those! -- JimB http://www.jimbaerselman.f2s.com/ Comparing cruise areas within Greece and N Spain |
Re-power question ,, as to engine etc
I've heard nothing but good things about the Yanmars, aside from cost, and
my experience with ours certainly bears them out. At 27 years of age it feels like one of the sweetest running pieces of machinery I've been associated with. I certainly trust it a lot more than the engine I used to fly behind:) It would be worth having some prop calculations performed. There is no point in putting in a 3 cylinder Yanmar (or other engine) if your prop can only use the horsepower of 2. The 3 cylinder will be a bit smoother but the 2 cylinder, 2 blade, installation in our boat is plenty smooth. Diesels, especially Yanmars which are a cool running engine, will give more trouble running too lightly than at their rated continuous horsepower. After you've paid for a cylinder you don't need, you then have the reduced maintenance clearance and extra weight for life. The power requirements of your Bristol should not be very different than Strider and I have all the power I need. I was able to keep moving straight into the wind during a squall that heeled us under bare poles to our normal sailing angle. The sail cover was thundering and the rain hitting my face stung. I don't think you need much more power than that unless you plan to tow a barge. -- Roger Long |

Re-power question ,, as to engine etc
Roger ,, you have a 2cyl, 2 blade? Very interesting. What is the hp of the
2cyl? The reason I ask: I got to looking at engines on the net. Always looking, looking, looking.. anyway,, one thing led to another and I started looking at the BETA engines. BETA has a new diesel which is a 16hp, 2cyl. I'm not sure what the blade requirement is. I've always felt that many boats overpower. That isn't a bad thing if that is what one wants but for just getting in and out ... that 16hp, 2cyl sure did look pretty. Fits the same general area, bed as my Atomic 4. I love the Atomic 4. It is so simple. And with help like Mr Moyer in MD the engine will be around forever. That said: having gallons of gasoline not far from where I am cooking, sleeping, etc does get my attention. I am not in a rush. This is not an emergency or anything. I just figured I'd look, learn, and if a really great deal came along .. buy. Tell me/us more about what engine you have in your boat. What size? HP? Alternator? All the good stuff. ======== "Roger Long" wrote in message ...
