Some interesting fuel consumption figures....
Hats off to a gutsy move by a major division of Brunswick. Once again
their annual product brochure frankly addresses a subject that most builders would rather ignore and more than a few salespeople have sugar coated over the years: Fuel consumption. The 2007 versions of the engines used in their medium size cruisers (36-48 feet) are reported thusly: Cummins QSB 5.9 375HP configuration: Propshaft HP 364, WOT 3000, Cruise 2800. GPH at WOT 19.9, GPH at cruise 15.6 Cummins QSB 5.9 420HP configuration: Propshaft HP 407, WOT 3000, Cruise 2800. GPH at WOT 23.1, GPH at cruise 18. Cummins QSC8.3 493HP configuration: Propshaft HP 478, WOT 2600, Cruise 2600. GPH at WOT 26.6, GPH at cruise 20.3 Cummins QSC 8.3 533HP configuration: Propshaft HP 517, WOT 2600, Cruise 2400. GPH at WOT 29.0, GPH at cruise 22.2 Cummins QSM11 660 HP configuration: Propshat HP 640, WOT 2300, Cruise 2100. GPH at WOT 33.3, GPH at cruise 23.7 For gasoline engines: Mercruiser 8.1S Horizon: Propshaft HP 370, WOT 4200-4600, Cruise 3250. GPH WOT 29.5, GPH at cruise 16.0 Mercruiser 8.1S HO: Propshaft HP 420, WOT 4400-4800, Cruise 3500. GPH WOT 33, GPH at cruise 18.5 Note: when I posted the version of this same info for either the 2005 or 2006 models several people who don't own any of these engines (and had no actual technical frame of reference of any sort) all chimed in to claim I was full of schlitz. Be aware that I am only passing along some published information and not attempting to claim that I have personally validated any of it. This information is presented as possible fodder for discussion, not to facilitate a flame war. |

Not me, those numbers are very closely aligned with the prevailing rules of thumb: 1 gph for every 10 hp gas, and 1 gph for every 20 hp diesel. This assumes that rated hp is developed at WOT, and cruising hp is related to the square of RPMs, e.g., 70 % of WOT = 49% of peak hp. It is important to note that your numbers are "per engine". |

It is important to note that your numbers are "per engine". Indeed. And all of this manufacturer's designs in the 36-48 foot category are twin engines. With consumption on a pair of the larger engines in the general range of 50-60 GPH and facing the almost certain prospect of another summer of $4.50- $5.00 fuel dock prices fuel consumption becomes a major consideration. The old saw that fuel is so relatively inexpensive compared to the other aspects of boat ownership that it shouldn't be a major consideration is a lot less accurate than it once was. |

Depends on how you use the boat of course. If you're doing long distance cruising it's very important, sitting at the dock as a party boat, not so much. We've already done almost 1,000 miles this year and will probably add another 3 or 4K by end of year. Even trawlers get expensive at that rate. |

OUTBOARDS RULE!!!! :) You know what's kind of interesting (not trying to get into the great relative value debate) to me? I'll bet I've seen at least 11 boats for sale on lawns that I've not seen before. And they are all in the smallish, inboard gas powered 24/28 foot category type boats - lot of Bayliners, one or two Stamas and one with twin 454 Crusaders. Being nosey as I am, I've stopped a couple of places and the common issue seems to be gas milage on boats. As in can't afford to run them. |

Perhaps you should subscribe to a source of information about boating in the Northwest rather than making pronouncements showing your lack of knowledge thereof. Here, this may help: Nor'westing Magazine 513 Bay St. #7 Port Orchard, WA 98366 Phone: 360-874-1992 Fax: 360-874-1987 Write them a letter, maybe they'll send you a copy. -- ***** Hope your day is better than decent! ***** John H |

Our one-day summer would coincide nicely with your annual usage of the Yo-Ho. |

It looks like higher fuel prices are here to stay, and one of the more heinous consequences is going to be the redefinition of most powerboating as an elitist activity. Wally and Wilma Sacklunch work pretty hard. She's on her feet all day as a cashier at a local drugstore, and he drives a local bakery truck. It's all they can do to bring home enough to make the mortgage payments, keep up the notes on their F250 and Plymouth Voyager, feed three kids, and stay close to current with the utility companies. They had always dreamed of having a boat, and spending some quality family time fishing, water skiing, beach camping, etc. A few years ago, they refinanced their house, bought an older 25-foot express cruiser and paid off their credit cards. Now the credit card balances have once again risen to their previous highs, the house has stagnated or slumped in value and can no longer serve as an ATM, and the boat has to sit unused because it costs $800 to fuel it up for an active weekend. That fictional couple represents a wide swath of the American working class. While boating isn't supposed to be inexpensive, it's a shame when owning even a humble boat becomes an impossible dream for people who work so hard to earn a living. It's easy enough to drive by all those boats for sale on the front lawns of neighborhoods across the country and think, "They should have made better choices." That's certainly one valid way to look at it. By the same token, it's a shame that through no fault of their own the economic dynamics shifted and left them without any reasonable options. It's easy enough to blame the oil companies and politicians (from both parties) for the fact that boating is getting farther out of sight as a recreational option for many families, but the boating industry has to bear a large share of blame as well. It seems like every single boat builder is chasing the same narrow spectrum of the market. Nobody even thinks it's unusual when a new 30-foot powerboat sells for as much as a new 3000 sq foot house in a decent or better neighborhood- and that (IMO) represents a problem. By the time most of these boats depreciate enough to be affordable by ordinary working class Americans they're far too expensive to maintain (or, in many cases, fuel). |

When I was a kid, folks like that owned 14 ft runabouts with a 35 hp outboard, if they owned a boat at all. They'd run all afternoon on 6 to 12 gallons of gas, costing about $4. Engineers and managers owned 20 footers; doctors, lawyers and business owners, 30 to 35 feet. If you were chairman of the board of a sizable corporation, maybe a 45 or 60 footer. The problem is that expectations have changed. |
