Fuel consumption figures for Mercruiser marine engines:
3.0 L: 6gph at 3500 cruise, 11.5 gph WOT 4.3 L (2 bbl): 8.5 gph at 3500 cruise, 16.7 gph WOT 4.3 L MPI: 9.0 gph at 3500 cruise, 19.5 gph WOT 5.0L (2 bbl): 9.0 gph at 3000 (not 3500) cruise, 20.5gph WOT 5.0 L MPI: 10.9 gph at 3500 cruise, 22 gph WOT 350 Mag MPI: 12gph at 3500 cruise, 22gph at (5000 rpm) WOT MX 6.2L MPI: 13.2 gph at 3500 cruise, 25.1 gph at 5200 WOT 496 Magnum: 16.0 gph at 3500 cruise, 30.5 gph at WOT 496 Magnum HO: 18.5 at 3500 cruise, 33gph at 5000 WOT. Hmm, lets see: Running a pair of 496 HO gassers at well above cruise speed would likely burn close to 30 gph per side or 60gph total. 60 gph X $5/gal = $300 per hour in fuel costs. Over $2000 for an all-day high speed run. Running the same engines at 3500 rpm cruise would burn 37 gph, for a total of $185 per hour in fuel costs at $5 a gallon. Still not cheap by any stretch of the imagination, but at least not as far out of the questiong for most folks as a $2000 daily (or even weekend) fuel bill would be. |

Here's a typical day at the lake. - This does not include the monthly
payment, maintenance, insurance or possible repairs needed after the trip on either the boat or the tow vehicle, only the expense for the day. If we're on the lake for about 8 hours and cruise (~35-40 mph) about 25% of the time and approximately 10% of the time we're running wot to pull a skier or towable and the other 65% the engine was off and we're relaxing or swimming, we would burn about 35 gallons of gas. That will cost us about $112. And I used to think the beer and ice was the big expense. (8 x .25)9.0=18 x $3.25 = $58.50 (8 x .10)20.5=16.4 x $3.25 = $53.30 34.4 gph 111.80 Park entrance fee 7.00 Food/beverage/ice 38.00 TOTAL= $156.80 Fuel consumption figures for Mercruiser marine engines: 3.0 L: 6gph at 3500 cruise, 11.5 gph WOT 4.3 L (2 bbl): 8.5 gph at 3500 cruise, 16.7 gph WOT 4.3 L MPI: 9.0 gph at 3500 cruise, 19.5 gph WOT ----- 5.0L (2 bbl): 9.0 gph at 3000 cruise, 20.5gph WOT ----- My category 5.0 L MPI: 10.9 gph at 3500 cruise, 22 gph WOT 350 Mag MPI: 12gph at 3500 cruise, 22gph at (5000 rpm) WOT MX 6.2L MPI: 13.2 gph at 3500 cruise, 25.1 gph at 5200 WOT 496 Magnum: 16.0 gph at 3500 cruise, 30.5 gph at WOT 496 Magnum HO: 18.5 at 3500 cruise, 33gph at 5000 WOT. |

Where did you find that info, and why isn't the 5.7L included? -- The 5.7 isn't included because it hasn't been a current offering in the lineup for some time now, other than in the 350 mag version. The 5.0 has replaced the 5.7 as the standard small block V8 offering. Go figure. |

You did have to remind me of that. We live about 30 minutes from the
lake which burns about 15 gallons round trip, so add another $48 to that total. Yikes! a $200 day. |

Typically for a day trip we go to lake pleasant, it's close enough for
us to go afterwork on a weekday or first thing on a Saturday morning for a breakfast cruise. If we're going for a few days or more we'll head to Lake Mead or Lake Powell. |

Our 21 foot runabout is powered by a single 190 HP 4.3L Volvo Penta I/O. We normally cruise at about 3200 rpm, although we may run it up a bit to catch up with some friends on the Lake or to get somewhere.......fast. This boat cruises at 35 mph and will do close to 50 mph WOT. Most of our high fuel consumption comes when we pull the kids skiing or tubing. As we only purchased this boat late last summer I have not had the chance to develop any GPH estimates when cruising vs. pulling our kids on skis or in tubes....but the bottom line for us is that the fuel price increases will not be a problem or impact our new boating habits. I am certainly glad we sold our 32 footer with twin 260HP engines. ;-) |

Runnone *one* 496 HO gas engine in a boat is an acceptable definition of stupidity. If your is heavy enough to need a pair, then you should have gone diesel. Harry, that might be alright for a cruiser or trawler, but the speedboat crowd. I don't think the Donzi, Cigarette, and Baja crowd will go for it. And if you can afford the $225,000 for the boat, then fuel economy is probably the last on your mind.... |

For what we do, it's really not bad by the standards of the day. $30. for fuel for my old '89 mercury to tow my 18' Chris Craft to the lake and back 120 mi. round trip Cruise and putter around the lake for a day. with a 3.0 GM running 3200 rpm, and that will pull about 5-7 gal. Another $21.00. I look at it like this. My family can have a decent day on Lthe lake, OR I can load up the car and take them to 6-Flags St. louis. and pay 40 bucks a pop to get in and eat their $4.00 hotdogs and $2.50 soda pop and stand in a hot line for 45 min, to ride some whirlie-gig for about 3 minutes. By the time we get home we's spent $300.00 and wonder ..."why?" The lake is proven to be the better choice. We get to do what we want to do, and enjoy the water. More fun, practical, and economical! |

New boats in the 33+ foot range generally will cost that and more..................many (most?) take out loans to afford them. These boats hold 200+ gallons of fuel and are not fuel efficient. A $1 to $2 jump in fuel prices will certainly change their boating habits. ;-) |

Chuck,
Where did you get your fuel consumption numbers? They are a bit on the low side in my experience. The normal rule of thumb for gas engines, which I've found to be pretty close, is 1 gph for every 10 hp. At 3400 RPM most engines, properly propped for the boat, will run at about 50% of maximum rated power. That would put the 350MPI at 15 gph and the 496 HO at 21 or 22. I have neighbors with both engines and that's in the ballpark for what they are seeing. My old 350 4bbl rated at 260 hp has always burned right around 13 gph at 3400 cruise. |

Do you have the inflatable/dingey setup on your boat on the starboard side of the aft cabin? Mrs.E. has me on a mission to find one that fits the existing holder (davits?) .... I don't know what you call it. She wants something with a small outboard. Any recommendations? RCE |

Yes, our dinghy is on the starboard side of the aft cabin. It is an 11
ft Caribe RIB with a 15 hp Merc which rides and performs well for a boat of that size. It would be too much weight without a hoist however. We use our mast and boom as a cargo crane but have extra reinforcing stays on the mast, in addition to an electric hoisting winch, and multi part block and tackle on the boom lift. Unless you have an electric or hydraulic hoist, you really need to stick with something that is light and easy to handle. A small, soft bottom Avon with something like a 3 hp OB would fit that description but not perform particularly well except for short harbor hops. |

Can you accept attachments at your hotmail address? If so, I'll scan
the page and email it to you. Yes, attachments are no problem. My 350 burns about 9 gph at 3000 RPMs also. Probably it is running on only 2 bbls at that speed. |
