Shark Bait Posted July 10, 2007 Share Posted July 10, 2007 Hi all. Just curious. I've got a 75hp E-tec on my haines hunter 4.5 metre haines half cab. I filled my tank up at the Brooklyn mariner headed down the river to windsor. Sat on 3500rpm at 42kph (read by GPS) and 108km later, I was at Windsor. I pulled the boat out of the water & filled it up at the service station. It took 29.75 litres to overflow the tank. The boat had me, food & supplies for a couple of days & my fishing gear on board. The water was dead flat all the way. 108km travelled at 3500rpm at 42km/h on 29.75 litres. How does this compare to your fuel costs? Rick. Link to comment Share on other sites More sharing options...
a boat Posted July 10, 2007 Share Posted July 10, 2007 Hi Rick, good informative post. That would of been a nice day, I have done that a few times myself, sometimes at a bit higher speed than 42KPH, but it is a good run espcially from Spencer upwards. I work this out to be 12L/Hr and that is pretty much what we are seeing with the 75/90HP E-TEC. In my humble opinion that is pretty good fuel economy for an outboard. Cheers, Huey.

fishingrod Posted July 10, 2007 Share Posted July 10, 2007 Best economy ive ever done is with a 80hp Yammy 4 stroke (carby) pushing a Southwind UB longboat running at around 4000-4400 rpm Brooklyn To a little past Sackville Ferry And back to Brooklyn again Around 80 litres. That included idling around changing spots etc up near Sackville. (sorry i never added up the distance) Im sure we all have horror stories of huge fuel use in bigger boats ! but this sounded like a green economy thread:) cheers Rod Link to comment Share on other sites More sharing options...

wise one Posted July 10, 2007 Share Posted July 10, 2007 My DeepV 260 with Volvo D4 inboard diesel and duoprop leg delivers approx 1 litre per nautical mile regardless of speed. At 10 knots, I'm burning 10 litres per hour, at 20 knots - 20 litres. Link to comment Share on other sites More sharing options...
TheDiko Posted July 10, 2007 Share Posted July 10, 2007 My DeepV 260 with Volvo D4 inboard diesel and duoprop leg delivers approx 1 litre per nautical mile regardless of speed. At 10 knots, I'm burning 10 litres per hour, at 20 knots - 20 litres. I'd love it if my boat did the same as that. For a trip out to Brown's and back in a 6m Haines Hunter with 150hp Evinrude Ocean Pro 1996 We can get away with 55L - 65L if the majority (70km or more out of 120km) is travelling at 1800 to 2100 rpm. Other than that it uses approx 1L/km at 4000rpm IFS Link to comment Share on other sites More sharing options...
Flightmanager Posted July 10, 2007 Share Posted July 10, 2007 I have a 75 Etec , average fuel consumption is 2NM per liter . This is on a 4.3 M Haines Hunter runabout ( fibreglass). Wherever possible , I run it at full noise , but most of the engines running time is spent at 3000-4000 RPM , which gives an indicated speed of between 25 and 35 MPH. This is with 2 adults , big esky , fishing gear etc. A 25 litre tank will give me 85KM , or 3.4KM/L . Ross Link to comment Share on other sites More sharing options...

domza Posted July 10, 2007 Share Posted July 10, 2007 85hp mercury 2 stroke, a day trip around the bay (40 or so kilometres) 15-20 litres depending on the weather and my mood. Link to comment Share on other sites More sharing options...
james1990 Posted July 10, 2007 Share Posted July 10, 2007 Well the old haines hunter 580slf with twiwn 90 yammy 2 strokes trolling for about 6 hours sitting between 6.5-7.5 knots th whole time, alternating between each motor we used a staggering 110liters of fuel. That was motoring from cooks river ramp- mol point- close fad trolling from close fad to about 7 miles off south head(botany) then back to close fad then home. Really heavy drinker The new rig with a 150hp yammy 4stk uses 4 liters an hour at various rpm's/speeds (under run in time), but once run in time is over i will be able to give you a better idea on how much fuel it uses (hopefully beter thn 4 liters) cheers james Link to comment Share on other sites More sharing options...

I nearly bought the yamaha 60 4 stroke, but mechanics scare the crap out of me. I settled on the 75 E-tec, 40kg heavier & 2 grand dearer then the yamaha, but no dealer maintenance till it's out of warranty. Suits me. Link to comment Share on other sites More sharing options...
