Da way we do it! - -> Old School Stuff!!
1977 7.5 Kohler Gasoline Generator
Fuel Consumption (as per orig factory book):
1. 25% Load .70 gal/hr (2.6 lts/hr)
2. 50% Load .80 gal/hr (3.0 lts/hr)
3. 75% Load .1.1 gal/hr (4.2 lts/hr)
4. 100% Load .1.4 gal/hr (5.3 lts/hr)
We generally use our Kohler gen set .50 to .75 hr in morning and sometimes (but not always) for approx same duration in eve. Generator is well muffled, runs smoothly, and creates no vibration as well as very little noise either aboard of nearby off board. I keep the load between 25% and 75% (often lower than higher; as I don't activate all breakers at same time). I can therefore safely calc my gasoline use at 1 gal/hr. Figuring 1.5 hr daily run time (that’s a bit higher figure than actual use): 4 day weekend = 6 gallons gen set fuel per weekend. Not too bad for coffee, hot water, ac fridge chilled, house bank charged, some limited cooking (I do a lot of BBQen) and computers charged while playing aboard and swimming off our fun Tollycraft tri cabin!
