Have any of you folks ever quantified the fuel usage of a 350ci EFI,or LT1.If you fill the tank (30-32 gal.)How many hours would you expect to get,skiing 36mph.How much worse would the powerslot be?I once heard someone say that he thinks he uses about a gallon a pass mmmmmmmmmmm whats that about 900 ft?makes it about 6 gallons per/mile.The old i/o uses about 5 gallons per/hour.Just thinking about my first season and pump prices..

At ski speeds, I've heard 12 gallons per hour thrown out as a number. But that math only works for the private lake crowd who either are at idle or skiing. Add a wake boat with ballast into the equation and it gets even more complicated.

My current boat weighs about 2,400 lbs dry, has a 310 hp fuel injected engine and gear reduction. This past weekend, our crew number varied between 3 and 6 people. We made about a 15 minute drive from our lakehouse (on a larger part of the lake) to the river. When we're cruising rather than skiing, we try to keep rpms at about 2,500 or so. Once on the river, on two of the three ocassions, we probably went about 15--20 miles down and then that same distance back. On these two ocassions, I skied five long sets at 32 mph. In four of these sets, we were going against a 4 mph current. All totalled, this amounted to about 30 minutes of skiing or more.

I estimate we used about 23 gallons of fuel. That is to say, we have a 30 gallon tank and we had 1/4 tank left when we got home. The hour meter advanced between 4 and 5 hours. So roughly about 6 gallons per hour for us overall this weekend.

On my 1996 PS 190 with the LT-1 and the slot, I would get 6-6.5 hours of run time per tank when skiing and 3-4 hours of run time when boarding with a full boat and 900# of ballast. Both were at an elevation of 3500 feet above sea level.

I've kept a log of fuel used and hours run over the last 100 hours, in my 2003 197tt. I aways fill the boat in the same spot in my garage and keep a log of any other fuel that goes in between fills. We ski on a river, with about one mile of idling (4 knots) before we get to the ski / wakeboard area. my crew ranges from 4 - 7 people in the boat. My overall average fuel use is 12.06lts/hr, but this has varied between 11.06ltrs/hr and 14.22lts/hr. We ski at 34.2m/hr and board at 20-21m/hr.

Rod;your boat does pretty well on gas if I recall correctly. I keep my fuel receipts for the non road use tax refund. If I can figure out from postings here how many hours I did each year, I can give you a pretty good guess.
