Default Improving Gas Mileage

Our 3000 SCR has twin 5.7L EFI's and wanted to ask what can be done, if anything, to the engines to improve mileage? Or what can be done to the boat in general?

make sure you keep the weight down...sometimes boats gain weight over the yr and need to have things taken off if not needed....run with empty water and san-tanks (ie waste tank)
run at the most effeciently trimmed out speed...so...if your boat runs best at say 23 knots and it starts really plowing at 19...pick it up until your forced to slow down....so...my point is ..run in the best water possible...the best speed your boat will run at and trimmed properly....one thing that will help is a fuel flow meter ....tells exactly how much fuel your using.....
make sure the drive and hull is clean and free of barnicles...scum...etc...

one last thought.....it's a boat.....your going to get crappy mileage no matter what you do...but you can do things to lower the usage per hr....

I always get a better 'burn rate' when I remember to lift the swim ladder. I did start running a fuel additive and have seen some increase. I'll try to post the background data.

I use a product called XLP. It is developed with Chevron support (now there's an oxymoron: Chevron and fuel savings?)

Treatment is 1.5 oz per 15 gallons (US). Comes in a 16 oz bottle (treats about 160 gallons). Cost is $14.49 each.

It's available at www.dtmax.mychoices.biz just type in gasoline or diesel in the search window.

They are listed as each, you get free shipping when you order a case (6 each)

Send me a PM (personal message) with your email and I will send the source document of what it is and how it's used.
