What Mileage does your starflight/liner get??

[Needafunboat]

OK, well I realize that this is a little bit like the guy driving an H2 whining at the pump but I think (hope) there may be something wrong.

This weekend was the first real trip out in the starliner. On Sat, I ran a 23P aluminum prop that was ventilating BADLY on and blew through about 19gal in what I'd guess couldn't have been much more than 40 miles - much of it easy crusing. I did have a few top speed runs on there too. My buddy's 4winns 190 horizon (4.3L EFI I/O and a HEAVY boat) who followed me for about 30 of those miles didn't move much off of the Full mark!

On Sunday, I put the 26P trophy on and the ventilation was basically gone. It actually ended up coming out of the hole better with the 23P! We did probably 30 miles but I still think I went through about 10 gallons during all easy cruising, which seems just a bit much to me.

I'm wondering if this is normal consumption for a starliner w/ a 225 EFI (3.0L - not a DI motor), or if maybe the engine isn't running right. It feels strong and ran 64mph(gps) @ 5400rpm. So power output sounds about right. Compression is good on the motor too.

Let me know what type of rough mileage you guys get. I realized it all depends on speed and how hard you hammer it - but I'm just looking for some general info.

Thanks,
Anthony

I get about 8MPG (when it's behind the H2)...seriously, I think you are about right with the 30 miles and 10 gallons. I have a '92 with a 2.5 xri. fuel injecrion. I always figured roughly that I get around 3-4 Miles per gallon. Less when it's full tilt. I do know this...I have a 200 optimax on a fishing boat and the opti gets a lot better mileage. Good luck with your rig...Tom

At 35 MPH cruise I get 4 MPG with my 200 EFI. AT WOT I would be looking at 3 MPG. The EFI's are harder on fuel than the carb motors. When you clock your distance on GPS you might be surprised how far you traveled. I doubt you are only getting 2 MPG.

My 200gt is a gas guzzling pig,I was beating on it for about and hour on Sat and sucked down 15 gal...
I was out last sat for about 3hrs cracked it open a few times and did some cruising and burned about 12 gal..
I can get a whole day out if I am gentle and have fuel left over for the next day,,but once you crack it open,say bye bye to your fuel..

clean injectors are very important for performance and fuel milage. run some seafoam in it a for a couple of tanks, than about every 3rd tank.

Thanks guys - OK, so the motor is running basically right. I will take curt's advice and run some seafoam through it.

I had the GPS on, but never clicked the timer to accumulate the distance (duhhh...).

I guess the thing that strikes me is how my buddy's big, heavy 4 winns gets SO much better mileage. He was running similar speeds as me and didn't go through nearly the gas. I know stingray advertises their 19.5 BR w/ the 4.3L EFI would get 6mph at 30mph. The 4 winns is a bit heavier / deeper boat with that same motor so I'd say the best he was getting is 5mpg.

Then again, my gas gage is skewed one way (reads empty when there is 10 gallons in it). His reads full for the first half tank and then drops like a rock.

So he was bragging about only using 1/2 tank, but I probably didn't use THAT much more than he did, and I had about 10 more miles, a couple of high speed runs in there plus the ventilation issue.

On the upside - the boat ran and handled GREAT. Big enough for 2 families (and my mother and father-in-law for a while), tons of power, nice ride even when the lake kicked up a bit. All around awesome boat. I can also say that I will always own a boat with swim platform(s). THe kids had a ball climbing up and sitting on them. Plus I can change a prop in the middle of the lake!


Any other numbers out there??
