GAS!

[Banks]

Just wondering what kind of gas do you guys use in your boats?

[Ruune]

Diamond Shamrock (Valero), Shell, Exxon, Mobil, H.E.B, Walmart, but never stop & go.

Just kidding- 87 octane is what mines designed for (Merc 350 MAG MPI), so thats what I run.

[Banks]

good thats what i thought i have the same engine. thanks man

[Ruune]

no prob man!

[Dents]

I guess the older 350 Mags are different. Mine is a '98 model and is requires 91 oct. premium.

Hey Banks... I am up in OKC and have been talking to Dom about hooking up and doing some riding. We should all try to get together maybe at Arbuckle sometime this spring or summer. I own a company that manufactures trailer guide pads and some other stuff for dealers all over the country and we make them directly for Tige Boats. It would be good to hook up with some Oklahoma Tige guys!!

[Ruune]

I'll doublecheck the manual when I get home, but I believe it's 87 octane, which mainly depends on compression and valve timing.

[Banks]

yeah mines an 03

Early model Black Scorpions required 91 or better oct. I recommend running mid grade fuel (89 oct), it appears to be a more natural fuel. 87 is old 89 and 91 is souped up 89, they just add chemicals and those chemicals are what leave deposits in your injectors as the fuel sits and gets old(2-3 weeks).

[Domsz06]

87 in mine and it's an 03

[Dents]

I think it is the same for all except the Black Scorpions... it requires a MINIMUM of 87... and states "91 or premium is also acceptable"
so just like in a car that says "regular unleaded".. running premium wouldn't hurt.... I have always run premium in mine since it was new a couple of years ago... in addition, a lot of on lake marina I have been to only sell premium, so I just stick with the good stuff....

[havasu bound]

Who can afford the gas prices right now!!!!!!!!! hahahahaha

[Ruune]

invest in gas cans... I dont EVER buy gas on the water!

[Domsz06]

IS that really true about the 87 just being old 89? I've never heard of that. I was told NOT to burn anything higher in mine then 87 since the other stuff is bad on it. I've never had anything wrong with mine and I run 87

I was just wondering what everyone gets for gallons per hour on there boats per model?

[blr]

I always run premium in my 22ir, never had a problem in 350 hours. hope i wasn;t doing anything wrong. running 87 would be a nice break on the $$.

[Domsz06]

The dealer told me that running anything higher hurts the engine. Not sure if he is right, but ya know. Also, higher occtane breaks down faster so if you don't use it right away it could be a bad thing.

I just called Mercruiser to confirm what we have been talking about on the grade of fuels... they said to ONLY use 87 - and that is what their engines are designed to use(except the Black Scorpion). I (and my wallet) are relieved as now I will be no longer using 91!!!!!

[Banks]

good idea on calling, thanks

[ssrgeoff]

do you think that would be the same on the GM Vortec?

[Harvey]

The GM Vortec is set up to run on 87 also.

[ssrgeoff]

Thats good news considering I have a 47 gallon tank..Thanks Harvey.

[Tige22ityper]

I get about 4 gallons per hour of use...........I can go about 12 hours with my 22i. I usually fill it around 10.5 to be safe..........I just forget about my ski season gas bill..........its expensive, and that's that.........what can you do about it? Its even more expensive when you take people out for the day and they throw you $5........like that's going to fill the boat!

[ssrgeoff]

Have them turn that $5 into $20 before they can even step foot on the boat.... dont forget, they need to bring the drink and snacks. Still cheaper than a theme park.. lol
