    Gas???

    I have a 07 Wake Pro 215. It has always performed well and has low (20 something) hours. Sea Doo recommends premium fuel (93 octane) because of the super charger I guess. The manual says regular (87 octane) minimum. I have always used premium. Will I do any damage if I start using regular gas? Gas is getting pricey. Thanks.

    Unless i'm mistaken the ECU will make adjustments for lower octane fuel. I personally run premium in mine, not sure if the ECU "detunes" the engine when you run 87.

    I have always used regular in my GTX's (2003 4 tec supercharged and 2011 RXT iS 260). They both run great. You would probably get better (faster) performance with premium, but like you say, it is expensive. The boats are very fast with regular.

    ECU monitors for detonation, if any detected it retards the spark timing causing a slight decrease in hp.

    i use 87 (regular) on all of my seadoos... if they dont like it, off to the junkyard they go

    besides, 87 is more eco friendly.. for my wallet..

    as far as a slight loss in HP.. i couldnt really care less, 70 mph is fast enough, even if its on the dream-o-meter..

    think of it this way, in 1 fill up, you could save about 2.50-3$
    i do about 20 fill-ups per season, if not more, thats 60$ in savings, which, could result in one more fill-up and one more fun day on the water..
    IMHO i jetski to sight-see , fool around, do tricks and spins, head out into the lake and take a swim, sure sometimes a good WOT moment happens, but oh well.

    Ok $6.40 per tank of fuel difference! come on better get a none SC ski. It cost more to run the skis than it ever did to run the go fast boats. it's the price we pay to play.

    P.S. Don't modify one $7.00 a gallon for race fuel

    Only premium here. The later models say 87 minimum but my 06 says 91 plus. It's never seen anything below 93.

    For people who actually ride, it's a PITA to find places on the water who have 91 or higher. Mine has seen 89 a few times with no troubles.

    So you've put 20 hours on the ski in 5 years, that's 4 hours a year... At 50.00 to fill up and run for 2 hours with premium, you're averaging 100.00 a year.... So you might save 10.00 a year...

    If you're worried about that, come fill mine up for a summer, lol... 50/50 mix costs about 70.00 to fill up and I had to twice on Sunday...

    Let me know if you ever want to sell that ski.

    I didn't even realize I could run anything other than 93 octane. LOL
