Brand new boat has 23 hours on it and just seems slow...is it the fly-by-wire throttle? I burn 93 Octane gas and this is the 350 H.P. engine. Seems to me when you "Hit it"...it should pull my arms off...ideas?

What prop/transmission combination do you have?

Does the MCX ask for 93 octane? Just curious...
I also would like to see pics from your boat...

I ordered this thing from the factory last year. Stock 350HP engine and 13x13LH prop with the standard 1:1 transmission. Does not specify 93 octane...but heck...it can't hurt to burn the good stuff. My buddies Nautique is a slingshot compared to mine.

May not hurt but what's the benefit? I don't think the MCX has all that high of a compression for 93 oct.

What were you driving before this boat? Are you comparing only to the Nautique? What year, model and engine does it have?

Right there with you buddy!! For the extra $4 bucks a tank, why not?!?!?

your buddies Nautique came standard with a gear reduction transmission ...

No. I'm not comparing only to Mark's Nautique. My previous boat was a 1991 ProStar 190, and it only had 240 HP but just seemed peppier. The gear reduction in the Nautique seems to help, but my dealer says that hhe has the PowerSlot in his 197, and even his accelleration seems soft. Is it the smog control?...or the fly-by-wire?...or the increased weight of the new boat? Seems crazy.

no problem with holeshot on my 06 with the DBW ... so maybe its the cats? (PCM doesn't have cats either - they plan to meet emission standards w/o their use)

your not comparing simalar boats. your 91 was alot lighter and less surface area. new mc's do not have the hole shot of the other two of the big three.

I have posted this several times before...by running fuel above what is required you will make LESS power than you would if you ran the fuel specified for your engine. More octane make less power EVERYTIME unless the engine combination REQUIRES it. In conclusion not only are you wasting money but power as well...

Lastly, it has been my test results that a 2006 on average will outrun a 2007 and it has nothing to do with the emmisions.

I would argue for the "its all in your head" approach. I noticed no difference between my 2007 PS 197 w/ MCX 1:1 and my old 1996 PS 190 w/ LT-1 Powerslot. I run at about 2300 ft above sea level....

So, what is it ... I'll say this, my 2006 is 2mph faster after I calibrated it with GPS:)

Wow! I have never heard this before... guess I will start using 89 from now on. :o

Yeah...I think my next tank will be 89 octane, too, and I'll let y'all know. Thanks for the tip, SodarSki73!
