how old are they and what did they cost new
|
Those look awesome!
But what about water injection? Where does that occur? Someone needs to buy these - I'm not in the market right now after all the stuff I bought this summer - boat, trailer, lift. |
they are 2 yrs old with maybe 25hrs on them at most. they hook into your standard water feed line that comes into your factory manifolds. I put them on the 22 then pulled the motor apart and sold it to buy the HTM that i currently have. They will bolt directly onto the 22 and 23, just figured I would put it out there for you guys.

Okay guys, need some help to figure out what exactly is going on here.
Yesterday, for the first time in like 2 months, Georgian Bay was dead calm. So, I got to really put the hammer down. With 2 people and just under a full tank of gas, I saw an indicated 78mph at around 5200rpm. Now, here's the thing - I still had about 15% throttle to go. I actually backed right out once I saw the rpm reading because the max on the 502 is 5k rpm. I have verified that the prop is indeed a 25" Bravo 3 blade. So what prop should I upgrade to? Clearly, there's more top end in this boat, and I'd like to see just how much there is. I'd also like to know why the boat seems to be very fast for that hull/motor combo. I am wondering if I got a particularly strong 502 from the factory by the luck of the draw. I must say this thing is just awesome! |
is that gps speed or speedo ???? and you might want to have that tack checked for accuracy ,its funny i have a question about my scs as well,i just put a 26p 4 blade bravo1 on my scs and took it for a spin sunday with me 192 lbs. and my friend 220 lbs. and a full tank of gas 54 gals.at 7lbs.pre gallon =378lbs.my gps speed was 68.7 at 4,800 -4,900 rpms,now my question would be to anybody that might help me is how much more speed can i expect bye shaving some weight off ? like;; just me in the boat with 10 gallons of fuel ??? could that get my speed up to 75 mph? that would be shaving off 528 lbs.would that get me 6 mph more ??? thanks for your help don

I don't have a GPS yet, it's on the lie-o-meter. But how much error is in the stock speedo?

well my speedo reads 73 mph and gps says 68.7,, im sure every speedo unit is different
They do lie ... Anyway Full tank 2 people my boat barly breaks 70 .. With just me and 1/4 tank I get to 76 in a hurry Weight is a big factor once your prop + slip is maxed for the available HP with the stock 502 |

Depending on the day 76GPS = 80-82 on my speedo

Now the weight consideration is a whole different deal.With my race car for every 100lbs it sheds the car will run a 10th faster in the 1/4 mile.Same therory hold true for a boat but the actual mph gain I really wouldn't know.I think you might have more in that engine with labbing the prop. Oh....speedos are never accurate. |
Prostreeter,
Georgian Bay is fresh water and about 500 feet above sea level. Also, the water was calm, wind was zero and the air temp was probably 68 to 70 with no humidity. A perfect day. Hope to experiment a little more before the end of the season, but don't know anyone with a GPS that I can borrow . . . |
|
nobody intrested in the CMI's ??
|
That's a nice boat, but why does it need a recalibrated ECU with just upgraded exhaust? Seems like a waste of money to me.
I kind of like the bimini top, though. |

I'm staying bone stock because I plan to upgrade next year. But if I don't and these are still around, well... |
They are CMI sport tube lites. for 1600, these will be gone shortly
|
you wont need an ECU reflash with these. a full stainless long tube CMI for under 2k is unheard of. direct fit for 22 and 23 scarabs.

:cool: |
What do these go for new?
If it was a year from now, I'd probably buy them, but right now I have other upgrades to do to the boat. |

So you didn't actually use the decals I sent? Did you take them to a graphics design shop to have them made to your liking?If that's the case and you dont want them I'll buy them back.
