I know 1 guy that has the 454/310 mpi and it runs 70 ish. If a 502 were installed how much faster will or should it be? Greg

i'd say 75-80ish. 100extra horse power no extra should do it.

c'mon, I had a 1995 with a 300hp LX carb,bravo= 63 mph with a 23" Mirage plus----MAX.How can an extra 10 hp= 70 MPH ? MICHAEL GARIBAY

97 23' SCS 502/415 does 75 ish. Dont know how much different the 22 is ? How much is 22 weight ? The scs is 3740 lb.
Factory spec sheet reads like this ...
Time to plane 3.29 sec
Top Speed 75.1@4920
Cruise Speed 50.6@3500

Mike I know it sounds funny but its the truth. I ran against that boat in my stingray and we were neck and neck at 71.2 MPH. Now we dropped in a 502 and it runs 75 ish(hasnt run it empty yet) Greg

Don't feel bad been called a liar since I made my post. I was starting to believe that I was damebramaged and didn't see the gps correct or mine was somehow wrong so a borrowed a Friends this weekend and ran 75.3 with 3/4 tank I originally posted 76.1 with 1/4 tank.
So oh well .. I am trying a taller prop next week. I bought a lab finished Mirage + 29P will let you know if it goes faster or falls on its face :-)
I am shopping for the best price on a Procharger for the boat now. Will be a couple of paychecks down the road.

I had a 22 with 400hp small block with an Alpha 1 drive. With just a couple hours on the motor, 6 adults jammed in with cooler full of ice & beer..69mph. I guess the 22degree deadrise also helps. I did find from riding it hard that the deck was not attached to the hull very goog & the screws were always working their way out & I had some good strees cracks. Other than that, a great boat. We even use to pull a Parasail with it.

I have a 22 scarab fitted with a 502mpi with an upgrade ECM, dry exhaust, Cam and with 2" shorter lower unit. The problem I cannot tell you what is the max mph cos I will be putting the boat in the water in a couple of months. As soon I have results, I will inform.

Put it this way, I wish my 29 with a 502 went as fast a my 22 with a 454

Hey John , I have a 23SCS that is tight with 4 and a six pack...I would love to see a picture of a 22 with 6 people and a cooler in it .. was like the "how many can you squeeze into a VW thing :-)
