I ordered the 23 mirages and am now running 66mph but bumping off the limiter.

I am going to look for some 25s after i sell the 22 power techs, and the 23 mirages.

Thanks for the input everyone.

I have a 2000 with 350 MAGs. I see mid-high 60s on GPS. Never hit the 70 mark.

Has anyone ever tried turning their props in?
If so what was the result?
Speed and handling.
Thanks

i'm interested in the guy with whippled scorpions running low triple digits...is this possible?? I've considered running a 28zx with prochargers on a pair of 350mags.. any idea if this will break the 90MPH mark?

I figure that the whippled scorpion boat runs around 105 or so. More is possible. Those engines do not make close to the claimed 650hp though. It is probably a pretty dang fast boat though.

I have ridden in a single 28ZX at 91mph. I actually drove that boat yesterday into the 80's and it was pretty happy. My 26ZX has a running surface that is very similar to the 28ZX. It is just 16" less in front of the first step My best speed is 103mph.

Regarding the 28ZX vs the 27ZR. I hear that they are different animals when it comes to size. You should look at both of them.

The Procharged small blocks has been done. I heard that it ran in the 90's pretty easily.

These boats have a nice hull that wakes up when good power is added.

Prochargers units do work on the earlier model stuff, we had done a lot of procharger stuff in the past. We do more whipple stuff lately tho.. I must say that, The whipple is a nicer more robust kit. Especially for the later model SBC merc applications. It does cost more tho too.. Jamie / Lakeside

my 28zx gets 71 on gps with 23" mirage props. The trim is the key.

What is your drive ratio? What is your limiter at? They have changed over the years. Some of us have 1.65 drives. some have 1.5 drives. The older 350 Mag boats had a lower top suggested RPM (5000) the newer ones have 5200 suggested limit with a 5300-ish rev limiter.
