My 303 has 454 Mags (360hp ea. stock) that have been massaged with Barry Grant carbs, Barry Grant electric fuel pumps, Gil exhaust, MSD ignition, and the timing has been bumped a bit. I am spinning labbed Mercury Racing 4-blades. The boat will run every bit of mid-70s with 100gals of fuel without breaking a sweat. The previous owner said his personal best was 79mph on GPS. I personally am still learning the boat, but honestly I bet with a light load in the right conditions the boat could break 80mph. I have no idea what the boat would top out at in stock form.

There is another 303 on my lake with stock fuel injected 502s. The owner was friends with the gentleman I bought my boat from and he told me that my boat would "run away" from his. I do not know what his top speed is.......73-74 maybe??

Hope this helps.

96', 502's, labbed props, 1/2 tank of fuel, 300 # cargo, 75mph. I am sure I can get between 76-78 out of it.

I almost bought a '93 with carburated 502's. It went 72 on the demo ride. I found my 311 before I made an offer on the 303 - a little older (88) and slower (65) but a lot more room.

Was that 303 in Michigan that you test drove?

Yes it was. McMachen took it on trade and one of the guys that worked there had it.

Wonder if it was mine? All white sunpad, killer stereo system, custom dash panel with a flushmounted plotter?
