303 Question
 

how fast with either power 454's or 502's, NO I am not buying well at least in the near future :party-smiley-004:but me and a freind were talking and I was curious what these boats get for speed

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.

My 92 has later model 454 mags 385hp - with 25 3 blades, I'm right at 70mph.

My previous 1993 303 with Stock 502 Mag carbed, labbed 3 blades....72mph.

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.

thanks guys

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?

Dave

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?

Dave

Dave, nice boat. What was that coax outlet used for? Also, my plan over the winter is to upgrade the stereo in my 303. I already did the head unit, but want to add a sub or two and replace the speakers in the factory locations. Where did you mount your sub(s)?

(Sorry for the thread-jack.)

'96 303, 460 HP 454's, labbed 26" Bravo I's, full fuel, 2 dudes weighing a combined 500 lbs., 75 MPH GPS. I believe a 12-pack of Bud Select was in the fridge as well! :drink:

Coax was run back to where the shore cord connected with another wall plate. We have cable at our dock...TV!

As for the subs, I have attached a picture of where I mounted mine. This were not just mounted, but in a custom made speaker box to spec for the sub. They were 12" Memphis SQ series subs and sounded awesome!

Dave

I've got 2 10" subs in the back seat - planning on adding a third one in the center next year. These boats do not have much room in them, and I didn't want to take up too much storage. I also added a third battery under the seat. Even with that, I still have room for my box anchor.

I have a stock 95 303 with 454 efi mags 385hp 27 mirage props. It will run 74 mph with half fuel and my wife and I. It wants to chine walk above 70 a little tab takes away the chine walk but also 2 mph. I have had this boat since 99 and still love it.

got any pics

I have a stock 95 303 with 454 mags efi 74-75 on gps with half tank an 3 people

You guys with the 95 hull's and 454's. What are you guys seeing for cruising speed around 3200 rpms?

My '92 (same as '95 hull) runs 42mph at 3050rpm, and 51mph at 3450-3500rpm. Props are 24p labbed 4-blade.

I like the speed results you guys have, can anyone tell me how it compares to the 312? the prices arent far apart, also I thinnk I would go with a early year 303 if I did it the dash's look better then the later model years I wanna say 95/96 and the 92-94 are like my dash in my 271 the real trick is finding one w/o the pink:grinser010:like my 271[IMG]http://i495.photobucket.com/albums/r...s/HPIM2983.jpg[/IMG]
