Depends on how much hp, boats load, your style of driving and what your trying to achieve. My boat came with a 502 mpi, it ran a HONEST 62 mph stock with 23 pitch merc 3 blade. I tried a bunch of diff props and saw about 64 mph but it wouldn't always run that fast with the "fastest" prop unless boat was running light. Some guys run a 22 pitch 4 blade to get good crusing and take off with a little less top end. If I still had a stock 272 I would be inclined to try a 24 pitch 4 blade cut down labbed prop but keep in mind they are about 1000$ new. You could give Greg Hittner a call at Cutting Edge , he is building some real nice props and has the best price on new props if you go that dircetion.
A few things I WILL tell you:
1. If you are fairly new to this boat, BORROW, don't BUY a new prop to try, I ended up owning about 10,000$ worth of props from all my experiments!
2. IF you are going to modify it, do your mods FIRST before wasting your time trying a bunch of props
3. THE MOST IMPORTANT THING: Don't believe the speeds claimed on all these 272 Baja's that guys will tell you, I have heard claims as high as mid 70's with stock 496's/502's etc and many claims of high 60's/ low 70's with stock "black" motors. I think I have only read about 500 Threads in past 10 years on here where someone has tried 10 different props, saw mid 60's and just can't belive there boat is 5+ mph SLOWER than everyone else's STOCK Baja's. I have a 2000 272, it runs 100 mph (with 1100hp) and looks stock. I have paced at least 50+ 272's and 25 outlaws that were stock and not one has EVER broke 70 mph (GPS) and most were lucky to run 65/66 mph on a good day, light on fuel and passengers, down stream with a tail wind , Smitty

haha..so true

It is getting a 582 at about 720hp. i have been running 3 blade mirage plus's till now.
And where i am its impossible to borrow. Everyone around here runs 18-21 ft boats with stock power

I had a 98 272 that dynoed at 728hp at 5300 and I ran a stock 30p bravo. I think a 30 or a 28 bravo will be your best bet. Also you should add hydro steering if you don't have it.

zeke

got imco single ram full hydraulic and an HP transom assembly in it last year.
what did you see for mph out of youre 272?

indywhsle

I sold it before I could really test it. The guy I sold it to is on here. His screen name is pacalim1965@yaho. I think he has seen over 90 and runs high 80's all the time. Get it touch with him to confirm.

Your going to end up running a labbed 28 or 30 depending where your peak power is and assuming you have a 1.50 drive. Don't waste your time with a 3 blade. I have had many engines in my 272- ran mid to high 70's with a blown 600-650 hp 502 turning a 26 and 28 4 blade. Ran high 70's to mid 80's with 750 hp 540 turning a 28 or a labbed 30. Ran 89-92 with 950 hp turning a labbed 30 or 32. Currently runs 96 at 6200 turning a labbed 30 and will run 99 or so turning a labbed 32 6000-6100 with 1050 hp. With the blower belt off running normally aspirated at 650 hp runs 74-76 with a labbed 26. Definately try a prop before buying, I doubt you will turn a standard 30 at the rpm you need, I would be pretty sure a 28 or labbed 30 is going to be about right on your boat unless you have it over cammed and hp peak is 6000 plus, then I could possibly see a labbed 28 that is tweaked a little in your future, all depends on the rpm's of your hp peak and if your out ripping around with 1 or 2 people and 1/4 tank of gas or fully loaded . It doesn't sound like your running a blower, N/A boats are a little harder to prop as they have less tq and are more temp/load sensitive, Smitty

Artic is right on! My 272 with a stock 502 ran a max of 63.4 5100 on gps last year with a worked 23 Mirage that came with the boat. I added Stainless Marine exhaust flashed the ECU and had Greg Hittner at Cutting Edge lab a 23p Mirage plus which he suggested I add some cup and shave down slighly it rides the bow up higher now and handle the rough better then ever! (GREAT WORK) Even after that only running 65.00 @ 5200 but I'm happy nice cruise and handles like a champ. All readings were with full tank loaded with cooler and beer
