Props for 33 Outlaw with HP500s
 

Guys,

Have spent a week with the boat and absolutely love it:D

The boat came with 24P B1s (not lab). Hole shot is incredible, but top end (with full fuel and 2 people) runs low 70s @ 4,900 ish.

Props seem on the small side to me.

Curious as to what any of you are running and what kind of speeds your getting.

Thanks.

Well, your recommended rpm range is 4800 - 5200 rpms. So, your props aren't really that much on the small side. Lab-finishing will surely bring your rpms over 5000, maybe even 5100, but typically for absolute all-out max top-end a 3-blade usually works best.

However, the 4-blades you have on there now on the other hand are better all around. Lab 'em! :cool:

that's what I'm thinking too

you were only 4900rpm's @ WOT? you need to be turning another 200rpm's. depending on the water and how i'll be running, i run 24P non-labbed or 26P labbed on my 33 Outlaw w/ 502's.

how was the water? smooth, choppy, rough?

what type of temps and humidity? high temps and high humidity could knock 200rpm's off easily.

Hey Dude,

I listening in here myself.

Just got to the office from dropping my 36 off at the dealer for the 20 hour service and a couple of minor repairs.

I have now run in at WOT a couple of times and have some numbers to report.

Running 500 EFI's with 4 blade 26 pitch props.

First time at WOT was just a short burst, had 12 hours on boat and only got 4600 to 4700 RPM. I now have 21 hours and Sunday with the wife and 3/4 load of fuel I got 4800-4900 RPM at 71 MPH.

Like you I am not getting all the RPM. The motors are starting to loosen up a little, and it looks like lab finishing will be the way to go. The 4-blades 26's absolutely work GREAT. Very easy out of the hole, they never blow out even on the hardest turn.

Speaking of turns, WOW, have you ever seen anything turn like these big outlaws? I am blown away. The 24 degree deadrise all the way to the bow is awesome. You can lay the rubrail down on the water and the props are pushing strong.

Keep me posted on what you do.

Thanks Mark

props?
 

Gentlemen,

I am curious, are all of you running 1.50 gears? First, if your boat is new and you are still in the break in period, I would not worry much about props or top end(especially if you are in the 4900-5200 range).

Once you break the motors in then you can start to really dial it in. The reason I asked the question about gear ratio is because I have a Baja 322 with 502's that I have worked a little(470hp on dyno) and I am turning 32 Bravo I's @ 5,000rpm, but I do run 1.65 gears. The boat has been radared(sp?) @ 76mph and runs 80mph on GPS. If I were to change to 1.50 ratio, I should still be able to turn a 28p Bravo I @ 5,000rpm. Once again I am just curious about the gear ratio for comparison sake.

By the way, the 33 & 36 outlaws are awesome, I have really been considering trading up for one.

Don,

Yes I have the stock XZ Drives that are 1.50:1 ratio.

The dealer told me that the boat will probably be delivered with 28 pitch props, but it came in with 26 pitch.

I can see the RPM's coming up on the motors in just the last few hours of operation.

We have not pushed it hard at all. Trying to break it in right and make it last.

Your boat is very nice. I have seen some of the post you have on TeamBajaMarine. Don't you also have prochargers on your boat?

Thanks
Mark

Hi Mark,

Perfect, the more time you take to break the boat in correctly the better off you will be. My guess is, by the time you are done breaking it in, you will have to move up to the 28 Bravo I's.

No, I am not running prochargers, currently I am naturally aspirated.

Have a good day,

In '98 Hot Boat tested a 33 with carbed HP 500s. According to the article the boat had 28" 4-Blade Bravo Ones. Boat ran 77.4 @ 4950 rpm. If anyones interested I could copy the article and fax it.

Don,

I have 1.50s also. My 33 is a 99, HPs have about 125 hours on them.

Boss,

Couldn't agree with you more:D

The ride is unbelievable too. My wife even commented that she hasn't felt anyway near this secure in our past boats (25 Outlaw and 26 Sonic).

This one is definitely a keeper! Looking forward to getting it dialed in.

OK JUST GOT HOME FROM LAKE TESTING MY NEW 33 2001 MODEL JUST FINISHED PUTTING IN 500EFIS HAD 502S WITH 23P MIRAGE PLUS IT RAN 68.7MPH ON GPS WITH 500 EFIS AND 23PMIRAGE IT RAN 73 AND HIT THE LIMITER AT 5400 RPM CHANGED TO 27PMIRAGE OFF OF MY 29 AND RAN 77.2 MPH AT 5200 RPM 5 MIN. LATER BUT DOES BLOW OUT THE PROPS FAIRLY EASY WILL TRY 28P NEXT AND WILL LET YOU KNOW HOW IT TURNS OUT CHOPPY CONDITIONS 85 DEGREES FAIRLY HUMID

Put synthetic, like Mobil one, in the engines and Amsoil synthetic in the drives.

Marty,

Good point, that's always good for about 100 rpm. Less internal friction will free up the engine a little.

Wow - you've owned a 25 Outlaw and a 26 Sonic. How did the two compare in terms of handling rough water? If I ever went back to a single engine setup, these two boats comprise the short-list.

Hey Guy's,

I could not agree more about the handling and ride of all Baja boats. I have been in just about every model from the 208 up to the 322(looking forward to my first ride in a 33 or 36 outlaw), and I have always been impressed and felt comfortable in the boat. Of course, that is why Baja does not want to go away from the tradional vee design, heck I am willing to give up some top end speed for a safe comfortable ride.

Have a good day,

TP,

I agree. After reading that two different OSO members got tossed out of two different Sunsations within the last month, it makes me glad I have a 7800 pound lead-sled.

ditto...the one thing my baja never feels, is light in the water. That is one of the reasons I named her Girthbaby...

Hey GAMEMAN,

I find it kind of amazing that you saw 77.2 on GPS with 27 pitch Mirage. I run 27 pitch Mirage and saw exactly 77.2 on GPS as well. That’s one heck of a coincidence. I wonder if it has to do with the fact that my 29 with HO’s has an identical power-to-weight ratio as your 33 with HP’s. I wonder if all the Outlaw hulls are so similar that a person could extrapolate power-to-weight ratios across the whole Outlaw fleet in order to calculate theoretical speeds.

If so, then:
It would take 594hp to push a 25 Outlaw 77.2mph.
It would take 1038hp to push a 36 Outlaw 77.2mph

Makes interesting food for thought.

29 Outlaw,

Well, thats an interesting comparison.

The Sonic is a lot heavier, and has a bit more freeboard, so you sit much lower in the boat.

I had to use the tabs quite a bit in the Sonic (hardly ever touched them in the 25 Outlaw).

In terms of ride in rough water, a slight edge to the Sonic. But overall, I think its a toss up. Better cabin in the Sonic, Outlaw is faster with same HP, Outlaw quicker to get on plane, etc., Sonic more unique graphics, etc. etc.

I'll take my 33 Outlaw over either:D

Updated numbers
 

Got some better numbers yesterday.

Full load (fuel and 2 people) with trim, I'm hitting 5200 on the nose with a top speed of 71.2 GPS.

Light load (fuel and 1 POB), I can hit the rev limiters around 55 - 5600. Speed 72.8.

Both runs in moderate chop, cool temp and low humidity.

Guess labbed 28 B1s may be the way to go. I'm hopping this will bring me up into the high 70s.

Anybody got any idea what the 28s may do to the hole shot?

Right now, with the 24s, its great.

Thanks.

A couple of years ago, Hot Boat magazine tested a boat just like yours. It was even purple and mulberry. I seem to remember them getting 77.8mph with 28's. I will have to find that article and check.

I'm pretty sure 29 mirage plus should put you at about 78-79 mph at around 5100, We tested gamemans boat and ran 77.2 at 5350 with 27's next we will try 29's and then bravo 28's, does anyone in the area have these props for testing

How's the hole shot and overall handling with the Mirages? Any blowout?

Blows out pretty bad, but he put 28 bravos on this weekend and lost only 1 mph send GAMEMAN a pm or e-mail and he can give you specifics

I LOST 1 MPH AND ABOUT 400 RPM BUT AFTER RUNNING THE 27P MIRAGE ALL WEEKEND WITH 3/4 TANK OF GAS AND 500LBS OF PASSENGERS PROPS DO NOT WORK WELL EVEN BLEW THEM OUT AFTER I WAS ON PLANE REALLY HAD TO BABY IT FOR SURE YOU ARE GOING TO HAVE TO RUN A 4 BLADE BOAT IS JUST TO HEAVY FOR 3 BLADES EVEN THOUGH THEY ARE FASTER HOLE SHOT ON THE 28P BRAVOS WAS GREAT AND WORTH THE LOSS IN SPEED I ALSO CALLED MERCURY RACING AND TALK TO THEIR HEAD PROP GUY PROMISED ME IF I LET THEM LAB MY PROPS I WOULD GAIN BETWEEN 300 AND 450 RPM AND GAIN 2 TO 3 MPH COST $320 I BORROWED MY 28P SO I AM GOING TO BUY NEW LABS FROM MERCURY SO I WILL HAVE BOTH SETS TO TEST AND WILL REPLY BACK ON THE RESULTS SHOULD KNOW NEXT WEEK PROVIDED MERCURY HAS PROPS IN STOCK

GAMEMAN,

Thanks. Let me know how they work out.

Spoke to Mike at Doller this afternoon.

I'm getting a set of 28 B1s tomorrow and will try them out this weekend as well. If they work OK, I'll get them labbed.

Hopefully, the hole shot will be OK. Its great with the 24s.

THE 28P SHOULD BE THE RIGHT PROP WITHOUT ANY OTHER MODIFICATIONS HOLE SHOT SHOULD BE GOOD LET ME KNOW ABOUT HOW MANY RPM YOU ARE TURNING PROBABLY AROUND 48 TO 4900 IF SO HAVE THEM LABBED BY MERCURY AND ONLY MERCURY THEY WORK WILL RAISE RPM BY ABOUT 300 TO 400 RPM WHICH WILL PUT YOU RIGHT WHERE YOU WANT TO BE AND SHOULD ADD 1 OR 2 MPH

Gameman,

Got the props yesterday, but didn't get a chance to run them. I'll do that next Friday and let you know.

Link to Hot Boat test
 

Attached is a link to the Hot Boat test (99 33 Outlaw with HP500s). Looks like 28 B1s are the place to start.

Hot Boat Test

Family and Performance Boat Magazine tested one a couple of months ago. It had 500efi's and was running 28 B1's. They only saw 4800rpm and commented that they thought it was over-propped. Nonetheless, they got 78mph out of it.

Hot Boat only got 4900. I'm thinking that if they run in that range (4800 - 4900) labbing should take care of it. Can't wait to find out:D

FOR SURE LAB MERCURYS WILL ADD 300 TO 400 RPM BUT ONE DRAW BACK IF YOU GET INTO SHALLOW WATER IT WILL DING VERY EASY AS I FOUND OUT THIS WEEKEND

ouch:eek:

Guys,

Just got a wierd call from my Marina. I asked them to swap the 24s for 28s. They tested it and siad they only got 4200 rpm:confused: The guy that tested it knows what he's doing.

The Hot Boat test (99) with 28s got 48-4900. With the 24s I could hit 54-5600. If I deduct a couple of hundred rpm per pitch, that would put me somewhere around 46-4800 which seems about right (I was planning on getting these labbed). The HB test didn't mention wether or not the props were labbed.

I haven't had a chance to try it myself, but am kinda shocked.

If that's the case, 26s may be the way to go?
:confused:

Results of the 28s: 42-4400 RPM, 68-70MPH

Results of the 24s: 52-5600 RPM, 72-74MPH

I still don't understand the Hot Boat test, 4900 RPM. Even with labbing, I don't think I could get that.

I guess its time to try some 26s.

If it helps any - I tried some Bronson Hill 26 B1's eariler this year. My boat has twin HO's. I had no problem producing RPM (5100-5200) but speed sucked compared to 3 blade props I had tried (I saw only 73-74). Your boat has the same power/weight as mine so perhaps some labbed 26's will fit the bill. It's just too bad that you can't go with 3 blades.

DID YOU TEST THE PROPS OR THE MARINA GPS OR SPEEDO 5600RPM SHOULD BE PAST THE LIMITERS MINE ARE AT 5400 RPM NEVER SEEN A 33 WITH 500HPS RUN 24P MAYBE THE TACS ARE OFF UNLESS THERE IS A DIFFERENCE BETWEEN HPS AND EFIS MY BOAT RAN 4800RPM WITH 28P BRAVOS IN 100 DEGREE WEATHER LET ME KNOW

No, I ran 'em (all speeds are GPS). With the 24s I'd "bounce" up to 5600. Very light load. Most of the time it would be between 52 and 5400. The boat came with 24s since the pervious owner really liked the hole shot.

The 28s were very disappointing in terms of RPM and speed. As I said, most I could get out of them consistantly was 4200. I was hoping for 4800, then I figured I could get them labbed and make up the difference. I still can't figure out why the RPMs were so low.

I pulled them off and am back to the 24s until I get some 26s to try.

You running 1.5 drives?
