2001 25 Outlaw - SPEED ISSUES / PROP
 

I have a 2001 25 Outlaw with a 502 MAG MPI all stock with a 23p mirage plus STOCK

Best I get on GPS is 62mph @ 4500rpm 1/4 - 1/2 tank of gas with 2 people

I contacted bblades to lab finish, he says best Im gonna get is 2-3 more rpm and mph

Shouldnt I be able to get 68-69 mph on gps and closer to 5000 rpm

thoughts?????

Your motor could be tired? the 502 should push a stock 23 m+ to 49-5000 easily with full fuel and a cpl peeps. My 454 used to run at 48-4900 at 63.. best was spring 2 ft chop 64.7 at 5k.

Has it been tuned up? Wires, plugs, etc.

boat is mint with 185 original hours......

Rpm gauge right? Are you trimming out till it blows then down a touch? Should definitely push that prop faster.. what is your 4k speed .. should be around 49

trim it til it looks like a jet boat rooster tail.....lol

Whats your speed at 4k.. oh, are these GPS speeds?

If it is rigged at the stock X-dimension that Baja set and you're seeing a rooster tail you might be trimming up too much and in return the prop isn't working efficiently. There are a lot more guys with a ton more knowledge on this forum that might be able to help with your concerns.

Also, I would suggest searching around the Baja forum towards the bottom, you may also find help there as well.

This is a Mirage +? Try a Non+ Mirage, you'll get some more rpm and maybe a tad more speed.
If he is trimming too high his rpm would be higher & speed lower, I don't think that's it. Any Idea on your boat weight?

I thought of the RPM being higher as well, but if it is looking like a "jet boat rooster tail" with Baja's X and it being all stock then something is not right somewhere. Unless there is some kind of lab on the prop with a big cup? Play Loud 3, are you the original owner? Has there been any work done to the prop?

I will check that @ 4000

Im on the Chain o Lakes......right now no wake, water high from rain

Yes GPS Livorsi in dash type

2nd owner, I cant 110% guarantee prop not touched, But who I bought it from at 140 hours, they never used it, and a deep lake in WI

I have played with props before, especially in my 24 outlaw with a 500HP, ran a 25P lab finished from Merc Racing

yes Mirage Plus, 4750 dry weight,

You should be at 48-49 MPH so that will tell us if your rpm gauge is right.

I will recheck that as soon as they lift the "no wake"......lol

and I think I have another hand held GPS to use

This is kinda crazy.....

Went from a brand new 1995 257 PQ (from a 24 Maxum), to a awsome 1994 24 Outlaw custom made with the first 500HP in a 24 (for speed / handling), to a 1997 26 PQ Legend (for more interior room), to the 2001 25 Outlaw cuz I missed the speed and handling..........but something just isnt right

Sorry but I have never seen an outlaw with a stock 502 mag do 69 mph. I think the Outlaws are great boats but they are not that fast.

.....and I dont care if I get there, I think I need to be closer to 4900-5000 rpm and perhaps 67 mph on gps?

You need to post this in the Baja Forum, lots of 25OL guys there that may not be reading the General Boating Discussion Thread.

I would try to get your hands on another stock 23P M+ prop and try to compare apples to apples, you do have room for another 500RPM.

Did you check the obvious with engine; Wires and plugs, fuel filter, compression and leak down?

my friend who owns a marina is gonna get into it after the 4th, and yes looking for another 23p regardless, so I can get one lab finished

hi look at the.bottom. there is alot of hook built into baja after 98 you can see it by eye in the chines

definetly notice the difference from my 94

My 25 Outlaw with a 454 MAG MPI runs 63.9 on gps all stock with a 23p Mirage Plus 355 hours. I personally feel 68 or 69 with a stock 502 mag is asking a lot, being a Baja owner for a long time and knowing quite a few 25 Outlaw owners 65-66 is the norm. JMO

I had a similar problem with my 2000 Baja 272 w 454 mag mpi turning a 23 Mirage plus. Started to loose top end & rpm at wot. The electric fuel pump was not making enough pressure to feed the engine. It was at 20 psi when it should have between 36 & 42 psi. You might want to rule this out. good luck.

I wouldn't let b blades sharpen my lawn mower blade. Don't waste your money!

I will happily take 65-66

as I recall my 94 24 outlaw 500HP with a lab finished 25P did 5150rpm and 71-2mph......

OUCH....why?

and who would you suggest?

for my 24 OL I used Merc HP

that actually is what bblades said too

Just tried a lefty 23 mirage on my 25 AT tantrum with a 502 mag saw 62.4 at 5000 rpms with probably at least 1/4 throttle left way under prop for mine..but bettr than runnin my banged up hydro25

ok, just tried another 23p mirage plus used, same info 62mph gps @ 4500 rpm, in 1 foot chop

also, @ 4000rpm my GPS said I was going 54mph, as someone asked me to get info

You need to check your rpms gauge.. 54 is highly unlikely at 4k. My 25 was best at 50 in perfect conditions at 4k. I would say yours is 2-300 rpms off. So your probably running 62 at 4800.. that's what mine ran any day with the 23m+! Light, I could pull 4900ish at 63 in summer.

Oh, at with your 502, you should be able to push it over 5k for 65ish

yep something is definitely wrong, but at least both props achieved the same WOT rpm and mph

will get my Gaffrig RPM gauge looked at, but Monday my 23P is going to Merc Racings for a face lift....lol

Not sure what kind of boating you do, but I was always loaded and the 3 blade would lose a cpl MPH with the added weight. I ended up with a bravo 22p worked up to a 23p. You cold probably turn. 24p and lab it to squeese the rest out or try a 23p rev4!

Unless your usually light and looking for top end... can't have both :-)

Had a 2000 with 502. Well over what you have for hours on your motor. Best I ever got was 66.3 GPS with the same prop you are running but done BBlades.

I would be very happy with 66.3 gps....Monday my prop is off for lab finishing

2 people 99% of the time with 1/2 tank max, gonna have my tac looked at, and get one of my 23p lab finished

24p bravo 1 sounds interesting / lab finished, not sure what a 23p rev 4 is though...

Are you sure your not taping the rev limiter. I had the same prop on my last 272 baja 502mag. Best speed was 64.3 mph bumping the rev limiter. I went to a 25 4 blade. I can't remember what kind of prop it was though. I wouldn't send it out to have it labbed but that's just my two cents. Keep trying different props if you have friends that will let you try them. When I put the 25 4 blade on I lost 1mph but I was off if the rev limiter and it pulled a little bit harder as well.

I had good experience with lab on a 25p, so will try it for one of my props, not normally a fan of 4 blades, as past experience was loosing 2-3 top end on my 500HP

Assuming the tach is right and you are only getting 4500 rpm's with a 23 mirage + then a 24 bravo 1 would not be a good prop as it would probably put you close to 4100. A 22 bravo would be similar in rpm's compared to your mirage prop.

In my opinion, I think there may be something going on with the motor if it is in fact only able to spin a 23p mirage to 4500. My last boat was a baja 235 force and I built a mild 486 that was maybe close to 400 hp and it spun my 23 mirage + to 5000-5100. I ended up going to a 25 mirage+ to lower the rpms a little because I had a cast bottom end and didnt want to spin it that high. My point is I think that a 502 should be able to turn the 23 to at least 5000 with ease. My Baja was a little smaller, but don't think that is an issue here.
