Mercury "Vengeance" Prop
 

I was puttering around my boat last night (new and haven't had it in the water yet) and was taking a look at my prop. It is a Mercury "Vengeance" 23p. It is on my Baja Outlaw 20'. I haven't seen anyone mention this prop on this site before, so I am assuming this prop sucks. I have seen the Mirage mentioned quite a bit. Is this something I should consider replacing?

Also, is the Mercury prop selector worth a darn? My prop is 23p and they are saying that at a minimum I need a 26p prop. Looking at the description of the Vengeance prop is doesn't even support the HP I am running (350 MAG MPI, 300 hp). The prop is only supposed to be used to 250 hp. Are the folks at Baja idiots or is the Mercury site too generalized?

P.S. The Baja Outlaw 20 is a 3K lb. boat with Alpha drive with 1.62 gears.

Well you defiantly do NOT need a 26p prop. A three blade 23p sounds about right. As for the Vengeance, I have never herd of it. I would find someone who has a Mirage 23p and see if there is a performance difference. It will not matter if the prop you are testing comes off of a Bravo or not because they are interchangeable. When you do, report your findings, we would like to know.

my 16 donzi classic came with a vengence. pretty much an aluminum prop made out of stainless.. ie entry level non real performance stainless..

i've progressed waaay beyond those days now...

the mirage is a popular propeller for a lot of applications... but not always the best for every boat... it helps to try a good variety... mercury, turbo, hydromotive, and so on and so forth...

a lot of factors determine which prop and style of prop will perform the best on your boat...

The vengence prop is definately not the best performing prop out there...It's kind of an economy performance prop.

A Mirage in a 19 to 21 pitch should give a nice improvement.

I think, but am not sure, but the mirage may also have a slightly larger diameter.

I have had a lot of good luck with turbo props.

Why would you recommend a step or two down in pitch?

pointerman,

First of all congratulations to you on your new money pit, I mean boat.

Jaroot is right. The Vengence is a Black Max aluminum prop but cast in Stainless. It is a prop that provides adequate performance for a wide variety of boats. That's why manufactures put them on the boats. It's also the cheapest stainless prop Mercury makes.

Your options are almost endless as far as prop selection goes for your boat.

I suggest that you get the boat on the water and get some time in it. After have had it in a variety of water conditions then you can decide what you want from a prop.

Each of the different props has different characteristics and is designed for a certain type of boat and application. When you have a better idea of what you use the boat for then that narrows down the type of prop you need.

There is no such thing as a "best prop". What works for one may not work for you.

Congratulations on your new boat and happy boating.

I have to strongly disagree with you.

The Vengeance is a fantastic prop! Every bit as good as a Mirage just a different blade set.

What makes the Vengeance props different is the Diameter of the blades. The Vengeance line has a smaller diameter than the Mirage. Similar to a Tempest.

I've done extensive prop testing on my 22 Pachanga (my buddy owns a marina) I had found a bit over 3 mph gain with a 23 Vengeance over the 23 Mirage Plus. In my case, the little Pachanga would not pull the big diameter of the Mirage (14 5/8" I believe) and ran about 300 rpm's more with the smaller dia. Vengeance of the same 23 pitch.

Over the past 2 seasons I've tried many props and for this 22 Pachanga the Vengeance was the fastest by a longshot.

The Vengence is recommended for boats 22" in length and less. But again there are many props to select from. I would suggest getting some seat time and then set forth some performance goals. You may be quite happy with the Vengence for your performance goals but every Driver/Throttleman is different in the style.

As Matt said "there is no such thing as the best prop" The best prop is the prop that acheives your goals....I beleive Biggus has attested to this. He is obviously very happy with the performance of his boat...and that is what it is all about.

With your boat, you'd do much better with a Laser II than a Mirage Plus. The Mirage Plus really works best on 22+ foot boats with big block power. I also don't agree that the Vengeance is crap. It's not top of the line, but it is a good solid prop. If you have a hole burning in your pocket, try a Laser II 23P. Otherwise, stick with what you have.

By the way, how did you end up with a 350Mag in your 20 Outlaw? I thought the 5.0MPI was the only available motor.

The vengence has a smaller diameter.

-----------------------------

No one said it was crap, just not the best performer out there. Let's face it, it's not a top of the line prop.

My old Baja Hammer, which was 21 feet, 3300# and had a 350 MAG(very similar to pointerman's boat, btw) came with a vengence 23P...I put on a 19P Mirage Plus and it totally blew it away! I gained about 3 mph top end with a much better cruise.

is right again,the laser -two 23 pitch is the best prop for the 20 outlaw,usually they come equipped with a veng,its not that bad ON THIS BOAT. and its a pretty darn good prop for a 20ft boat or smaller with a mercruiser.

the laser two- will give a little better bow-lift ,
and acts, and looks like a mirage .

usually on this set-up the laser -two runs about 2.5 mph faster over the Veng.

Nick, it sounds like you had the wrong pitch to begin with. You would've had a 1.50 gear (or 1.47 if it was an Alpha) which means you should have had a 21P. Otherwise, you would have never gained speed going from a 23 to a 19.

All I'm saying is that with the size of a 20 Outlaw and the power he has, the Mirage Plus is really too big of a prop. He will lose holeshot because of there isn't enough low-end torque on tap to drive the prop. (Unless he drops to 21P as you suggested, in which case he will lose top end). Even if he does gain top-end, he'll gain more with a Laser II because he most likely won't have to drop to a 21P. For anything larger than a 20 Outlaw or 202 Islander, the Mirage is most likely the better prop.

You very well may be right, Ric.

Just want to relay the point that the 19P Mirage performed very well on my Hammer, a similar boat in size and set-up. :cool:

Thanks for all the info. I'll try it for a month or so with the current prop and if the hole shot is plenty quick I'll go ahead and purchase a Laser II to see if I can get any speed gains and still maintain a decent hold shot. I do plan on using this boat for tubing, skiing, etc. so I do need to maintain quick planing capabilities. I am hoping that the trim tabs will also help with that when skiing.

Good question. My boat was apparently made custom for as a retirement gift for a Baja Exec (according to the dealer). He put a few hours on it and then signed it over to the dealer for sale. It hasn't ever been registered so it still carries the full warranty on motor and hull. It has a few other options that you don't normally see coming out on the 20. I really don't like the white 20 Outlaw and hadn't planned on buying one until I saw this particular boat.

on the 20' outlaw
 

what type of exhaust comes with it?

thru -transom with silent choice?

or thru prop only?

if it's thru prop the Laser would really benefit with the vent holes in the hub barrel.

My boat has Corsa Quick & Quiet so running at speed will be thru transom.

Any other benefits to the Laser?

nice,Thats the way to go .

The Laser -two will work great!

What kind of prop would you recommend on a 3500lb 1996 Donzi 22 Classic with a totally stock 502MPI 415hp with Bravo 1 drive? Now running a 25" Mirage Plus at the rev limiter 5050rpm doing 74.5 on GPS, bouncing off limiter slightly.

Thanks very much,

can you post a link to some pictures of your 20 otlaw? i've thought about buyng one myself.

You had to do some digging to find this thread !!!!! Look at the date it was posted!!!!! :ernaehrung004:

If I currently have a 23P Mirage, what pitch Vengeance should I be looking for?
