Any 525's with NXT drives vs. bravo?

[DKwestern]

Curious of speed difference between bravo and NXT with same power?

[Coolerman]

i think you can only get the nxt with the 700...... someone correct me if I'm wrong.

I heard they're going to offer it with the 525.

You can get them with the 525 EFI's but Merc Racing site is confusing:

From 525 page (http://mercuryracing.com/sterndrives/hp525efi.php):

Engine drive packages include Bravo One XR, Bravo One XR Sport Master, Bravo Three XR and dry-sump Six drive. The optional Integrated Transom System (ITS) provides hydraulic steering on the drive while making the transom more aesthetically pleasing and simplifying installation.

From NXT page (http://mercuryracing.com/drives/nxt1.php):

Suitable for:
HP525 EFI
HP600 SCi
EU662 SCi
HP700 SCi

and then the warranty page (http://www.mercuryracing.com/techcorners/warranties.php):

Consumer performance outboards and sterndrives, with the exception of the 525 EFI NXT, 600 SCi NXT¹® 662 SCi, 700 SCi, 850 SCi, 1075 SCi and 1200 SCi engine packages are backed by Mercury's 3-year limited corrosion warranty.

I think the Lavey Craft canopy boat runs a 525/NXT combo...

[catmando]

Merc has a new "cambered" skeg NXT for single engine boats with the 525 and up. It's mounted at an angle so the boat will run straight when the wheel is centered.

Powerboat did an article on that a few months ago. Very cool!!

[catmando]

Powerboat did an article on that a few months ago. Very cool!!Yeah the pic was taken from the side which didn't show the camber. I wonder why they didn't take it from behind the drive so we could see what it looks like.

[magnum25]

What is the difference in performance? I know they dont make the NXT with the 525 yet but how does the 525 run with a #6 drive vs a bravo?

[DKwestern]

only because the nxt has a tranny would it be slightly slower, weight and drive efficency on the tranny accounts for 30-40hp.

But some #VI boats are as fast as bravos on the race circuit right? Super V and catlight. SSM props are more effecient?

[Geronimo36]

I don't have any figures to back this up but I don't feel the NXT tranny would soak up 30-40hp. A 72 Series trans, yes. The NXT tranny I'd venture to guess is only 15-20hp.

BTW, I'm trying to locate 3 complete NXT packages if anyone has some scoop.

True.

The NXT tranny is a cone clutch setup, much like a bravo,
the drive is a dry sump, and with the ability to run SSM props
I'm betting it runs better than a bravo boat.

[cowisl]

I would bet the NXT set up would be faster because of the prop choices that you can get.

Welcome!

[HPBoats83]

The 39' Lavey has 700's not 525's, and yes it's a bad bad boat!

[glassdave]

actually the cambered feature is very subtle and probably would not be visable to well in a photo. its a flaired section at the trailing edge of the skeg.

[Bullhead]

The Lavey SVL boat was running a 525 with the NXT drive....initially I think the prop choices were limited but they got it worked out...I have heard that the 525w/NXT from Merc was more $ than the 700 package...doesn't make sense

[MarylandMark]

Really? Your right, that doesn't make sense.

Anyone heard if just they are going to sell just the drive vs drive+motor combo?

[Geronimo36]

It makes perfect sense when you're a monopoly and don't want a potential engine competitor getting their hands on the drive! ;)

[Sea-Dated]

I would think the NXT would be fast simply because of prop choices but what the hell do I know. I think I am still drunk from Friday night.

[Rik]

The NXT is being replaced on the Lavey by a Bravo so don't use that as your yard stick.

Welcome!

thanks!

[Geronimo36]

I heard you can put a complete #6 on an NXT transom assembly. Anyone know if that's true?

[MarylandMark]

Beak Boaters 38 Fountain has NXT w/dry sump 6's hooked to them

[Wrinkleface]

Pretty sure Jassman's 43 NT has # 6's w/ the 700's!

[MarylandMark]

Jazzman's has "pure 6's" - no NXT parts IIRC

[Knot 4 Me]

I heard you can put a complete #6 on an NXT transom assembly. Anyone know if that's true?True. Jassman's 43 NT is setup this way.

[MarylandMark]

True. Jassman's 43 NT is setup this way.

I thought Jassman's was "all 6's"?

So do all the 700's have the NXT transom assy and then what you add after that is your call?

You have to add a hull water pickup when you put a 6 on a
NXT gimbal.

[Salesmanship]

Wow lot's of good stuff here. :ack2:

Retail price for 525's NXT is $73,790.
Retail price for 700's NXT is $87,421.

You can substitute the drive portion with a SSM VI. That adds another $27,000 to the retail list price. However you still have the NXT transom assy w/ the integrated dry sump transmssion. That's basically a large cone clutch.

Jassman has 700's w/ NXT transoms and SSM VI drives. Mercury does not offer the 700 w/ a complete SSM VI package.

Just the facts Ma'am.

Do they take out a vertical shaft on the #6's when you order them with the NXT gimbal assy? Thanks for the info Terry :)

[Perlmudder]

what is the point of running a 6 on a nxt assembly? why not have all 6 or all nxt....?

[MarylandMark]

Just the facts Ma'am.

Good stuff and thanks for clearing it up!

Fountain had some handling issues with the NXT on some of their
boats with 700's when they first came out, installing a 6 in place of the NXT cured these issues.

It had something to do with the gearcase shape of the NXT.

[Beak Boater]

Fountain did have some handling problems, also water pick-up problems, with the NXT gearcases. Because of the high X's plus too much stern lift with the NXT gearcase. On the 38's they were running out of skeg in the water making the stern move around at high speeds. #6's with the longer skeg and less stern lift fixed that problem. Plus going to thru-hull water pick ups fixed that problem as well. I have not seen but heard the new NXT gearcase has a longer skeg. The NXT transmission is alot shorter than a normal Bam, Cyborg transmission. You could go all #6 but having the motors staggered you would loose even more cockpit space running a full size transmission, at least in a 38 Fountain.

[Geronimo36]

Are the internals in the NXT the same as the #6?

If it bolts up to the same transom assy. and the lower case looks different and it accepts #6 props, what are the internal differences?

And then he figured out where the throttle was and recoverd. I can't wait till spring to go visit again!

Great pics MentalPause!!

when in the hell did you take those shot's:dupe:especially the second shot with me wiping the drool when the Baja passed us.click..at the wrong moment.:ack2:..btw..Collette is the only invited this year:cheers2:

You make me LMAO. I have other shots - you know - wax on and wax off!:ack2: Oh, maybe Sandy has those!

Colette needs a driver - so when she goes I go - and no friggin sea food for her. Make sure the cooks have the blackened chops ready.:biggrinjester:

By the way - get a more creative avatar - like mine!:sifone:

[northernoffshore]

I am not a fan of nxt. The blunt bullet and cone clutch trans seem poor in design. IMO they should of tried a similar set up like the konrad drive.

The Lavey SVL 525 picked up like 4MPH, but quadrupled the prop budget.

Dont know about pricing.

the Lavey boat gained 4MPH & CNC milled props are hella expensive.

unfortunetly no one knows the exact anwser with out speculation.

[Bad Idea Baja]

I would be willing to replace my IMCO's with NXT's if someone had a pair for me. I'll do this just so you guys can have the answer. :sifone:

[Uncle Dave]

Just found out the LaveyCraft guys are pulling the NXT drive from their rig despite picking up a few MPH-

- they don't like the way the boat handles with a single NXT- duals apparently are ok.

Not sure what they will go with but Im hoping they'll put an Ilmor drive on it.

Same here.... as a charity case I'd be willing to do all the work on my boat to facilitate the swap! ;) :26:

[Dreamer]

36 mti at show had 525s and nxt

[Mentalpause]

Be intersting to see how many people will try the Ilmor drive now...

[Team Tsunami]

36 mti at show had 525s and nxt

Had Six's on NXT assemblies.

[Madpoodle]

Miamuh Merc booth had a 525 w/NXT. Guy in booth said that for single apps they were using a wedge on the skeg much like on the eggbeaters...
