Mercury Discontinues NXT
 

Anyone know anything about Merc dropping the NXT1?

It was released in a press release to dealers last week. Builders must buy the #6 or a M8 now.

Did the cone clutch tranny have anything to do with its demise?

Thoughts on what this will do to the value of existing NXT boats? Big hit or non-issue?

Brett,
Is it just the NXT drive they're doing away with, or the whole transmission/drive package ?

Most likely depend on availability of rebuild parts (oem or aftermarket). I would assume the value of those drives for the 700hp range motors would be a still sought after drive if parts are available. The 6 is considerably heavier than the NXT on both the transom and pocket book.

The letter reads that it is just the NXT drive. The number 6 fits the same transom and transmission.

I doubt values will have any impact. They have a ton of the same internal parts.

Problem is the #6 is less efficient...making the boats slower or forcing you to move up in HP - so when is the turbo 700 or 850 coming out?

good maybe some people will start trying the Xpower drive now.

They won't be offered with a factory Merc powered build...

The 6 is the best overall drive period. Hydrodynamics are way better than the 8. I know a guy who tried even the M8Rs and saw no improvement. I know of a 388 Skater getting 1350s and is sticking with the 6s.

NA 850-900 DOHC is coming from what I've been told by reliable source. They aren't putting their life on it but pretty confident. Perhaps Miami boat show 2016!

I understood the #6 drive to be the lease efficient hydrodynamic design of the 3...I imagine each may effect a particular boat differently, but would really like to understand how each works from a hydrodynamic standpoint.

Correct me if Im wrong but I thought the transmission was the weak link in the NXT package.Are they going to upgrade that for the 6 drive or do away with the entire package?

I am sure there will be lots of opinions on this.... I believe that the cone clutch transmission design sucked especially when bumping up to Stage 3. But the cone clutch design consumes very little HP. I also believe that in many applications the lower on the 6 is a much better overall performing vs the NXT. In fact quite a few boats built with 700 engines and 6 drives on the West coast for that reason.

Mercury QC4V NA 850 hp already exists and is listed on their website as a Class 1 race engine

Not as much as you would think only 65 pounds.

Hydrodynamics is much improved with the newer M8's. Heard Merc Racing used Wilson to help resign the lower gear case. The problem with the turbo motors and the 6's is Mercury will only warranty the drive with 1:42 gears. The M8's you have choices.

Glad I went with this when I put my package together Whippled 525 EFI @ 750 hp IMCO SCX4 [ATTACH=CONFIG]539629[/ATTACH]

They aren't NA, they have little turbos

The 6 is actually the best, fastest. Like I said the new 8Rs still aren't as good as the 6.

Yes each boat is different. But also notice just how big the casings are on an 8. It requires at least a 17" diameter prop. Which I know on cats spinning out(which is what all the fastest set ups use) the bigger diameter prop makes the rear end very loose. If you like big rooster tail rotate props in. Lol

So in some aspects is one situation leads to other issues that can't be helped. I know talking to Bill when he was building the new 388 that he was concerned about the 8 lowers being able to get them blue printed down to handle the smaller diameter prop. We shall see now that he's pretty much done with the engine tuning and is gonna start really testing props.

Maybe when compared to the M8 but not always faster when compared to the NXT1.

Who gaf? 95 percent of the people on here will continue to put too much power through a pos bravo and keep replacing parts/drives, myself included.

Anytime Mercury discontinues a product it affects the used market value for the worse. Period

I suppose you're right.

have you ever owned a 6 or 8 to compare? or just going off what you hear? LOL, Just messing with you

Lol- well you already know the answer to that question.

Ya, from running Gary's boat, and yes talking to guys like Vinny and Mark

How can you post this if you don't own either? What type of boat do you own?

Simple- like I wrote: by talking to the pros and learning. Just like I've never played in the NFL but I know how to explain coverages and plays. I never said I had 1st hand OWNERSHIP EXPERIENCE. Nor do I believe one needs to own something just to know how things work and handle.

PS- nice job on your Eliminator, looks great.

Oh, ok. And thanks!

I help out Gary Smith with Predator, I just listen and learn. Observe and I'm around so I've just gathered knowledge from others.

Never ran an NXT but had 6's on a 39 TG. Can honestly say the NXT / 700 package is a little faster. 6's are longer. The new 8's are 2" shorter with an improved lower. Will see what the lower CG without burying the drive does for new boat. Will be able to give good comparison in three weeks.

What are you putting in front of the 8's on the new boat?

Pretty sure he said 1100 turbos in his build thread. I waiting to hear how his 42 runs also.

Yes, they are Merc 1100 turbos
