Does anyone know the cost on the Mercury 860?

[GRADS]

I'm just curious. I like the idea of having a naturally aspirated motor that puts out 860 H.P. with a two year warranty. This could be a game changer.

I'm guessing you'd have to run a #8 with it?

 

[HavaToon]

Don't know the cost but it's supposed to be mated up to a #6

I heard mid $90's. . .

 

[hallett21]

I heard mid $90's. . .

With drive?

 

[Justfishing]

since it is an NA I assume you could upgrade the hp when its time for a refresh. How much hp can a 6 drive handle. Can you get the 860 with an 8

 

[LargeOrangeFont]

At that price I'll buy 2 400r Verados, one more for a spare and a small Honda to drive around.

What upgrades do you expect to do to a highly strung NA motor like this? Anything you do to it will be tens of thousands. It is not a mass produced big block and you are stuck going through Mercury for parts. There are no intake options, the exhaust looks good already. If you change the cams you'll need 4 custom ground cams. You could have port work done, if it has not been done yet as part of this stock configuration.

I don't see you getting a ton more out of this reliably.

What about super charger or turbos?

 

[Outdrive1]

Tony told me Friday. For the life of me I can't remember but 86 pops into my head. That's including the drive.

 

[Outdrive1]

I think it has a 7k redline which is nice too. You'll be able to run smaller Pitch props and still pull big numbers.

If so that's a smoking deal. Remember not too long ago the Mercury 850 was like twice that price and had to be rebuilt very 25 hours.

 

[HST4ME]

He ain't buying one anyhoo. I'm willing to bet there is minimal difference internally from it's hairdriered big brothers.

 

[Singleton]

Now they just need a 680 and I think I would have my next motor.

 

[LargeOrangeFont]

What about super charger or turbos?

Certainly.. but just buy the factory one with turbos at that point.

Depending on the cams, it may not even lend itself to forced induction all that well.

 

[LargeOrangeFont]

That is awesome, but keep in mine this engine makes that kind of power because it revs to 7k.

 

[Rotten deal]

It's tuned to run 89 so you could probably gain a little when someone like whipple makes a tune to run 93 but it probably won't be much gain.

Yea it might make 900-920 on 93.

 

[Outdrive1]

Totally agree and it turns 7k because of the overhead cams.

 

[tkrrox]

Says 135k w m6 on Facebook. It says maintenance intervals twice that of the 1350. Does that mean it is higher maintenance?

 

[LargeOrangeFont]

Yea. A high strung NA motor will need more maintenance than a turbo motor with more mild cams. If that is true, this motor may not respond well to forced induction, so don't expect to get more power out of it.

That could be. I completely forgot what he said.

Stop it with all that reason!!

Throw a throttlebody spacer on it and a set of MSD coils [emoji23]

 

[Bigbore500r]

No I think it means you can run it for twice as many hours before maintanance intervals. Not sure on the cams, but the bore and stroke are identical to the 1300. It may the same internals minus the boost, which would make it last longer

 

[Tank]

Much respect to Mercury. They build and R&D the sh!t out of motors! They are doing amazing things. The new NA motor looks bad ass and 2 year warranty? That's crazy. But a proper built NA motor will get killer HP and extended life. I know Richie Zuls 750 N/A tunnel rammed motors routinely got 400 trouble free hours. Oh, and the #6 drive will take up to and over 1000hp all day long. The M8 is for turbo motors.

As if that's ever stopped anyone from trying LOL!

 

[pronstar]

9-liters / (552 ci), 9.75:1 compression...doesn't seem TOO highly stressed, does it?

I'd love to see the torque curve.

 

[GRADS]

I didn't know they still made the #6

 

[Tank]

I didn't know they still made the #6

Yep.

 

[SJP]

I didn't know they still made the #6

The #6 is the standard in the line up for the NXT drive

 

[buck35]

Speaking of drives, has anyone here heard of x power drives? Read a story by a guy a couple years ago by a guy who designed and built a new bravo style drive and was putting about 12 to 15 hundred hp to it with no problems. I think he was from az.

I've heard of them and you can watch videos of them in action . Not cheap but haven't heard of failures yet. I think there are a few 32 spectre cats with them. I believe you flip the helmet on the transom assembly to mount them . They appear to be good stuff as far as I know from the old interweb.

Yes, there was some great gopro footage, along with it.

That would be good news. The bill for a top end refresh on one of these would be frightening I'm sure.

Don't forgot the k&n filter that flows worse than stock

No, I'm sure it is plenty durable, but like I said.. I don't know where you'd go from there. I'd bet this makes great power from 4000-7000 RPM.

If so that's a smoking deal. Remember not too long ago the Mercury 850 was like twice that price and had to be rebuilt very 25 hours.

The Mercury 850 did not require a full rebuild after 25 hours. Mercury Racing scheduled service for the HP850SCI was valve lash every 25 hours (slightly different expense than full rebuild) , most of the credible Merc Racing Tec's suggested springs and lifters every 50 hours and you can R&R the lifters by simply removing the rockers arms and "fishing" them in and out, and replace the springs without removing the heads (I have done this all personally). If properly maintained you could easily see 200 hours or a lot more out of the HP850SCI or HP1075SCI before you have to touch the bottom ends and then unless it was hurt you could likely get away with Pistons and Bearings (machining etc) and back together..

The most abusive operational window on this generation of Mercury Racing engine was at idle because Mercury Racing ran light valve seat pressure (150 LBS) to make more HP but it creates a lot of stress on the lifter roller where it impacts the camshaft and lifters were breaking (they use Comp lifters which are not great). This is all correctable (if you know what to do and how to do it) for the sacrifice of a few horsepower and well worth it.

The 860 has not been officially priced (or at least I have not heard an official price) but if its in the $90K range with a #6 attached to it sounds like a bargain to me for what it represents. A very simple engine (simple = less parts to break or maintain) And the pricing delta between that engine and all of the Turbo engines (1100-1350 - is wide enough to make everyone buying the Turbo engine re think the decision, not to mention the warranty and 400 hour projected rebuild cycle.

Also very versatile - you could put them in a anything from 32-40 ft hull and still have respectable acceleration (on the larger hulls) and the big RPM capacity would help with wheel speed / bigger pitch etc. so decent to end in the bigger boats. In a 32-34 footer a really nice package although #6's are a lot of weight for the back of a 32.

Looking forward to see how they run...

 

[River Lynchmob]

Has any pricing been released yet?

 

[RiverDave]

Tony from DCB texting me this am the pricing on this motor. I couldn't figure it why, but now I know.. lol

It is 134,000 which is motor / transom assembly and M6 drive

 

[Englewood]

Wow...You could get 2 Teague 825's for that price!

 

[Andy01]

Wow...You could get 2 Teague 825's for that price!

With Transom assembly/Gimbles and #6 drives?

 

[DSMITH]

How much would a Teague 825 and number 6 drive package cost?

Is that MSRP? If so no one pays retail...lol

With Transom assembly/Gimbles and #6 drives?

Last I had heard and its been some years it was about $30k That's back when everyone was putting #6s on ski race boats so it has to have gone up a bit I would think.

 

[Stayin'ontop]

Anyone have any updates on this thread? Real world application? Pictures? Videos?
Haven't seen one on the water yet

 

[rrrr]

What about super charger or turbos?

Throwing a blower or turbos on a naturally aspirated engine specifically built for maximum HP would result in an unhappy combo that would probably blow up.

I can't imagine anyone doing so. A solid purpose built supercharged engine would cost less to begin with.

 

[Adam Croix]

With drive?

Yeah its 90k with drive

 

[Adam Croix]

90k with M8 drives and 6 blade cnc prop
