Some interesting new models from Boston Whaler:

2018 Montauk 150: https://www.bostonwhaler.com/family-o...tauk-2018/

2018 Montauk 170 https://www.bostonwhaler.com/family-o...tauk-2018/

Let the discussions begin!

---

The Montauk 170 now has an integrated fuel tank (25 Gallons) like the larger Montauk 190 and 210 models.

It also received a bump in max HP to 115.

Plus more locker storage.

At first glance, it has become a lot more interesting than the previous version. It seems to be a more viable alternative to the older classic Outrage 18/19 and Outrage 17 models.

New 2018 Montauk 170 Specs:





Compared to previous 2017 Montauk 170 Specs:

---

It's a shame they didn't bump up the max hp to 70 for the 150.

---

I agree.

It is funny though, because the artist's renderings of the new Montauk 150 show it with a Merc 90.

It seems like the 2018 Montauk 150 may not have been built yet -- I haven't seen photos, only renderings. Whereas the 2018 Montauk 170 has a full photo gallery.

---

This gets confusing.

First, the Classic Montauk 17 weighs about the same as the current 150 Super Sport and current 150 Montauk. Yet the old Montauk was rated for 100HP versus 60HP for these two 15' boats.

The 2017 and earlier Montauk 170 is a HUGE boat compared to the above ... at 1400 pounds, 500 pounds heavier. And rated for 90HP. The 2018 Montauk at 1700 pounds is nearly double the weight of the 150 SS, 150 Montauk, and old Montauk 17. It should have a heckuva lot more HP rating.

Compared to the classic Montauk 17, the new 170 Montauk (and especially the 2018 170 Montauk) are massively bigger boats, like the old Outrage 18 (even it was lighter). The deeper V hull and the added weight make the 170 Montauks much better riding in chop, by most accounts--but I have no direct experience with the new Montauk ... is it better?

And yet, the 190 Outrage is yet heavier than the 2018 170 Montauk.

As the feature set comes closer together, will the Outrage line move up in size, dropping the smaller boats in favor of Montauks and/or Dauntlesses? There does seem to be a lot of overlap in the lineup, and that cannot be good for costs of manufacturing or marketing.

---

Bill, those are good questions.

I see the current and 2018 Montauk 150 as the successor/rough equivalent to the old classic Montauk 17. This new 2018 Montauk 170 seems to be pushing into the niche previously filled by the old classic Outrage 17/18/19 models.

Where this leaves the current Outrage 190 is an interesting question. It has been in production since 2004, so it may be coming due for an update as well. Perhaps we will see some big changes there.

Or maybe BW will eliminate the 190 Outrage and the Outrage line-up will become the 23'+ fishing series, with the Montauk series filling the 15-21' size range? Dauntless of course would overlap with both those series, but at least Montauk and Outrage would no longer overlap. That might make product selection a bit easier for would-be customers.

---

I think we should start calling it the Montauk 170 II so as not to confuse the two different versions.

---

Phil: you're right.

The Models and Specs page ... is it complete up to a certain size of BW boat? Does it have all the models from the largest boats listed downward? If not, do you need help tracking down info for not-yet-listed boats?

Also, I realize that Whaler Central is really about the care and feeding of "Classic" Whalers, yet the Models and Specs does include the newer Whalers (destined to be classics ...). Is there a philosophical reason not to include all the newer, larger Whalers? There are gazillions ...

---

Good point, Phil.

Although, BW refers to the existing models as the "170 Montauk" and "150 Montauk", and calls the new models the "170 Montauk 2018" and "150 Montauk 2018."

So maybe we should follow their lead and put "170" first? That would make these new models the "170 Montauk II" and the "150 Montauk II."

It does get confusing, that's for sure. But not as confusing yet as Outrage 19, 19 Outrage I, 19 Outrage II, 19 Outrage III, and 190 Outrage!!

---

I agree about the II no matter where you put it.

170 Montauk II
or
Montauk 170 II

If you look in the 2002 and 2003 Boston Whaler catalogs, even Boston Whaler had the same variations on the names of the 170 Montauk.
The catalog shows 170 Montauk listed but the decals on the boat were Montauk 170.
So it really didn't matter which comes first except for alphabetizing the names in a database.

Looks like I will be making some changes to our Models section.

That looks good, Joe.

For what it's worth BW seems to be using a "170 Montauk" decal on the side of the new (2018) 170. And the artists rendering of the (2018) 150 shows a "150 Montauk" decal.

The 170 Montauk II is really growing on me. Some of you guys may remember I was considering a new 170 Montauk I a few years back, but ended up with a used 19 Outrage II. I really like the 19 Outrage II, but I'm not sure I would have gone this route if the 170 Montauk II had been available. It checks a lot of boxes for me. I'm looking forward to seeing one in person -- possibly at the Annapolis Boat Show in October.

---

Not much difference in the 150 Montauk versus the 150 Montauk II.
Same length, beam, weight, engine sizes, etc.
It only seems the draft is 2 inches more, but why?
http://www.whalercentral.com/userphot...owstart=60

---

I was wondering the same thing. It makes me question whether the specs for the 2018 150 Montauk II could be preliminary, and they are just using the old specs as a place holder? But then there is that change in the draft (yet same deadrise of 16 at the transom??)

The big difference I see in the new 150 Montauk II is a change in interior layout. The outboard well is gone, and the optional live-well seems to be gone too. The bow locker area has been reworked. The floor space seems more open, although the RPS seems larger too.

It would have been nice to see this model get a bump in max HP (like the 170 Montauk II), maybe up to 70-75 HP (the classic 15 hulls were rated to 70 HP, and they were a smaller/lighter boat.)

---

Did anyone note the loss in swamp capacity for the Montauk 170 II? 600 lbs reduction compared to the Montauk 170. 2800 lbs vs. 3400 lbs

As these boats get heavier, it goes down significantly.

---

Maybe that is partially due to the removal of foam from the interior hull to accomodate the 25 gallong fuel tank and tank plumbing?

On the plus side, the new 170 Montauk II does have a 250 lbs increase in payload capacity.

---

A Whaler dealer in Florida (MarineMax) has a decent walk-around video of the new 2018 170 Montauk II:

https://www.youtube.com/watch?v=bedii...ediijYovtQ

---

What did he call it?

Why does the Boston Whaler website and the youtube video show 170 Montauk on the side.

I guess I will pull it with my brand new 2017 Ford F-25

No wonder the general public doesn't have a clue what to call their Whaler even though the boats name has a decal on the side that says:
170 MONTAUK

Thanks for sharing that video.
Made me laugh for sure.
Does look like a nice new model though whatever they want to call it.

---

"17 Montauk."

I guess old/bad habits die hard.

Yes, the video showed the boat fairly well (although too bad he didn't climb aboard and open up some more lockers, etc.) But I was also surprised that a dealership had one of these new 170 Montauk models already.

---

Oh, I am not so sure I like the stainless rub-rail all around. I can't argue with wider beam, deeper V, the fuel tank change, etc. This 170 Montauk II is a monster ... will kick butt on Lake Erie. My dream boat was always the old Outrage 18 (mid 1980's), but that dream has got to be replaced ... and probably the Montauk series is where it's at. I suppose I'd take a 190 Outrage if I won it in a raffle ... but for all of these, I'd have to get a new truck to pull 'em ...

Happy with my current boat ... and the one big thing I could use more of is not OAL, but good weather days to get out in ...

---

The internal fuel tank in the new 170 would be a big negative for me. You're gaining 3 gallons of capacity and a LOT of additional complications over the life of the boat. That's a terrible tradeoff.

I do like the additional horsepower option though - and the larger motor has both better cruise speed and better mileage. Seems like a no-brainer to me.

---

The stainless rubrail is an option. It would probably outlast the standard rubrail by a longshot, though.




The tradeoff is you are gaining a ton of storage space that previously was taken up by fuel tanks under the RPS.

Previous versions of the Montauk suffered from a lack of storage -- most gear had to be piled on deck instead of stowed away properly. The new 2018 170 Montauk II now not only has a second bow locker, but has a large storage locker under the RPS where the fuel tank used to sit on deck (optionally this can be a livewell.)

I feel the built-in tank is a big plus.

---

Is there access to the fuel tank, or is it molded in? I couldn't tell from the pictures.

---

Walt, if you go to BW's website and click on the 2018 170 Montauk model, there is a "gallery" of photos. In photos 3/10 and 7/10, I see what looks like a deck hatch under the RPS and extending back to the sump. It appears to be screwed down. My guess is the 25 gallon fuel tank resides under this hatch. Hopefully it is a removable/replaceable variety of tank, and not molded in.

---

Boston Whaler has now added performance tables for the larger 115 hp Merc Fourstroke/CT engine option.

The 90 hp Merc Fourstroke/CT does somewhat better on fuel economy at slow displacement speeds, but the 115 actually does better and has a greater range at mid-range planing speeds.

The 115 has the boat up on plane doing 16.3 mph at 3000, whereas the 90 only has it at 11.1 mph (at 3250 rpm, the 90 hops up on plane.) The 115 yields a top speed of 46.0 vs 40.0 for the 90.

It sure seems like the 115/CT engine is a worthwhile option for this new Montauk model. However, it's a $990 option!

---

https://youtu.be/pLB6oecnYBs

---

The cruise speed (defined as the planing speed which gets the best mileage) for the 115 is 3 MPH faster. That is very significant and would make a lot of difference to me.

Honestly they should have offered the 115 on the previous 170 - it always felt to me like it needed more power. With the newer model being quite a bit heavier, I'd expect it to feel even more underpowered with the 90.

---

One of the first 170 owners, Tabasco, replaced his new Mercury 90 with a 115 on a Montauk 170 back in 2002.

Extrapolating from this would infer the Montauk 170 II should have a 135 or 150hp.

Remember Boston Whaler tests the boat light. 25 gallons of gas, 20 lbs of gear (anchor probably) and two people in 80 degree weather.

---

Maybe the Merc 115 ProXS Fourstroke would be a good choice? California ARB certified that engine at 126 HP.

I can't see why Whaler wouldn't offer it as an option on the 2018 170 Montauk?

---

Max engine weight listed is 410, the actual weight of the 115.

---

Phil, Which 115 is 410 lbs? Is that the ETEC 115 dry weight you're referring to?

The Merc 115CT Fourstroke 20" and the 115 Pro XS 20" have a spec dry weight of 363 lbs. Plus 5.5 qts crankcase oil, and maybe 1.5 qts gear case oil? So let's add another 10-11 lbs? That gets us to just under 375 lbs "wet."

Or do you have some intel about the "actual weight" of these engines that is not published? I'm genuinely curious to know. Thanks.

---

JRP,
Don't forget to add about another 15 lbs for a 25 inch shaft for the 170 Montauk II
http://www.whalercentral.com/userphot...lbum_id=84

Mercury seems to be the only outboard manufacturer today that wants to keep everyone in the dark about how much any of their longer shaft motors weigh.
They only list the "lightest model available"
https://www.mercurymarine.com/en/us/e...ifications

One of the reasons I discontinued the Engine Weight Reference Guides.
http://www.whalercentral.com/articles...p?cat_id=4

Never have been impressed with those type of tactics from any manufacturer.

---

Most of the 115hp were around 400-420 dry but then Yamaha and Mercury introduced lighter 90 and 115 hp's.

Adding fluids, prop adds a good 20 lbs to get you very close to 410.

There is a reason why the max rating matches up to the Mercury 115 hp weight. The rating is synched to the product offerings. That is why whenever a new engine or reduced weight motor is introduced, the hp offered rises on subsequent model years.

i.e The Nantucket was first introduced with a max hp of 115 and a weight limit of 510. When the I-4 Verado line was introduced the hp max increased. First to 135, then 150 and now stands at 200. Engine weight for the 200? 510.

---

I missed that they had increased the transom height on the new 2018 170 Montauk II to 25". Aside from the extra engine weight from the longer shaft, that actually seems like another improvement over the previous Montauks.

So if the Merc 115 Fourstroke CT 25" shaft with prop and fluids is pushing the 410 lbs weight envelope, that would likely make it the only 115 on the market that will meet the weight spec for this new 170 Montauk II. (All the other 115s on the market are heavier.)

---

FYI, BW has added a more extensive photo gallery of the new 2018 Montauk 170, including quite a few interior detail shots:

https://bostonwhaler.smugmug.com/Seri...ew-Photos/

Also, on the 2018 Montauk 150 page, they now have at least one photo of an actual boat.

---

They show 3 photos of the new 2018 Montauk 150 and I noticed a single tank under the RPS instead of the two 6 gallon tanks of past. Also the CC shows a much larger access door and a nicer face for the electronics. Simple changes but for the better. The different color options would be liked by my admiral and the teak steps won't work for me as I have retractable cleats for spring line and/or fender mounted there https://photos.app.goo.gl/KVbM0Aaivjk...ivjkIecDG2&https://photos.app.goo.gl/qBYxCvssKXD...sKXDq57K22 plus when the bimini frame is up (allways when we boat) a 6ft big guy like myself has a hard time stepping on board thru that triangular opening. I just step on the corner aft deck steps behind the side rails next to the motor.

Does anybody know if they show 60th Anniversary in the Boston Whaler arrow logo on the aft sides for either the 170 & the 150 as they did in 2008 on my boat. See below
