Captain's Report

Boston Whaler 170 Montauk running

The Boston Whaler 170 Montauk is an all-around fishing and watersports boat. While she has a familiar look, the design has been updated with the latest technologies and construction techniques.

Boston Whaler 170 Montauk running

Boston Whaler reconfigured the running surface and added 5” (.13 m) to the beam on the 170 Montauk to create a smoother, drier ride.


The classic Boston Whaler 170 Montauk has always been practical and highly functional. The latest version has been redesigned to add even more utility and versatility to this “hose-and-go” craft. The simplicity of the helm and adjustable seating features add to the well-thought-out interior layout. It comes with many fishing features and with an optional fishing package, the 170 Montauk can be used as a capable inshore and nearshore fishing platform. Everyone from novice boaters to experienced captains can appreciate Boston Whaler’s rugged design, which combines some of the latest technology with clean, classic good looks.

    Boston Whaler 170 Montauk running

    Boston Whaler improved the hull design, adding both 5” to the beam and a sharper bow entry, making the 170 Montauk more stable and with an exceptionally dry ride.

    The Boston Whaler 170 Montauk has a length overall of 17’4” (5.28 m) and a beam of 7’3” (2.21 m). With an empty weight of 1,700 lbs. (771 kg), a third of a tank of fuel, test power and two people aboard, we estimate the test weight to be 2,521 lbs. (1,144 kg).

    Top Speed. With the optional 115-hp Mercury Command Thrust FourStroke outboard turning at 5900 rpm, the test boat reached a top speed of 45.3 mph.

    Best Cruise. The best cruise came in at 3500 rpm and 22.6 mph. At that speed, the 3.4 gph fuel burn translated to 6.7 mpg and a range of 151 miles, while keeping 10% fuel in reserve of the 25-gallon (95 L) total fuel capacity.

    Acceleration Times and Test Conditions

    Boston Whaler 170 Montauk acceleration


    Boston Whaler 170 Montauk running

    With a more pronounced keel radius, the 170 Montauk performed well in tight turns and while being tested, no matter how heavy-handed, the ride remained firm and dry.

    The architecture of the Boston Whaler 170 Montauk’s running surface has been redesigned with a sharper bow entry and pronounced keel radius that make her easier to handle. The solid ride will please even the most experienced operator and give confidence even to a novice. When accelerating, the test boat showed nominal bow rise and reached top speed smoothly without hesitation. Driving through the photo boat’s wake to emulate rougher conditions, the 170 Montauk showed great aplomb knifing through the wake without any pounding. The 170 Montauk had just enough inboard roll in hard turns that the operator and passengers do not feel like they are being pushed to the outside. The simple design and competent handling makes the 170 Montauk ideal for anyone who just wants to have fun on a boat.

    Boat Inspection

    Boston Whaler 170 Montauk running

    With an advanced hull design and updated construction techniques, Boston Whaler retained the traditional lines that make the 170 Montauk a classic right out of the box.


    Boston Whaler 170 Montauk running

    Boston Whaler’s clever casting includes both a chock and navigation light and is beautifully functional. Combined with the centerline, 8” (.20 m) cleat, the bow setup makes docking and anchoring easier and more secure.

    Boston Whaler 170 Montauk bow rail

    The optional split bowrail makes boarding from the bow easier when beached.

    Boston Whaler 170 Montauk casting deck

    The forward casting platform doubles as seating, and is made more comfortable with the optional bow cushion.

    Boston Whaler 170 Montauk fish box

    There is a self-draining fishbox under the forward casting platform. The gas-assist strut allows for hands-free access.

    Boston Whaler 170 Montauk forward fish box

    Forward of the fishbox is the anchor locker.

    All Boats Should Have Anchors. While the mission of this boat is pleasure boating or fishing, owners should not forget that all boats must have at least one anchor suitable for holding securely in wind and sea state. Each type of bottom – mud, grass, sand or rock – requires a different type of anchor. Some anchoring situations also call for more than one anchor to be used simultaneously.

    Boston Whaler 170 Montauk sun lounge

    Shown is the sunlounge option, which creates a larger forward sun pad, but is not compatible with the bow cooler seating.

    Boston Whaler 170 Montauk cooler

    The 72-quart (68 L) cooler seating and console-mounted backrest with four rod holders are options included as part of the 170 Montauk fishing package installed on the test boat.

    Cupholders. The abundance of cupholders strategically placed throughout the forward cockpit reflects Boston Whaler’s keen understanding of how their customers use their boats.

    Boston Whaler 170 Montauk rod holders

    Shown is a detail of the four rod holders with tool and knife holders built into the backrest mount.

    Boston Whaler 170 Montauk

    The standard bowrail is 33” (.84 m) above the deck and the side rails are 30” (.76 m) off the deck. Note the optional console and helm seat covers.

    Boarding Steps. The standard port and starboard amidship boarding steps on the gunwales have molded-in anti-skid texture. Same goes for boarding steps molded into each side of the transom area. For security on the side steps, we suggest that Boston Whaler offer a latching safety chain for the opening between the bowrail and siderail.

    Boston Whaler 170 Montauk grab rails

    Shown here are the optional low-profile grabrails and optional teak boarding step.

    Boston Whaler 170 Montauk steps

    The 170 Montauk has built-in boarding steps in the transom with molded anti-skid.

    Center Console

    Boston Whaler 170 Montauk

    The center console is wider and taller than on previous versions of the 170 Montauk. But thanks to the additional 5” (.13 m) in the beam, the space on either side of the console is now 20” (.51 m).

    Boston Whaler 170 Montauk windshield

    The stainless steel grabrail surrounds the windshield and adds security when moving forward and aft.

    Boston Whaler 170 Montauk gauge

    Boston Whaler kept the instrumentation simple with a tachometer (yellow arrow), voltmeter (red arrow) and fuel gauge (green arrow), and five marine toggle switches.

    Signaling Horn. Under Rule 33 of the Navigation Rules, boats under 12 m MUST carry the means to make an efficient signal. A horn or whistle is the endorsed means to signal intentions or position. We recommend that horn switches be colored red for easy identification when needed in haste.

    Boston Whaler 170 Montauk storage

    The partitioned storage on top of the console has two drink holders, an optional compass in direct line of sight of the helm, the receptacle for the all-round navigation light (purple arrow), a 12-volt outlet (green arrow) and an optional USB plug (red arrow) to connect peripherals to the optional Fusion stereo.

    Boston Whaler 170 Montauk steering wheel

    Boston Whaler kept the helm basic with space for a 9” (.23 m) multifunction display in front of the stainless steel steering wheel with SeaStar hydraulic steering. Note that the console-mounted Mercury control binnacle has a cupholder to outboard and the optional Fusion stereo control head is positioned just above.

    Ignition Switch and Safety Lanyard. Often the ignition switch is mounted where it may be accidentally bumped into the off position. Normally the shutdown safety lanyard is integral with the switch. Boston Whaler has solved the issue by mounting the devices separately, with the ignition switch near the base of the steering wheel and the shutdown lanyard positioned separately on the front of the console.

    Boston Whaler 170 Montauk door

    Access to the interior of the console is through a portside door equipped with a stainless steel lift-and-lock latch. Inside the console is the battery box and battery switch (yellow arrow). Note the quick-grab storage bin on the inside of the console door.

    Boston Whaler 170 Montauk extinguisher

    The U.S.C.G.-required fire extinguisher (yellow arrow) is positioned horizontally in a recess on the starboard side of the console, where it is easy to reach if needed, but out of the way. A tackle drawer is included with the optional fishing package on the 170 Montauk.

    170 Montauk Fishing Package. Boston Whaler offers a fishing package for the 170 Montauk which includes a compass, four console mounted rod holders with tool and knife holders, a 72-quart (68 L) cooler with seat cushion and backrest, and a locker in the starboard side of the console that accepts tackle utility boxes.

    Fire Extinguishers. Fire extinguishers are required on any boat with enclosed fuel or engine spaces, enclosed living spaces, or permanent (not movable by one person) fuel tanks, and the Boston Whaler 170 Montauk has dedicated storage for one in the starboard side of the console.

    Boston Whaler 170 Montauk toe cutout

    A toe cutout under the aft edge of the console allows for more comfortable standup operation.

    Boston Whaler 170 Montauk bench seat

    The helm bench seat has a backrest that adjusts position. It can create a reverse-facing seat that makes it more relaxing to fish off the transom or watch family and friends as they swim.

    Boston Whaler 170 Montauk back rest

    The backrest can be situated in four different positions as a forward-facing seat, a more upright seat, as a leaning post or as an aft-facing seat.

    Boston Whaler 170 Montauk hardware

    Boston Whaler uses heavy-duty stainless steel hardware to secure the helm seat position.

    Boston Whaler 170 Montauk fuel tanks

    Previous 170 Montauk models had carry-on fuel tanks. The current models have a built-in 25-gallon (95 L) fuel tank beneath the cockpit deck.

    Grate Over the Scuppers. This is another example of Boston Whaler knowing what its customers need. By placing a grate over the centerline scupper, it is less likely that debris, such as bait wrappers or paper towels, will clog the drain.

    Boston Whaler 170 Montauk placement

    By placing the fuel tank under the deck, Boston Whaler freed up the space where the carry-on tank used to be located. Now there’s a storage box that opens aft.

    Boston Whaler 170 Montauk livewell

    Boston Whaler offers an optional aerated livewell built into the helm seat.

    Boston Whaler 170 Montauk aft cockpit

    The aft cockpit measures 6’ (1.83 m) from starboard to port and 3’ (.91 m) fore and aft, making 18 sq. ft. (1.67 m) of usable space. Note the four standard rod holders mounted in the transom.

    Boston Whaler 170 Montauk bench seat

    Boston Whaler offers an optional bench seat across the transom.

    Boston Whaler 170 Montauk transom

    The optional transom bench seat has a folding backrest that allows it to convert into a large sun pad.

    Boston Whaler 170 Montauk aft bench

    The optional aft bench seat contains a storage box.

    Boston Whaler 170 Montauk boarding steps

    Boston Whaler also can turn the boarding steps into optional jump seats with backrests fitted to the rod holders, improving crew comfort.

    Boston Whaler 170 Montauk steering

    Shown is the SeaStar hydraulic steering actuator and neatly arranged hoses and control cables encased in anti-chafe material.

    Boston Whaler 170 Montauk tow arch

    The optional tow-sport arch makes the 170 Montauk more versatile and family-friendly.

    Boston Whaler 170 Montauk ladder

    The swim platform has a convenient grab handle and a folding, three-step boarding ladder.

    Boston Whaler 170 Montauk swim platform

    The swim platform is also available with an optional teak surface.

    Boston Whaler 170 Montauk bimini

    The optional Bimini provides shade for those who prefer to stay out of the sun.

    Boston Whaler 170 Montauk trailer

    The Boston Whaler 170 Montauk comes with a standard galvanized trailer with swing tongue, LED lights, tie-downs, a torsion axle, trailer jack, and a winch with a nylon strap.

    Trailers and Salt Water. To ensure the longest life possible as well as the safety for those launching and retrieving a boat in the harsh marine environment, it is important to wash down the trailer with fresh water and soap after every use. There are products such as Salt-Away that offer a mixing fitting to attach to a standard hose. Inspect hubs, wheels, axles, lights, and springs often for function and corrosion.
