Yamaha 252 SD: 25-Foot Bowrider Reimagined

By Capt. Steve

Yamaha’s new jet-driven 25-foot bowrider is what the company refers to as “The 25-Footer Reimagined” and they’re pretty much on target.  We tested her and found a top speed of 43.8 MPH.

Overview

The new Yamaha 252SD is the builder's latest launch that pushed the boundaries of what a 25-foot boat can be.  There are improvements in every area... comfort, technology, handling, fit and finish to create what may be the ultimate Yamaha bowrider.  

Technical Features

Not only is this boat exciting and versatile, but it also adds a boatload of technical improvements – most notably in the form of the Floating Connext Touchscreen.  This screen has several features, such as fuel level, battery voltage, bilge pump, blower activation, water depth and time that are permanently docked regardless of what screen is selected.  At the top are seven icons to select alternative screens. 

The floating Connext touchscreen has to be the highlight of the 252SD helm.  Notice to the side there’s also a cellphone mount.  It can be rotated to the portrait or landscape mode.

Home – will always return to the main screen.  This will show the stereo control to one side and water temp to the other, when in float mode (engines not running).  Start the engines and the display reverts to showing the two tachometers with gear indications at the bottom, and boat speed in between the two. 

Map – switches the screen to a GPS-based moving map.  We can scroll in or out on this map and even revert it to a full screen, which will still be inside the permanently docked icons discussed earlier. 

Trip – this screen includes data on trip distance, fuel used, fuel flow, water temp, average speed, highest speed and engine hours.  Most of these are resettable of course. 

Cruise – This page gives us the ability to dial in target speed and acceleration curves for watersports.

Music – gives us controls over the source of our tunes and the ability to control the various levels for volume and tone. 

Switching  The boat icon allows us to control the tower courtesy lights, the water pump for the stern shower, helm lights, interior courtesy lights with the dimming capability and the forward dock lights.

System – Finally, there’s the system controls that provide access to the main menu to set the language, current time, Units (MPH, knots, etc…) as well as the boat’s wellness, which means intervals between various maintenance requirements. 

Because this boat is now “fly-by-wire” it allows Yamaha to add some convenience features.  First is a push-button start for both engines.  In the lower right corner of the Connext screen is an icon showing the throttles.  That’s a regular dual-throttle mode.  Touch it and it reverts to a single-lever mode that allows for controlling both engines with one lever.  Of course, the engine RPM’s will be synchronized in this mode, but with dual lever, as long as the levers are close to each other, the engine will still self-synchronize.  Now touch that icon one more time and it reverts to DRiVE technology, and this is a game-changer that we’ll discuss in a moment.  Lastly, there’s Cruise and No Wake modes that allow for holding speed at the touch of a button, and further being able to adjust those speeds incrementally with up-down buttons.  

Not only is the Connext screen touch-capable, but it can also be controlled from the joystick right alongside. 

DRiVE Technology

DRiVE Technology allows for controllability at the dock by using dual paddles at the backside of the steering wheel.  The right paddle is for forward (go right ahead) and the left is for reverse.  Both are progressive in that squeezing them more adds more throttle, but never more than docking speed. 

So in this manner, we can be standing at the helm, with one hand on the wheel, and dock the boat effortlessly just by turning the wheel and activating one paddle or the other.  It’s a huge deal and so much more comfortable than having to sit and manipulate the usual engine controls to try and get that docking down right. 

These two paddles behind the wheel control the throttles and shift when docking significantly, and intuitively easing the docking procedure. 
Yamaha’s proprietary DRiVE Technology allows for effortless docking while standing up and never taking the hands off the wheel. 

Features Inspection

Stern

Yamaha has always done an exceptional job with its stern gathering areas, but with the 252SD it’s taken it to a higher plane of functionality.  There are still the two levels, as usual, but now the lower level includes a padded backrest for times when we’re sitting directly on the platform with feet dangling in the water.  This adds the first of several additional comfort features. 

This latest iteration of Yamaha’s transom seating takes comfort to a new level.  It also adds versatility with several convenient alternatives.  Notice the side mount for the cockpit table and the speaker.  Another thoughtful touch is the two elevated steps to each side easing entry and egress from the platform. 
We can slide one or both of the aft seats forward adding versatility to this popular area. 
There’s now storage access under the aft seatbacks. 

The upper level, really an extension of the cockpit seating, is now more of an actual seat that includes sliding seatbacks with storage access under the seatbacks.  Being that they’re sliding now means the seats can be utilized as just an aft-facing seat or even a chaise lounge.  Finally, not only is there a side mount for a cockpit pedestal table, there are two pedestal mounts just under the rubrail at the transom.  These will accommodate custom-made units that can serve as underwater seats one way, and when flipped upside down, revert to tables over the water.  This is a huge deal and remarkably innovative.  Of course, Yamaha also includes the freshwater shower, stereo remote and speakers at this popular location. 

Here we can see the pedestal table to the right, and to the left is the same unit flipped to form an in-the-water seat. 
We can also move the table from the bow or cockpit and use it at the platform.  This stern area is clearly not an afterthought on Yamaha’s part. 

Cockpit

Even though this boat still has the typical 8’6” (2.59 m) beam, it’s carried much further to the outside creating more space than we’re used to in a typical 25’ (7.62 m) boat.  We measured 37” (93.98 cm) between the opposing seats, as well as a cockpit depth of 37” (93.98 cm).  The two seats consist of L-shaped lounges with high bolsters serving as backrests.  The starboard seat also functions as an aft-facing seat with an additional backrest at the forward end, up against the refreshment center.  At the walkthrough to the transom seating, we can add a filler cushion to create full wraparound seating from one side to the other.  We can add still more seating by swinging the helm and observer’s seats around to join the crowd. Both of those seats are thickly padded with a protruding headrest and flip-down armrests. 

Ahead of the observer’s seat, there are two storage compartments and a storage cubby between two beverage holders. 
The refreshment center consists of additional counter space with a Marine Mat non-skid surface, a beverage holder and storage underneath. 
Flip the seatback aft and it supports even more counter space.  Storage is beneath.

It’s hard not to appreciate the fit-and-finish in this cockpit.  There are multiple tones of upholstery, contrast bead-welting and heavy stitching.  The upholstery is heavy duty so it's able to withstand the rigors of the marine industry.  To the bulwarks, there's a grab handle, a little storage area with a net, speakers and beverage holders.  All this is repeated to the opposite side and there’s even a subwoofer to the port side. And of course, all the decking throughout is non-skid rubberized Marine Mat.   

All of this is protected overhead by the collapsible sport tower 6’6” (1.98 m) off the deck and it supports not only a tow point 3” (7.62 m) higher, but a fore and aft bimini as well.   

Walkthrough to the Bow

Between the consoles, there’s plenty of storage.  There’s a door to the port side of the helm console plus another hatch in the deck leading to storage there.   However, the real star of the storage show has to be in the port console accessed from a side door that opens into the walkthrough.  Inside there's utility storage.  We also have dedicated storage for the cockpit table, and we can configure this as a head by putting an aftermarket Porta-Potti in, thanks to the 4’ (1.92 m) of headroom. 

This compartment is roomy enough to add an aftermarket Porta-Potti or use it as cavernous storage. 

Bow

The bow area also has its share of upgrades.  Yamaha carries the beam well forward so there’s more room to the interior.  There is the usual configuration of dual lounge seats, one to both sides, much as we see in nearly every bowrider.  However, not one's to stop there, Yamaha also brings versatility.  Remove one, or both, forward cushions to add regular chair-style seating to the mix.  Add filler cushions to create a large sunpad or move those same cushions back to create three across forward-facing seats. 

All of this versatility also comes with the usual wrap-around bolsters, a built-in, self-draining cooler fully forward and a rubberized non-skid matting on both a step and the hatch over the anchor locker to facilitate bow in boarding and even beach reboarding. 

With multiple configurations, the bow of the 252SD presents a lot of versatility. 
Fully forward is a non-skid step to the foredeck.  Underneath the hatch is the anchor locker and beach reboarding ladder. 
There are speakers, beverage holders and connectivity recessed into the side bolsters.  Just above, a small grab handle has been reverted to a lengthy grab rail for more comfort and safety while eliminating pinch points. 
Under the anchor locker hatch, Yamaha managed to do what others can’t seem to grasp… fitting both an anchor and a reboarding ladder in the same space.  Just ahead is a centerline pull-up cleat for securing the anchor rode.

Performance

The Yamaha 252SD has a length overall of 24’6” (7.47 m), a beam of 8’6” (2.59 m) and a draft of 19” (48.26 cm). With an empty weight of 4,612 lbs. (2,092 kg), 30% fuel and three people on board, we had an estimated test weight of 5,343 lbs. (2,424 kg). With the engines run up to 7400 RPM, our speed topped out at 43.8 mph. Best cruise came in at 6000 RPM and 32.2 mph. At that speed, the 13.3-gallon per hour fuel burn translated into 2.4 miles per gallon and a range of 153 statute miles.  All while still holding back a 10% reserve the boat's 70-gallon (264.98L) total fuel capacity.

Power for the 252SD is a pair of 1.8 liter High Output Yamaha marine engines turning 14.7 mm stainless steel impellers out of 155 mm high-pressure pumps. 
Best economic cruise was found at 32.2 mph providing a range of 153 statute miles. 

Handling

As expected with any Yamaha boat, the 252SD has exciting handling characteristics. With the twin 1.8L high output engines, she’s quick out of the hole.  We reached planing speed in an average of 2 seconds flat, continued through 20 mph in 5.5 seconds and right on through 30 mph in 8.5 seconds.  She has ¾ turn steering that has most jet boats spinning out in the turn, but Yamaha has eliminated that and kept the boat in control throughout.  I noticed no chine walk or adverse slide to the turns and only a little bit of speed bleeding off.  I also noticed that even without the single lever feature activated, if the throttles are anywhere near close to each other, the engines will automatically sync to each other. 

Options and Pricing

One of the ways that Yamaha is so successful is that it builds its boats one way, the right way.  They don’t offer options, but rather different boats with different features.  For the 25’ series there’s, from low to high, the SX250 ($57,999) built for play, AR250 ($60,999) for watersports versatility, the 252S ($74,499) with more to love, the 252SE ($78,899 that raises the bar still further and the 252SD ($82,999) at the top of the pyramid with DRiVE, fly by wire technology, more interior space and plenty of versatility. 

Observations

It’s clear that Yamaha was trying to raise the bar on just what a 25’ boat could be, and they seem to have hit the nail on the head.  Combine the roominess, upscale features, versatility, technology with jet power safety and it’s simply a winning combination.
