    Captain's Report

    Sea Ray 21 SPX docked
    The Sea Ray SPX 210 OB models have a LOA of 21’6’’ (6.55 m) and a beam of 8’6’’ (2.59 m). Outboard power choices are either a Mercury 150 FourStroke or 200-hp Mercury Verado. Sterndrives can be a 220-hp 4.3L as standard or a 220-hp 4.5L MerCruiser.

    Mission Statement

    Sea Ray has created a new group of entry-level, affordably-priced runabouts called the SPX Series. The SPX 210 and SPX OB are watersports-focused bowriders with flexible seating in the cockpit and with either outboard or sterndrive power. Value-priced either way, the new 210 SPXs should appeal to a wide audience who go boating on a budget and want to keep operating costs low, while at the same time have good performance.

    Goal Oriented Design

    There are basically three goals to the SPX boats that Sea Ray wanted to embody…

    1. Highly Customizable.

    What typically happens in competing boats in this class is a manufacturer will add features such as a watersports tower, or a fishing package, and then call the boat an entirely new model. That’s not the case here. Buyers of the SPX will choose their model, either 19 or, in this case, 21. Then choose propulsion….sterndrive or outboard. And then choose a package that supports what they want to do. There’s an Elevation Package ($4,633) that leans towards watersports, an All Sports package ($3,467) that embraces fishing and skiing. There is also a brand new select package that transforms the SPX 210 into a Luxury Sport Boat. The package ($5,267) includes an upholstery upgrade (with two color choices), premium finishings, a helm upgrade, LED lights and stainless steel upgrades, and SeaDek platform matting. And for what it’s worth, Sea Ray also offers numerous hullside and pattern color combinations for the SPX boats! So clearly there’s a lot of customization involved in the purchase of the SPX. But Sea Ray has made the purchase process easier by creating an automotive style configurator, which is an entirely new concept to this particular market segment. And we think it’s a pretty good idea.

    2. Totally Affordable.

    The goal is to offer the Sea Ray hallmarks to an entirely new audience. These new boats have, by far, the most aggressive pricing throughout the company’s entire lineup. Certainly these boats can be had for less money than the “Sport” lineup, which previously served as Sea Ray’s entry-level boats.

    3. Thoroughly Sea Ray.

    No corners were cut in the build process, and all materials remain consistent with the Sea Ray brand. This is a boat that will not only appeal to first time boaters, but the level of attention to detail, along with the fit and finish, will ensure brand loyalty.

    So What Does SPX Stand For Anyway?

    We’re glad we asked. When creating a new lineup, Sea Ray wanted to not so much abandon its old models, but build on them. It already had its entry-level boats, the “Sport” lineup. Plus, it had the luxury lineup, the “SLX” Series. What needed to happen is to create a new and affordable Sport line but keep some (but not all of course) of the luxury, fit-and-finish of the SLX boats. The combination of the two is what became the SPX line, sporty but luxurious at the same time.

    Ready to Play

    The well-styled SPX 210 comes standard with the basics for water fun, but sport aficionados will want to upgrade either model with the ‘Elevation Package’. This factory-installed set-up includes items such as an aluminum tube wake tower with board racks, an integral Bimini top and a ski mirror.In addition, there is an option for the very handy Perfect Pass control system that allows the pilot to set tow speeds for each individual. This takes the guesswork out of pulling skiers and ensures they get the same pull each time. No matter the sport, a large locker in the sole of the cockpit provides storage for skis, boards and other toys.

    Sea Ray 21 SPX birds eye view
    This bird's eye view of the new SPX 210 OB shows the tremendous amount of seating that is available in this affordable sportboat.


    The outboard version we tested had the standard Mercury 150 FourStroke mounted to the stern. As an option, a 200-hp Mercury Verado can be used.

    Sea Ray 21 SPX outboard choices
    Two choices are offered for the outboard version. A Mercury 150-hp or 200-hp.

    The sterndrive version of the SPX 210 comes equipped with MerCruiser’s 4.3 liter, multi-port fuel injected V6 with Emission Control Technology (ECT). This engine produces 220-hp while meeting the latest EPA clean air standards, and is coupled to an Alpha 1 sterndrive with aluminum prop.

    An optional engine upgrade

    is MerCruiser’s new 4.5 L V6 that cranks out 250 horses with ECT, has an Alpha 1 drive and a stainless steel prop. Although there is only a 30-hp difference between the two, the 4.5 is the latest in propulsion technology and will work better in high altitude or hot environments, and it comes with an stainless steel prop which should mean slightly better performance.


    Consumers can also downgrade to a 4.3 L 190-hp engine and receive a $1,400 credit. This might be an appropriate option for someone who just wants to leisurely cruise around the lake or up and down a river and doesn't need a lot of power for towing sports.

    Test Results

    We tested the outboard version of the SPX 210 with the standard Mercury 150 FourStroke. She had excellent performance reaching a top speed of 46.5 mph and did so with a 14.5 gph fuel burn.Her most economical performance came in at 3500 rpm and 27.4 mph. That speed reduced the fuel burn to 5.5 gph and the SPX 210 OB could keep it up for over 6 ½ hours and 181 miles.


    The boat’s 3,400 lb. (1,542 kg) dry weight and a 19-degree V-bottom hull was designed to provide a smooth, dry ride even when the water gets lumpy, yet not be so deep-V that top speed and fuel economy are drastically affected. Indeed, we were impressed with her handling on our choppy test day.Naturally at top speed we could generate some pounding, but pulled back to a reasonable cruise speed showed a surprisingly cool ride up and over the swells while staying dry. With the light chop she would skip from one wave to the next with a smooth re-entry producing yet another enjoyable ride.

    Sea Ray 21 SPX bow
    Note the rounded bow that maximizes interior room and provides additional room for a non-skid surface for bow boarding.

    The Bow

    The bow area offers comfortable seating for three in the form of lounge space for two facing forward, and one facing aft. In this manner a comfortable social area is created. That aft seat also makes a comfy observer’s station when towing as it has the added benefit of being directly in the line of sight of the captain.

    The removable seat cushions

    reveal storage compartments below, while a pair of rubberized grab handles provide security while underway. Both consoles have backrest cushions for facing forward and there is another in the bow for a person facing aft.

    Sea Ray 21 SPX bow area
    The bow area is a compromise on any boat this size but we still have room to stretch out.
    Sea Ray 21 SPX bow storage
    The storage compartments in the bow are tight to be sure. We’d recommend wearing the flotation devices rather than take up valuable space. Certainly an anchor will be stored here for starters.

    Step Right Up…

    Under the aft facing bow seat is a set of steps leading to the non-skid wrapping around the bow. In this manner, the SPX 210 OB can be easily boarded, or disembarked, from the bow. It’s also another way to enter the water…just launch right off the bow.

    Under the forward cushion are non-skid steps.

    The boat's layout provides seating for 8 people.
    Sea Ray 21 SPX
    Note that the swim platform is full beam and high off the water which is a new trend in sportboat design. This platform is covered with the optional SeaDek material which is both soft and non-skid. We like it.

    The Stern

    The stern features a good-sized, beam-width swim platform with room for gearing up for the water. Set high above the waterline, the platform has a recessed, four-rung boarding ladder and optional SeaDek padding is available.

    Sun Pad and Chaise Seating.

    Sea Ray took the traditional aft sun pad and added in a convertible transom seat. The forward section of the pad can be raised to create a reclining seat back, and it makes a good spot to relax and watch the kids play.

    The large molded swim platform melds into the sleek lines of the SPX 210 OB.
    Sea Ray 21 SPX transom seat
    The aft-facing transom seat will accommodate up to two across. Obviously the outboard version has an added comfort perk.
    Sea Ray 21 SPX sun pad storage
    With the sterndrive version, there will naturally be an engine under this sun pad/aft-facing seat. With the outboard version, there’s cavernous storage.

    The Cockpit

    A port side transom walkthrough

    eases the access into the cockpit. This walk-through then takes a slight turn to the diagonal before entering the cockpit. This is an unusual design feature as it does a surprisingly good job of adding space to the seating. Now, regardless of where one sits, there are no knees knocking and while the space remains social, there’s no crowded feel to the seating.Another hidden gem is that Sea Ray narrowed down the gunwales a bit and this, along with what is the widest beam in class, adds to the spacious feel of the cockpit.

    Sea Ray 21 SPX angled entry
    Here we can see the angled entry to the cockpit and the roominess that the layout provides.
    Sea Ray 21 SPX battery
    At the walkthrough is a hatch leading to storage that is shared with the battery. Notice the gutter surrounding the opening to the compartment and we can see the hose leading from the drain directly overboard.

    Further ahead is another storage compartment under the step to the cockpit.

    Clever Design.

    In the cockpit we find some creative solutions to the age-old problem facing sportboat designers; namely, should the seating be set up for running, partying or towing? Sea Ray's design team has come up with a surprisingly simple solution that allows the cockpit to fulfill all three requirements. This plays well into one of the original themes, which is configurability.

    A long bench seat to port

    offers room for sitting three-across. With three people sitting here, three aft and one in the swiveling captain's seat, 7 people can be accommodated in the cockpit for drinks, a picnic or just conversation. And all this without any feeling of being shoe-horned into place and everyone having plenty of “elbow” room.

    Shown here, the observer’s filler cushion installed to maximize seating when entertaining at anchor or at the dock.
    Sea Ray 21 SPX aft facing chaise
    The port lounge accommodates a wide variety of seating arrangements. Here is the aft facing chaise.

    Removing the filler cushion, stowing it under the aft seat and then moving the seatback ahead creates a forward facing companion seat. That seat back serves double duty also becoming a seat back for a spotter when towing.

    Sea Ray 21 SPX forward facing seat
    Here the port seating allows for the traditional forward facing seat. Seating just behind remains accessible.
    Sea Ray 21 SPX filler cushion
    The filler cushion had dedicated storage under the aft seat.
    Sea Ray 21 SPX seat back
    It’s easy to move the seatback from the aft position to the middle for more versatility.

    Yet a third variation

    on the portside seating is to have the removable vertical seat back at the aft end of the bench making a chaise lounge facing forward. A padded back rest forward on the port console allows a companion to do the same facing aft.

    Sea Ray 21 SPX chaise lounge
    Of course the seat also lends itself to a forward-facing chaise lounge.
    Sea Ray 21 SPX l shaped seating
    The L-shaped seating to starboard maximizes the boat's entertaining possibilities. The anodized black towing arch is part of the "Elevation Package" that includes a dash visor, SeaDek swim platform matting, ski mirror, Bimini, and racks for $4,633.

    More Seating.

    At the back of the cockpit is a very large L-shaped seating arrangement. Two people can face forward in the aft seat bench seat and two more can sit athwartships facing to port. Storage bins and a designated beverage cooler nook (to starboard) can be found below the cushions. Virtually no space has gone to waste in the SPX 210 OB.All told, in entertainment mode, 8 people can comfortably sit in this cockpit.

    Sea Ray 21 SPX carry on cooler
    Note the dedicated storage for the carry-on cooler under the starboard seating.

    The helm

    offers the captain a swivel bucket seat that adjusts fore and aft. Nestled behind a tinted glass, flat panel windshield, the driver has good views of the instrumentation that includes multifunction gauges, a power-assisted sport steering wheel and conventional side-mount engine controls.

    Sea Ray 21 SPX helm dash
    The optional Perfect Pass controller is situated in the helm’s dash for easy use.
    Sea Ray 21 SPX port console storage
    The port console storage is very deep and accessed from a side-mount door.

    Major Features

    • Fresh Sea Ray design focused on watersports
    • V6 sterndrive power with optional 4.5 L engine
    • Generous seating options
    • Full-beam width activity platform
    • Three distinct convenience packages available
    • Trailer included in base price


    The base price of the Sea Ray SPX 210 OB powered by optional the 200-hp Mercury Verado engine is $50,190. Downgrading to the smaller SPX 190 OB saves around $1,400, bring what would normally be the "base price" for most builders to $33,460.

    Sea Ray 21 SPX windshield
    Note that the driver is looking under the windshield frame and not at the windshield header, a common problem in boats in this class. Also, note the latch is at one end of the in-deck storage hatch, not in the middle where many builders put it thus requiring orangutan arms to reach it.

    Options to Consider

    Every boat owner has their own slightly different needs and desire, so by carefully looking over the option list and selecting only options that are necessary the price of the SPX 210 OB can be kept under $50,000.We are often asked by readers what we recommend for options, so here is how we would option out the boat for general sportboat use--

    4.5 L 250-hp MerCruiser Engine.

    We have tested this engine and we like it and think that it’s well worth the up charge over the 220-hp 4.3 L model.



    Canvas Package.

    Sea Ray's pricing on canvas is one of the best in class. Every boat needs some canvas, but this package has it all -- Bimini with front, side and aft curtains (this greatly increases the utility of the boat), cockpit cover, Tonneau cover and bag.



    Hull Side Color.

    Regular readers know that we think the hull color is worth whatever it costs to make the boat look its best and enhance pride of ownership. In this case, the price isn't bad for just colored hull sides.



    Comfort Package

    . This package includes a battery on/off switch (a necessity in our book), depth sounder, helm seat bolster (also something we think is necessary) and a snap-in carpet.



    Allsport Package

    , for the avid fisherman, including casting chairs, livewell, trolling motor, rod storage, battery charger.



    Elevation Package

    , leaning towards watersports including a sports tower, ski mirror and tower racks.



    Select Package

    , offering luxury on the water with two interior color options, upgraded upholstery, premium helm, LED lights and stainless steel upgrades.



    Automatic Engine Room Fire Suppression System.

    We are very careful about daily engine checks and being Boy Scout when re-fueling, nevertheless, this system in our option is just good, cheap, one-time insurance.



    Stainless Steel Component Upgrade.

    We hate to see weeping rust stains on hardware.



    Painted Tandem Axle Trailer with Dual Disc Brakes.

    We have to admit that this comes mostly under the heading of looking cool, the safety of the dual-axle disc breaks notwithstanding. Oh, there is nothing quite so good-looking as a boat with a colored hull on a tandem axle trailer with a matching paint job -- and why not at these prices?



    Total bill

    for having the Sea Ray 21 SPX "our way":



    Sea Ray 21 SPX running shot
    The SPX 210 model in this image has the optional "Full Monty" color treatment. $2,133.


    We are big supporters of small boats that combine functionality, usability, and good aesthetic styling and safety -- and it looks like the Sea Ray SPX 210 very much fits that description. Further, her options couldn't be more reasonably priced.

    Test Result Highlights

    • Top speed for the Sea Ray SPX 210 OB (2015-) is 46.5 mph (74.8 kph), burning 14.5 gallons per hour (gph) or 54.88 liters per hour (lph).
