Sea-Doo RXT 215 Review

Sea-Doo has always been known for its large fleet of versatile PWCs.

Its deservedly-popular performance series (including the XP/RXP, and HX models) offered extreme power and outstanding cornering abilities.

On the other hand, they were too nimble and had limited capacities. Riding with a passenger on these small Sea-Doos was often hard to impossible.

Besides these machines, 3-seater runabout Sea-Doos were popular among families, but they lacked the lively attitude of their performance brothers.

So, many buyers were looking for a ski with a high-performance engine/features and reasonable capacities.

Sea-Doo grabbed the opportunity and designed a “race-inspired” 3-seater runabout, the 2004 RXP 215 (a.k.a. RXP 4-TEC SC). To achieve the best of both worlds, this new ski was built on the stable and comfortable 3-seater GTX platform but utilized a supercharged 215 HP engine as well as many race-oriented features.

Therefore, it’s safe to say that the Sea-Doo RXT was actually a GTX on steroids! It was tuned for a sporty riding experience rather than comfort.

The RXT line is known for its rich history, as over the decades it underwent many different generations, including:
  • 2005 – 2010: RXT 215
  • 2008 – 2009: RXT-X 255
  • 2009: RXT-X iS 255
  • 2010: RXT iS 260
  • 2010 –2015: RXT-X 260
  • 2010 – 2012: RXT iS 260
  • 2011 – 2017: RXT 260
  • 2012: RXT 260 RS
  • 2011 – 2016: RXT-X aS 260
  • 2012 – 2015: RXT 260
  • 2015: RXT-X 260 RS
  • 2017 – 2019: RXT 230
  • 2016 – RXT-X 300
The first model in this breed was the RXT 215, powered by the supercharged and intercooled 215 HP Rotax 1503 marine engine. The key features of this power source were as follows:

  • 1494cc, 3 cylinder in-line
  • Rotax Multipoint Fuel Injection
  • Induction type: supercharger with intercooler
  • 12 valves (4 valves per cylinder) – SOHC
  • Dry sump oil injection system
  • Closed-loop cooling system
  • NGK DCPR8E spark plugs (x3)
  • Electric starter
This engine featured titanium valves and a big bore configuration, meaning that it came with short-stroke (63.4mm) and big-bore (100mm) cylinders. (You can find similar engines in 4-cylinder sportbikes.)

The shortened piston travel put less wear and tear on the engine’s internals, resulting in more durability and reliability.

The RXT shared this power source with the 2-seater RXP 215; both models produced an amazing 215 HP at 8,000 RPM.

The engine power was 30% greater than that of any of its rivals’, making these performance Sea-Doos the most powerful personal watercraft of that time.

Sea-Doo had borrowed the plastic engine cover from Honda AquaTraxs. This cover hid a large portion of the engine, ensuring a clean look.

The propulsion system of the RXT was the proven axial-flow, single-stage BRP Formula pump, featuring a full aluminum pump housing and a stainless-steel 4-blade impeller.This jet pump and engine were planted in a GTX hull, measuring 130 inches in length, 48 inches in width, and 44 inches in height. Yes, you read correctly; the RXT used exactly the same hull as the GTX line.

(The 2-seater RXP 215 was built on a modified GTI platform, which was only 121 inches long, 47 inches wide, and 41 inches high.)

This entirely new GTX/RXT platform was specifically engineered for the 4-stroke 1503 Rotax engine. It debuted on the 2002 GTX 4-TEC 155 and was carried over to many GTX, RXT, and WAKE models.

This all-new hull was 6 inches longer and offered much better stability than its predecessor. Also, it came with a deep-V design as its depth was increased to 22.5 degrees from 17.5 degrees.

The innovative top deck also featured eye-catching curved lines and other details. What’s more, it housed three storage compartments, including a glovebox, an under-seat storage box (with a spare spark plug holder), and a roomy bow storage.

The total storage capacity of the RXP 215 was a whopping 52.5 gallons. In contrast, “old” GTX models came with a storage capacity of 13.2 gallons, while the RXP 215 offered only 10.7 gallons

The weight capacity of the ski was 600 pounds, so it could carry three riders safely and legally.

As far as features and accessories, the RXT shared many with the flagship GTX and RXP, including the 15.3-gallon fuel tank, closed-loop cooling system, D.E.S.S. security system, and O.P.A.S. steering assist.

To be more precise, the features of the 2005 Sea-Doo RXT 215 were as follows:

  • Handlebar-mounted start/stop button
  • Handlebar-mounted function buttons
  • Large front storage
  • Glove box
  • Under-seat storage tray
  • Electric start
  • Tether cord
  • 2 gauges (speedometer, tachometer)
  • Fender cleats
  • Off-Power Assisted Steering (OPAS)
  • Overheating warning device
  • Bow and stern eyes
  • Ski tow eye
  • Bilge drain plugs
  • Sponsons
  • Rear grab handle
  • Manual reverse
  • Reboarding step
  • Large, 2-piece seat with a seat strap
  • DESS security system
Its large dashboard featured an analog speedometer, an analog tachometer, and a 19-function info display. The Gauge Functions of this info panel included:
  • Digital Tachometer: Indicates the revolution per minute (RPM) of the engine.
  • Digital Speedometer: Indicates the speed of the watercraft in miles per hour (MPH) and kilometers per hour (km/h).
  • Depth Gauge (if so equipped): It continuously displays the water depth under the hull within 0 to 50 meters (0 to 170 feet).
  • Compass: Displays the cardinal points to indicate the orientation of the watercraft.
  • Average Speed: The information center approximately calculates and displays the average speed (AV KM/H or AV MPH) of the watercraft since the last engine start.
  • Distance: (KM or MILES) The information center approximately calculates the distance based on the operation time and the watercraft speed and displays the result in kilometers (KM) or miles (MILES).
  • Hourmeter: Displays the time in hours of the watercraft usage (HOUR).
  • Water Temperature: Displays the water temperature of the water surface (L TEMP) in degrees Celsius (C) or Fahrenheit (F).
  • Exterior Temperature (if so equipped): Displays the exterior air temperature (E TEMP) in degrees Celsius (C) or Fahrenheit (F).
  • Trip Hour Meter: (TRIPMTR) Allows to measure an interval of time in hours and minutes (hh:mm).
Riding experience?

Thanks to its stable platform, the RXT 215 offered predictable and smooth rides even with passengers.

In the early 2000s, the RXT was arguably among the most stable 3-seater PWCs in the marketplace.

At the same time, it could easily reach a top speed of 68 mph in stock condition. With some performance modifications, its top speed could be increased up to 70-72 mph.

It also provided an arm-stretching acceleration as it could do the 0-30 mph run in 1.8 seconds and the 0-60 mph in 5.5 seconds.

However, the large heavy RXT (869 lbs!) was less lively and nimble than the 2-seater RXP. While the latter shined on the racecourse, the RXT was great for thrilling adrenaline rushes and touring.

Its remarkable capacities made the RXT 215 instantly popular among buyers who didn’t want to compromise between performance and comfort.

The RXP 2015 offered both under one roof!

Sea-Doo RXT 215 Problems

Although it was an amazing watercraft in its time, the RXT 215 had some definite drawbacks.  Let’s take a close look at each!

Thumb Throttle

One of the few drawbacks of the Sea-Doo RXT 215 was its outdated thumb-throttle lever.

Unlike modern trigger levers, this thumb throttle was mounted in an awkward position offering zero comfort on long rides.

This is why the more advanced RXP-X and RXT-X models came already equipped with a finger throttle.

Lack of Trim System

What’s more, believe it or not, Sea-Doo marketed the RXT 215 without VTS (Variable Trim System).

This innovative feature was only available on flagship models like the GTX SC and the RXP 215.

Ceramic Supercharger Washers

The biggest problem with the RXT 215 was arguably its ceramic supercharger washers.

Like in any other supercharged Sea-Doo in the mid-2000s, the supercharger of the RXT 215 was manufactured with ceramic washers.

Unfortunately, these deflective washers were prone to breaking after a short period. The debris easily got into the engine, causing major damage to its internals.

Due to this risk, these ceramic washers in the 2005-2008 RXT 215 models had to be replaced with metal ones.

Since early 2008, supercharged Sea-Doos have come with metal washers from the factory.

Despite this, every Sea-Doo supercharger required attention and periodic rebuilds, regardless of the production year.

RXT 215 O.P.A.S. Issues

Another common complaint against the RXT 215 was its O.P.A.S. (Off-Throttle Assisted Steering) issues.Although O.P.A.S. was a revolutionary idea, it automatically activated on choppy waters. This is because the fluctuating pressure in the pump often fouled its sensors.

Because of this, many owners removed the O.P.A.S. fins from their RXTs.
