2007-2009 Sea-Doo WAKE 155 Review

‘07-’09 Sea-Doo WAKE 155 Hull and Top Deck

The first Sea-Doo WAKE was introduced in 2004 under the name of Sea-Doo GTX WAKE. As the name suggests, this family was designed with wakeboarders in mind.

Unlike its small 2-stroke predecessors, these modern boat-like jet skis could be used for a variety of water activities, and wakeboarding was no exception.

The very first GTX WAKE was manufactured unchanged from 2004 through 2006 and was redesigned for 2007.

Just like its predecessor, the new 2007 WAKE 155 was also built on the popular GTX platform and utilized the 155 HP Rotax engine. Because of this, the WAKE 155 was often referred to as GTX WAKE 155 as well.

In terms of dimensions, the ski measured 130.3 inches in length 48 in width, and 47.2 inches in height.

Due to its extra features, the dry weight of the WAKE 155 was 840 pounds, 45 pounds more than the base GTX 155.

Its body enclosed a 15.9-gallon fuel tank, a rear storage basket, a glovebox, and a standard bow storage. The latter featured a sealed cap which made the storage bin waterproof.

For 2010, the WAKE 155 was completely redesigned and returned with a refreshed design.

 ‘07-’09 Sea-Doo WAKE 155 Engine and Propulsion

The power source of the ‘07-’09 Sea-Doo WAKE 155 was the proven 4-stroke, 1494cc, SOHC, 3-cylinder Rotax 4-TEC engine rated at 155 HP. This unit was carried over from the GTX WAKE without any changes.

This engine was the first 4-stroke Sea-Doo power source, and it was offered in three different output variants, 130, 155, and 215 HP.

The key features of the 2007-2009 Sea-Doo WAKE 155 engine were as follows:

  • 4-stroke, 3-cylinder architecture
  • Naturally-aspirated, 52mm throttle body
  • 12 valves (4 per cylinder) with hydraulic lifters
  • Single Over Head Camshaft (SOHC)
  • Compression ratio: 10.6:1
  • Performance: 155 HP
  • Water-cooled exhaust system
  • Dry sump lubrication system
  • Digital inductive ignition
  • Closed-loop cooling system
  • Electric starter
Thanks to its 4-stroke configuration and advanced features, the Rotax 4-TEC engine offered a smooth power delivery and plenty of torque.

This engine was paired with an axial-flow, single-stage jet pump, housing a stainless steel impeller, and a 10-vane stator.

 ‘07-’09 Sea-Doo WAKE 155 Features

The ‘07-’09 Sea-Doo WAKE 155 came with many advanced features, including:

  • Information Center Gauge
  • DESS post (engine cut-off switch)
  • Padded handlebar cover
  • Handlebar-mounted start/stop buttons
  • OPAS fins
  • Front storage compartment
  • Glovebox
  • Rear storage basket
  • Fire extinguisher holder
  • Mechanical reverse
  • 3-rider seat
  • Rear seat latch
  • Bilge drain plugs
  • Thumb throttle lever
  • Tow hook
  • Front and rear eyelets
  • Dual mirrors
  • Rear grab handle
  • Sponsons
  • Deck mats
Besides the above, the WAKE 155 was also equipped with some unique wakeboard intended features, including:

  • VTS – Variable Trim System
  • Wakeboard rack
  • Ski/wakeboard post
  • Ballast tank
Let’s get down to the nitty-gritty and talk about each in detail!

VTS – Variable Trim System

The WAKE 155 was one of the few Sea-Doos in the 2000s that came standard with the innovative Variable Trim System (VTS).This system was designed to change the trim; the vertical angle of the jet nozzle.

It was a game changer for the operator since towing a wakeboarder completely changed the forces acting on the Sea-Doo.

Thanks to the VTS, these changes could be compensated for by adjusting the trim.

Over the years, the VTS system has become more prevalent on other Sea-Doo models as well.

Sea-Doo WAKE Wakeboard Rack

Let’s face it, Sea-Doos offer very limited space for wakeboard gear. The board is especially difficult to place on the small deck.

This is where Sea-Doo’s wakeboard rack comes into play. Mounted on the side of the footwell, this rack can carry a wakeboard or a wakeskate with ease.

Keeping safety in mind, it features straps to keep the board secure.

This useful rack became standard equipment on each Sea-Doo WAKE model.

Sea-Doo Wakeboard Post

The Sea-Doo Wakeboard Post is a mini retractable wakeboard pylon mounted behind the rear seat.

The key advantage of this feature is that it provides a higher connection point for the tow rope.

It is not only more convenient for the wakeboarder but also reduces the chances of the jet pump sucking the rope in.What’s more, it’s equipped with two folding handrails for the observer.

When it’s not in use, the post can be retracted under the rear grab handle.

Like the rack, the Wakeboard Post also found its way to every Sea-Doo WAKE model produced since 2004.

Sea-Doo Ballast Tank

The Sea-Doo Ballast Tanks were two wedge-shaped plastic tanks that could be mounted on the rear platform. They also expanded into the rear portion of the footwells.

These removable tanks could be filled with water through two quick connectors. Their total capacity was 200 pounds.

The main idea behind this setup was to enhance the size of the wake.

Unfortunately, these ballast tanks never became popular, so they were only offered from 2006 through 2009.

’07-’09 Sea-Doo Wake 155 Gauge

The information center gauge of the WAKE 155 also had many useful functions, which were as follows:

  • Speedometer
  • Tachometer
  • Fuel level
  • Information display
  • Compass
  • Hour meter
  • Message display
  • Water temperature display
  • VTS position indicator
  • Indicator lights

 ‘07-’09 Sea-Doo WAKE 155 Performance

The WAKE 155 instantly became popular among wakeboarders, and with good reason.

This machine had many advantages over a regular wakeboard boat, which were as follows:

What’s more, the WAKE 155 was very fast, so it could reach the best wakeboard spots within a short period of time.

The top speed of the ‘07-’09 Sea-Doo WAKE 155 was 55-56 mph in stock condition.

‘07-’09 Sea-Doo WAKE 155 Problems

Although the WAKE 155 was known as a bulletproof Sea-Doo, it had some minor flaws, including:

  • Awkward thumb throttle
  • OPAS malfunctions
  • Lack of a brake system
Believe it or not, the ’07-’09 WAKE 155 was still being manufactured with an outdated thumb throttle.

Unlike modern finger levers, this thumb throttle lever caused a lot of hand fatigue and ensured less precise throttle handling.

Another flaw of the WAKE 155 was its deflective OPAS rudders. This system was designed to be an off-throttle steering assist system, but it often came into operation when it shouldn’t.

Fortunately, the OPAS rudders could be easily removed.

It’s also good to know that the ’07-’09 WAKE 155 was manufactured without a brake system.

This was no surprise since Sea-Doo’s iBR brake and reverse system wasn’t released until it appeared on the flagship 2009 Sea-Doo models.
