2005-2008 Yamaha FX Review

Yamaha FX Hull and Top Deck

In 2002, Yamaha phased out its 2-stroke XLT series (XLT 800, XLT 1200) with the all-new 4-stroke FX line.

The first model in this breed was the FX 140, which was followed by the FX Cruiser (140) in 2003.

The more powerful “big-bore” configurations of these skis were the FX HO and FX Cruiser HO, both of which were released in 2004.

For the 2005 season, the FX 140 was rebranded to FX and upgraded with some new features like a new color scheme, a revamped multifunction gauge, and a watertight compartment on the top deck. Other features, including the body, engine, and pump were carried over from the FX 140 without any significant changes.

This means that these skis shared the same FX platform that debuted in 2002 and remained unchanged until the early 2010s.

This stepped deep-V hull was made of standard Sheet Moulding Compound (SMC) and measured 131.5 inches in length, 48.4 inches in width, and 45.7 inches in height.

Thanks to its impressive dimensions, deep keel, and heavy weight the FX ensured fairly dry rides and an outstanding rough water performance.

Riders also appreciated FX’s spacious top deck and its overall weight capacity of 530 pounds.

Besides the 18.5-gallon fuel tank, the ski had four separate storage units, including a 2.6-gallon glovebox, 19.8-gallon bow storage, 4-gallon under-seat storage, and a tiny 0.7-gallon watertight compartment located between the handlebars and dashboard.

Yamaha FX Engine

The 2002-2008 FX WaveRunners were marketed with two MR1 engine options, including the “big-bore” 1052cc, 160hp and “small-bore” 998cc, 140hp configurations.

Both of these units were heavily redesigned versions of Yamaha’s high-performance R1 motorcycle engine.

This is why they were so revvy!

While FX HOs enjoyed the more powerful 160hp engine, the base FX and FX Cruiser came standard with the smaller, 140hp variant. In terms of specifications, this unit was a 4-stroke, 998cc, inline-4 Yamaha marine engine.

The key features of this power mill included:

  • Bore x stroke: 74 x 58 mm
  • Compression ratio: 11.4:1
  • Dry sump lubrication system
  • TCI ignition system
  • Fuel injection system
  • Electric start
  • Open-loop cooling system
  • NGK CR9EB spark plugs
This engine was completed with a 155mm jet pump featuring a manual reverse and manual trim system.

Regarding performance, the FX topped out at 55-57 mph (on GPS) while burning 11.6 gph.

Thanks to its 18.5-gallon fuel tank, the cruising range of this ski was a remarkable 1.6 hours.
