1995 Sea-Doo GTX 650 Review

The history of 3-seater Sea-Doos started with the base GS 580 introduced in 1990.

This ski was built on a flat-bottom hull and utilized a “Yellow” Rotax 587 engine. This model was then carried over for the 1991 season without any significant changes.

By 1992, the GT was rebranded to GTS, and remained the entry-level 3-seater PWC in Sea-Doo’s fleet for many years.

Over the years, the 2-stroke Sea-Doo GTX family underwent many upgrades and generations, including:

In the 1993 model year, the GTX 580 made its debut followed by the GTX 650 in 1994. These models already had the new “straked” hull design, ensuring better handling and stability.

The 1995 Sea-Doo GTX 650 (a.k.a. Sea-Doo GTX 657x) inherited this straked GS-style platform, but it had a more advanced power source.

Unlike the ’94 GTX 650, which had the base Rotax 657 (70 HP), the ’95 model came with the revamped Rotax 657x engine. This upgraded 2-stroke 650cc twin power source debuted on the 1994 Sea-Doo XP.

Major upgrades on the Rotax 657x engine compared to the base 657 were as follows:

  • Tuned exhaust system with a slightly larger expansion chamber
  • Two Mikuni BN-38I carburetors (the base 657 had two Mikuni BN-38s)
  • Full circle counterweights
  • Improved timing
Thanks to these advanced features, the Rotax 657x offered 80 HP, 10 HP more than its predecessor. With this more powerful engine, the top speed of the 1995 GTX 650 was about 45 mph.

Except for this engine upgrade and the sleeker mirrors, the 1995 Sea-Doo GTX 650 was almost identical to the ’94 model.

The ski measured 119 inches in length, 46.9 inches in width, and 47.4 inches in height, and it had a dry weight of 484 pounds.

Standard features of the 1995 Sea-Doo GTX 650 included:

  • Electric start
  • Handlebar-mounted engine stop button
  • Tether cord
  • 8.7-gallon fuel tank
  • 95 oz. oil reservoir
  • Fuel tank reserve
  • Deck mats
  • Overheating warning device
  • Manual reverse
  • Removable storage compartment
  • Rear grab handle
  • Rear vent grill
  • Docking eyelets
  • Speedometer
  • Bile drain plugs
  • Fuel level gauge (with low-oil warning light)
  • Electric fuel level gauge
  • Injection oil low-level warning device
  • Water tank trap drains
  • Dual mirrors
  • Tool kit
A unique “Touring Seat” was also offered on GTX and GTS models as an option. Its bolted design provided great support for riders’ backs, resulting in higher comfort and better handling.

Due to its design, this seat offered comfortable rides for only two people, whereas the standard “bench-like” seat could accommodate three riders.

Although the GTX had a load limit of 496 pounds and was rated for one operator and two passengers, with three adult people it became very tippy. Therefore, this Sea-Doo was only recommended for two adult riders.

By 1996, Sea-Doo had replaced the GTX 650 with the new, more powerful GTX 800.
