Home/News/1993-1999 Sea-Doo SPX Specs and Review [Video]

Sea-Doo marketed its widely popular SPX family from 1992 through 1999. Surprisingly, each Sea-Doo SPX model was almost identical to the previous year’s XP.

If you want to learn all about this popular vintage jet ski, this post is for you.

We at JetDrift have compiled all you need to know into this Sea-Doo SPX review!

Sea-Doo SPX Review

It’s safe to say that Sea-Doo’s XP line was one of the most successful PWC families in history.

The first XP was actually a dual-carb SP, but this model quickly became the flagship model in Sea-Doo’s fleet.

To get the most out of this model, the Canadian manufacturer virtually marketed two XPs each year. The all-new machine was always labeled as XP, while the previous year’s XP was also offered under the brand name SPX. (Except 1998-1999 when the models were the same as the 1996 XP.)

Sea-Doo continued this trend throughout the ’90s before it dropped the SPX in 1999.

Since we’ve posted a detailed review for each XP model, it wouldn’t make much sense to write the same reviews again for the SPX line.

Instead, we’ve linked our XP reviews below. If you want to know more about any of these models, don’t hesitate to follow these links:

1993 SPX 580 = 1992 XP 580 (587)

1994 SPX 650 = 1993 XP 650 (657)

1995 SPX 650x = 1994 XP 650x (657x)

1996 SPX 720 = 1995 XP 720 (717)

1997-99 SPX 800 = 1996 XP 800 (787)

1993 Sea-Doo SPX 580 Review

The first Sea-Doo SPX 580 made its debut for the 1993 model year and was almost identical to the 1992 Sea-Doo XP.

This machine still had the outdated 1st generation Sea-Doo hull, while the power source on the ski was the upgraded “White” Rotax 587 engine.

This 580cc, oil-injected, 2-stroke twin marine engine cranked out 56 HP and ensured a top speed of 45 mph under ideal conditions.

The ski’s weight was 5 pounds more than the original ’92 XP, as it weighed 370 pounds.

1994 Sea-Doo SPX 650 Review

The 1994 Sea-Doo SPX 650 (a.k.a. SPX 657) was actually identical to the 1993 XP 650 (or 657).

This machine was built on the rounded, 2nd generation hull and housed a dual-carb Rotax 657 engine. This 650cc, 2-stroke twin featured an oil injection system, CDI ignition, open-loop cooling system and was rated at 70 HP.

Thanks to this power source, the top speed of a stock 1994 SPX was about 50 mph.

Unfortunately, this SPX was 24 pounds heavier than its XP-equivalent for some reason.

1995 Sea-Doo SPX 650x Review

Like the 1994 model, the 1995 SPX 650x (a.k.a. SPX 657x) still had the 2nd generation hull, while the all-new 1995 XP was built on the innovative X4 platform.

The 1995 SPX was a rebranded 1994 XP featuring a dual-carb Rotax 657x engine rated at 80 HP.

Are you wondering what the differences are between the Rotax 657 and 657x engines?

In a nutshell, the major improvements on the 657x engine were as follows:

  • Tuned exhaust system with a slightly larger expansion chamber
  • Two Mikuni BN-38I carburetors (the base Rotax 657 utilized two Mikuni BN-38s)
  • Full circle counterweights
  • Improved timing

Thanks to these advanced features, the 657x offered a whopping 80 HP, about 10 HP more than its predecessor.

This power source propelled the 1995 SPX up to 50 mph on good days.

1996 Sea-Doo SPX 720 Review

For 1996 the SPX saw some major changes, as its engine was identical to the 1995 XP. This model was known as the 1996 SPX 720 as well as the SPX 717.

Surprisingly, this ski was still built on the 2nd generation “old” Sea-Doo hull, even though the 1995 XP utilized the widely-popular X4 hull.

The power source of the 1996 SPX was the proven Rotax 717 marine engine. The latter was a 718cc, an oil-injected 2-stroke twin was rated at 85 HP. Although this unit didn’t crank out significantly more power than the 657x, it ensured a better bottom end.

Power was delivered towards an upgraded Bombardier Formula jet pump featuring a 4-inch spacer on its front. The main idea behind this spacer was to increase water volume, which resulted in more thrust.

Unfortunately, this adjustment offered a poorer riding experience on choppy waters, as the jet pump needed more time to fill itself with water after unhooking.

The top speed of the 1996 SPX 720 was about 50 mph, but it accelerated more aggressively than its predecessor.

1997-1999 Sea-Doo SPX 800 Review

There’s no question that the most desirable SPXs were the 1997-1999 models, which were almost identical to the 1996 Sea-Doo XP.

This is when the SPX line finally got the extremely popular X4 platform, measuring 100 inches in length, 41.5 inches in width, and 36.2 inches in height.

This hull was narrowed at the bow and extended towards the rear end of the ski. It was also equipped with a tuneable ride plate, well-designed sponsons, and removable trim tabs for better stability and handling.

While the 1997-1999 XPs came with the new parabolic “hourglass shape” hull, the SPXs were still built on this X4 platform during these years.

The engine on the new SPX 800 (a.k.a SPX 787) was the high-performance Rotax 787 R.A.V.E. power mill rated at 110 HP. This unit was a 782cc, 2-stroke, 2-cylinder marine engine featuring an oil injection system, CDI ignition, open-loop cooling system, and the innovative R.A.V.E exhaust power valves.

The key advantage of these SPXs was that the design flaws of 1996’s Rotax 787 engine had already been corrected for these years.

For example, in the ’96 XP, the flywheel and the counterbalancer shaft were prone to breaking into pieces, causing major engine damage. This is because these parts were not correctly heat treated like they were in the ’97-’99 models.

What’s more, the R.A.V.E. valves also saw some upgrades for the ’97 season. In the ‘96 models, these valves often snapped off, damaging the cylinder head and pistons.

Besides these major components, many smaller units were upgraded for 1997, like the ignition, aluminum water regulator, and the exhaust system.

Thanks to these upgrades, the ’97-’99 SPX models were far more reliable and durable than their 1996 XP predecessor. On top of that, the 1998 SPX was slightly lighter for some reason, as it weighed only 428 pounds while the ’96 XP weighed 434 pounds.

Therefore, if you are looking for a vintage Sea-Doo SPX or XP for sale, keep in mind that the 1997-1999 SPXs are considered a better deal than the equivalent ’96 XP.

To the greatest regret of many fans, the SPX never got the most powerful Rotax 591 power source and the parabolic Sea-Doo hull, as the manufacturer reserved them for the flagship XP models.

The X4-hulled SPX with the 787 R.A.V.E. engine was marketed from 1997 through 1999.

After this model year, the SPX model permanently disappeared from the market, as did the X4 hull.
