Yamaha XLT 800 Review

The Yamaha XL Family

The Yamaha XL WaveRunner family debuted in 1998 when the manufacturer revealed the innovative XL 760.

This model was replaced by the more advanced XL 800 for the Millennium. This ski was rebranded to the XLT 800 and remained in production through 2004.

In a nutshell, production XL and XLT WaveRunners were as follows:

Let’s get down to the nitty-gritty and talk about the XLT 800 in detail!

Yamaha XLT 800 Hull and Top Deck

As the name suggests, the Yamaha XLT 800 was built on the “XLT” platform, which was an upgraded configuration of the original XL hull.

But it’s a lesser-known fact that the predecessor XL 800 also utilized the same platform and engine.

Yes, you read correctly, the XL 800 and the XLT 800 were basically the very same ski except for some cosmetic changes.

Regarding dimensions, this revamped XLT platform measured 124.4 inches in length, 48 inches in width, and 44.5 inches in height. This means that XLT WaveRunners were .4 inches longer and 1.2 inches narrower than their XL predecessors.

You can easily distinguish between the XL and XLT platforms since the latter featured a more modern, much sleeker top deck design.

The dry weight of the XLT 800 was 709 pounds, 17 pounds more than the XL 800.

It also came with a larger (18.5-gallon) fuel tank, a larger oil tank, and greater storage capacities including front storage, glovebox, and rear storage under the seat.

Thanks to its stable hull and roomy 3-rider seat, the XL 800 could easily accommodate three adult riders.

Because of this, the 800 was widely used for activities like family riding, PWC touring, tow sports, and fishing.

Yamaha XLT 800 Engine

Just like the hull and top deck, the engine of the XLT 800 was carried over from the XL 800 without any noticeable changes.

This power source was a 2-stroke, 784cc, reed-valve, twin-cylinder Yamaha marine engine that delivered 120hp at 7000 RPM.

The key features of this power mill included:

  • Bore x stroke: 80 x 78 mm
  • Compression ratio: 6.6:1
  • Digital CDI ignition
  • Reed valve intake system
  • Electric start
  • 2 x Mikuni BN44 carburetors
  • Oil injection system
  • Open-loop cooling system
  • NGK BR8HS spark plugs
This engine was paired with an axial-flow, single-stage pump, which came standard with a 5-blade impeller and a manual reverse gate.

The claimed fuel consumption of the XLT 800 was 12.9 gallons at WOT, so its 18.5-gallon fuel tank offered a cruising time of 1.4 hours.

You could expect the top speed of the ski to be in the ballpark of 50-55 mph depending on the external conditions and load.

Yamaha XLT 800 Features

The XLT 800 inherited its features from the XL 800, which were as follows:

Besides the above, it enjoyed a digital multifunction gauge, of which the features were as follows:
  • Speedometer
  • Tachometer
  • Fuel meter
  • Engine oil meter
  • Clock
  • Hour meter
  • Trip meter
  • Trip timer
  • Warning light
  • Display for PADLOC and direction of warning indicator
  • Battery warning indicator
  • Engine overheat warning indicator
  • Fuel warning indicator
  • Oil warning indicator

Yamaha XLT 800 Problems

Unlike the other classic 2-stroke WaveRunners, the XLT 800 had some common problems, including:

  • Falling power valves: The power valves of this ski were prone to loosening and falling off. In a worst-case scenario, they were sucked into the cylinders causing serious engine damage. This issue could be fixed by installing special clips on the power valves.
  • Oil lines: The oil lines of 2-stroke jet skis often cracked or fell off, which often resulted in an engine seizure. The only way to prevent these issues was to eliminate the oil system and switch to premix.
  • Crankshaft bearing: The crankshaft bearing also blew up on some XLT 800s. As one may expect this often ended in severe engine damage.
  • Heavy weight: The XLT 800 was much heavier than the smaller 700 and 760, but didn’t have the engine power of the triple engine of the 1200 models.
Therefore, if you are in the marketplace for a classic XL WaveRunner, you should steer clear of the XLT 800.

Instead, you may want to invest in an XL 1200 or XLT 1200. These skis are not only more powerful, but they also tend to be more reliable.
