1997-2000 Yamaha GP 760 Review and Specs [Video]

The GP 760 and the more powerful GP 1200 were the first members of the extremely popular GP WaveRunner family. These skis shared the same first-generation GP hull and housed high-performance 2-stroke engines. In 1998, the GP series was completed with the power-valved GP 800.

If you want to find out more about this 2-stroke performance WaveRunner, this post is for you.

Yamaha GP 760 Review

The Yamaha GP Series

In 1997, Yamaha released its performance GP line, including the GP 760 and the GP 1200.

These skis were intended to compete with sporty Sea-Doo XPs like the XP 800 and the XP Limited 951.

Over the years, the GP series was expanded with several new models, including:

Let’s talk about the smaller machine in this breed, the entry-level GP 760 in detail!

Yamaha GP 760 Hull and Top Deck

Just like the GP 1200, the GP 760 was also built on the first-generation GP hull, which was engineered with hardcore riding and PWC racing in mind.

It shared some DNA with the 3-seater XL platform, but it was significantly smaller and lighter. Both of these hulls and their top decks were made of Sheet Moulding Compound (SMC).

In terms of dimensions, the semi-V GP platform measured 112.6 inches in length, 44.1 inches in width, and 38.2 inches in height.

In contrast, 3-seater XLs were 11.4 inches longer, 5.1 inches wider, and 5.1 taller, all of which were not small differences.

The dry weight of the GP 760 was 470-474 pounds depending on the year, while its closest relative, the XL 760 weighed 551 pounds.

Thanks to its lighter weight and lower center of gravity, the GP 760 was more nimble and sportier than its 3-seater counterpart.

Regarding capacities, the GP 760 could carry two riders, 13.2 gallons of fuel, 1.06 gallons of oil, and 10.26 gallons of gear.

Its spacious top deck enclosed three separate storage units, including a 4.4-gallon removable bow storage bucket, a 5.6-gallon seat storage compartment, and a tiny 0.26-gallon glovebox.

Yamaha GP 760 Engine

The GP 760 shared its high-performance engine with the XL 760. This unit was a 2-stroke, 754cc, reed-valve, twin-carb, non-powervalved, twin rated at 90hp at 6,350 RPM.

This engine was designed with many advanced technologies, including:

  • Digital CDI ignition
  • Reed valve intake system
  • Electric start
  • Dual Mikuni BN44 carbs
  • Oil injection system
  • Open-loop cooling system
  • NGK BR8HS spark plugs

Unlike its 800 successor, the 760 engine lacked power valves, which ensured higher reliability and durability.

The GP 760 shared its axial-flow, single-stage jet pump with the XL 760, but lacked the manual reverse that came standard on XLs.

Yamaha GP 760 Top Speed and Performance

Yamaha GPs were considered to be sportbikes of the water, and with good reason. The top speed of the GP 760 was a remarkable 53-54 mph, 10 mph more than the 3-seater XL 760.

Even though the GP 760 generated 45hp less than the high-end GP 1200, its power was more than enough for the average jet ski enthusiast.

According to its operator’s manual, the claimed fuel consumption of the GP 760 was 10 gph at WOT. The ski came standard with a 13.2-gallon fuel tank that offered a cruising range of 1.3 hours.

When it comes to the riding experience, this PWC was easy to control thanks to its innovative semi-V hull design, advanced propulsion system, and high-performing adjustable sponsons.

It was capable of high wave jumps and various sit-down tricks.

Even though the GP 760 was rated for two people, it was mainly recommended for solo riders. With an adult passenger onboard the ski became much slower and more unstable.

Unfortunately, the GP 760 was also prone to porpoising due to its faulty weight distribution.

Yamaha GP 760 Features

The Yamaha GP 760 came standard with many innovative features, which were as follows:

  • Front storage compartment (4.4 US gal)
  • Seat storage compartment (5.6 US gal)
  • Glove compartment (0.26 US gal)
  • Fire extinguisher container
  • Manual trim
  • Deck mats
  • Bow and stern eyes

  • Rope holes
  • Rear grab handle
  • Fuel cock knob
  • Ski tow eye
  • Yamaha Adjustable Sponsons (Y.A.S.)
  • Finger throttle lever
  • Cooling water pilot outlet
  • Visibility spout

Besides the above, the FX HO came standard with a multifunction gauge, of which the features included:

  • Digital speedometer
  • Tachometer
  • Fuel level meter
  • Engine oil level meter
  • Clock
  • Hour meter
  • Trip meter
  • Trip timer
  • Warning lamp (LED)
  • Display for (Programmable digital locking ignition (PADLOC)
  • Warning indicators

Yamaha GP 760 Problems

It’s safe to say that the GP 760 was one of the most popular 2-stroke WaveRunners ever built. Despite this, it had some common problems, which were as follows:

  • Lack of reverse: Many riders agreed that one of the biggest drawbacks of the GP 760 was the lack of a reverse system. Unlike the GPs, 3-seater XL WaveRunners came standard with reverse from 1997 onwards.
  • SMC hull: The hull and the top deck of the GP 760 were made of sheet moulded compound (SMC). This special material was much harder to repair than standard fiberglass.
  • Oil system issues: The oil lines of 2-stroke GPs aged over time, which often caused an engine seizure. To prevent these issues, the oil system of these skis had to be inspected and maintained regularly. However, the safest solution was to eliminate the oil system and pre-mix the fuel by hand.
  • Battery discharging: The main ground on these skis was mounted to the bottom of the engine. This spot was not only hard to reach but was quite a wet environment for the ground. Because of this, the negative battery lead had to be disconnected and the battery hooked up on a trickle charge when the ski was stored. This trick helped to prevent battery discharging issues, which was a common issue on the GP 760.
  • Cold start issues: Many 2-stroke PWCs were hard to cold start and the GP 760 was no exception. Dripping a little premix into the spark plug holes or spraying starter fluid into the air intake before the start typically made the process easier.
  • Porpoising: Early GPs were prone to porpoising due to their poor weight distribution. This issue could be fixed by installing some weight into the hull or upgrading the ski with an aftermarket ride plate and intake grate.
