Yamaha GP760 and GP800 Review
The very first GP model, the Yamaha GP760 was released in 1997. It had the same hull and features as it’s brother, the GP1200.
The only difference was that the GP1200 had a more powerful engine, and was heavier of course.
The GP760 offered a really fun ride and easy control due to its lightweight semi V-shaped hull. The adjustable, racing-style sponsons also contributed to its stability.
Even if it wasn’t as sporty as a stand-up, an experienced rider could perform some really good tricks on this sit-down WaveRunner. According to many owners, wave jumping was always a lot of fun on these small GPs!
They offered legal rides for 2 people. But let’s face it, riding with passengers on these PWCs is not very good. Why?
Becasue with two adult riders they easily become unstable and tippy due to their small, flatter hulls.
Being realistic, the GPs were fine for one adult and a little child. More load made them too unstable and uncomfortable.
It should also be mentioned that as the GP760 and GP800 were powered with relatiely smaller engines, a passenger slowed them down significantly.
Becasue of these issues, the GP series wasn’t considered to be great family-WaveRunners.
GP760 and GP800 Porpoising Issues
Let’s be honest, every PWC has its strengths and weaknesses, and GPs are no exception.
Probably the biggest problem with the Yamaha GP800 is the porpoising.
Porpoising is when the WaveRunner continuously bounces up and down in porpoise-like movements. This problem is actually caused by a design defect in the hull.
Although the GP series was equipped with Yamaha’s QSTS (Quick Shift Trim System), it could not completely eliminate this effect.
Because of this, many owners equipped their crafts with trim tabs, which usually made a huge difference.
Beyond trim tabs, aftermarket intake grates, ride plates, and sponsons may also help to eliminate porpoising on the Yamaha GP800 and GP760.
But keep in mind, that even if these modifications help a lot, they cannot completely eliminate this problem.
But in 2000, Yamaha introduced the GP1200R, and two years later the new GP800R. These models came with completely new hull design, which was much better.
Let’s take a closer look at this model as well!
Yamaha GP800R Review
Are you wondering what the differences are between the GP760, GP800, and GP800R?
First things first, the GP760 and the GP800 were the very first GP models. They shared the same hull with the GP1200, but had less powerful, 2-cylinder engines. (GP760: 90HP, GP800: 120HP)
In 2002, Yamaha released the GP800R. This model was powered with GP800’s 120HP engine, but shared the hull with the GP1200R.
Put simply, the GP1200R replaced the GP1200 in 2000, while two years later the GP800R replaced the GP800.
Just like their predecessors, both R model got the same hull and features, but with different engine options. If you would like to learn more about this hull design and the GP1200R in general, don’t miss our GP1200 vs. GP1200R comparison post!
Here, in the next section we will go though the GP760 and GP800 specs and performance.
Yamaha GP760 and GP800 Specs
Since Yamaha has released many different GP WaveRunners over the years, the variety of models may confuse you. For a better understanding, we’ve compiled all of these models with their specs into this chart:
|Model||Year||HP||Power to weight ratio|
Don’t forget that the GP1800R HO was named as VXR in the first years. We can say that the performance of the GP WaveRunners improved greatly over time.
Let’s drill into these performance numbers deeper!
Yamaha GP760 & GP800 Top Speed and Performance
Aside from the GP760, the other GP models also don’t fail when it comes to performance. As we’ve already discussed, the 760 was released with the same hull as the GP1200.
The main difference was that the GP760’s engine is a 745cc, 2-cylider, 2-stoke power plant. In spite of the lower displacement and the 2-cylinders, the Yamaha GP760 produces no less than 90HP.
This performance and the lightweight hull boils down to a 0.19 HP/pounds power-to-weight ratio.
As you can assume, this model offers a lower top speed compared to its brothers. But surprisingly, the Yamaha GP760 can reach the amazing 52-54 mph even with the smaller engine option!
The upgraded version of the 760, the GP800 hit the market in 1998.
It got a slightly bigger, 784 cc, 2-cylinder engine. With this power source the performance of the Yamaha GP800 jumped up to 120HP, as its top speed also reached the 55mph.
In 2002, the GP800 got a completely new design, and was re-indroduced as the GP800R. It had the same hull as the GP1200R, which was around 3 inches longer and an inch wider. This new shape eventually led to a 93-pound weight gain, while it’s engine remained unchanged.
This means that the GP800R offered 120HP and a top speed of around 55mph, just like its predecessor.
Sadly, the greater weight and the same performance resulted in a worse power-to-weight ratio. (GP800:0.24, GP800R: 0.20 HP/pound)

If you stick to these 2-stroke PWCs, this means you are selecting from very aged models.
If you are looking for a Yamaha GP760 or GP800 to buy, you may want to know where you can still purcase one.
It would be best if you start your research in the fan groups on forums and social sites. You can find a lot of useful info on these models, and sometimes some good deals!
But if you don’t, you can still find many Yamaha GP800s for sale on Craigslist, PWCTrader, and other online ad sites.
Prices? They may surprise you!
Yamaha GP760 and GP800 Prices
The Yamaha GP760 prices start from $1,000 and go up to $2,500. In contrast, GP800 prices range from $2,000-$3,500, while a GP800R costs around $2,500-$4,000. The price strongly depends on their condition. If you find some at a much lower price, always be suspicious. If the craft is not water-ready, and the ad says that „it needs work,” it’s best if you walk away.
As you can see, these Yamaha GPs still have asking prices that are quite high. It seems they are like fine wines!
As 2-stroke sit-down WaveRunners have not been in production for a long time, there are fewer and fewer of them for sale. Moreover, many of these crafts are heavily modified to reduce porpoising or for better performance. And these mods all affect the asking price!
Another factor to consider is that many of these mods increase the PWC’s fuel consumption as well.
Conclusion – Are Yamaha GP760 / GP800 Still Worth Buying?
Are GP760 and GP800 WaveRunners still worth buying? This is a typical question of many buyers, and the answer is that it depends.
If you are considering buying one of these PWCs, here are some factors to consider:
Capacities: As we discussed above, these crafts are mainly ideal for solo rides. This is because their small, flat hull becomes tipsy when it has a bigger load. They also have smaller storage and fuel capactities compared to a newer 4-stroke WaveRunner.
Porposing: Don’t forget that all of these old GP WaveRunners are prone to porpoising. Although you can reduce this effect by installing aftermarket parts like trim tabs, ride plate and so on, they are not able to eliminate the issue completely.
Reliability and durability: Keep in mind that these old 2-stroke PWCs typically require more attention compared to the 4-strokes. If you don’t have mechanical skills, you may run into difficulties if you have to adjust the carburetor or fix other parts. Beware that these issues can happen more often than you think. Additionally, their engines are worn out, and if you have to repair or even rebuild them, it could be a big hassle.
Costs: Regarding costs, they are cheaper to buy, but more expensive to operate due to the repair costs and their high fuel consumption. You can also expect lower fuel mileage and if you ride hard you can even dry a GP’s fuel tank in an hour!
If you are still stuck on the vintage GPs, you must be wondering which one to choose.
When it comes to the Yamaha GP760 vs. GP800 vs. GP800R debate, we can say that the GP800R is the best pick. This is becasue this model is less prone to porpoising due to their new hull design.
It also features a bigger, 15.9-gallon fuel tank, which is 2.5 gallons more compared to its predecessors.
If you are looking for more power, the GP1200R could be a better deal. It offers a higher performance (155HP) thanks to its bigger 3-cylinder engine. However, it has much higher fuel consumption as well.
Before you make you purchase, never skip the water test and make sure you check the compression in the cylinders.
As a final word, our recommendation is that if you are a beginner, purchase a newer, 4-stroke, Rec-Lite or Recreation PWC. If you want to ride your craft more often than you work on it, these old 2-stroke WaveRunners are probably not for you.
But if you have mechanical skills and you like working on engines, fixing these vintage crafts can be part of the fun.
In the end, it’s up to you!
