Yamaha SuperJet 701 RN Review
The Yamaha SuperJet Series
Before the appearance of the SuperJet, Kawasaki Jet Skis dominated the stand-up PWC market.
But everything changed in 1990 when Yamaha introduced its first stand-up PWC, the Superjet 650. This model was phased out in 1994 by the single-carbed SuperJet 701.
Thanks to their lively engine and excellent design, these skis become widely popular among racers and recreational riders.
Due to their square bow design, these skis were often referred to as the “square-nose” SuperJets.
The second generation “round-nose” SuperJet platform was introduced on the 1996 SuperJet 701, which housed the more powerful twin-carbed 701 engine.
This model was upgraded again in 2008 and remained in production through 2020.
In 2021, the 2-stroke SuperJet was phased out by its more advanced 4-stroke successor.
In summary, the list of production SuperJets completed with the FX-1 stand-up is as follows:
- 1990-1993 SuperJet 650
- 1994-1995 FX-1
- 1994-1995 SuperJet 701 (“Square Nose”)
- 1996-2007 SuperJet 701 (“Round Nose”) – GEN1
- 2008-2020 SuperJet 701 (“Round Nose”) – GEN2
- 2021-today 4-Stroke SuperJet

Yamaha SuperJet 701 RN Hull and Top Deck
The 1996-2007 Yamaha SuperJet was often referred to as the round-nose SuperJet 701, or just SuperJet 701 RN.
This was no coincidence since this model came built on the second-generation SuperJet platform.
Unlike its predecessor, which featured a squared bow design, the new platform was engineered with a sleeker, more rounded top deck. Hence the name “Round Nose” (or RN).
Unlike its top deck, the hull of the ski remained completely unchanged.
Therefore, just like its predecessor, the 701 RN measured 88.2 inches in length, 26.8 inches in width, and 26.0 inches in height. Its dry weight also remained at 291 pounds.
The 701 twin engine of the SuperJet was also upgraded for the 2006 season.
Let’s drill into the details and take a closer look at this powerhouse!
Yamaha SuperJet 701 RN Engine
The round nose SuperJet 701 was powered by a twin-carb version of the 2-stroke, 701cc, twin-cylinder Yamaha marine engine.
While its simpler sibling featured a single Mikuni BN44 carburetor and delivered 62.5hp, the new variant enjoyed two Mikuni BN38 carbs, which ensured an engine power of 73hp.
Besides its twin-carb configuration, the new 701 engine came standard with many advanced technologies, including:
- CDI ignition
- Reed valve intake system
- Electric start
- Twin Mikuni BN38 carbs
- Open-loop cooling system
- NGK BR8HS spark plugs
The propulsion system of the SuperJet 701 RN was an axial-flow, single-stage jet pump that lacked trim and reverse systems.
Yamaha SuperJet 701 RN Performance
While its single-carbed variant topped out at 43.5 mph, the twin-carbed SuperJet 701 RN could reach 45.4 mph out of the box. With some aftermarket mods, this could be increased into the ballpark of 50-60 mph!
The claimed fuel consumption of the ski was 7.7 gph at full speed, so its 4.8-gallon fuel tank ensured a limited playtime of 36 minutes.
The well-designed hull of the SuperJet 701 made it capable of various tricks, making this model the choice for many freestyle racers.
It’s safe to say that this model become more popular than any other competitor ski from Kawasaki!
Yamaha SuperJet 701 RN Features
The features of the 1996-2007 SuperJet were carried over from its square-nose predecessor, including:
- 4.8-gallon fuel tank
- Riding tray with deck mats
- Steering pole cover
- Fire extinguisher container
- Bow and stern rope holes
- Storage pouch

Yamaha SuperJet 701 Problems
Even though Yamaha PWCs were known for their reliability, the SuperJet 701 had some common problems, including:
- Pump durability: If the ski was used in salt water, its pump was prone to wearing out very quickly.
- Ignition issues: Its CDI box was prone to leaking, which often caused ignition problems.
- Defective start/stop switch: The start/stop switch on this ski often failed, causing many headaches for owners.
- Defective steering cable: The steering cable also proved to be weak and had to be replaced occasionally.
- Lack of an oil injection system: Last but not least, don’t forget that the SuperJet was designed without an oil injection system. This meant that riders had to pre-mix the fuel in cans before each ride.
