Yamaha Ls2000: A Worthy Boat Investment?

The Yamaha LS2000 is a jet boat that was introduced in 1999 as the successor to the Exciter series. It features a twin-engine package, with each of the two engines producing 135hp for a combined 270hp. The boat measures 19 feet 6 inches in length and 8 feet in width, with a shallow hull design that makes it very maneuverable but rough on the chop. Its dry weight is 2100 pounds, and it has a large 41-gallon fuel tank and a 7-person capacity, though it is most comfortable for 5. The LS2000 has a top speed of 53-54 mph and is known for its fast acceleration and instant throttle response, making it a great tow boat. However, common problems include the need for frequent maintenance due to its 2-stroke engine design, issues with oil lines, loud engine noise, and poor rough water performance. Overall, the LS2000 is a good choice for those looking for a fast, agile, and powerful jet boat, but it may require more maintenance than some of its 4-stroke successors.

Yamaha LS2000's engine and maintenance

The Yamaha LS2000 is a dual-engine boat with carbureted 2-stroke engines. While the boat is generally reliable, there are some maintenance and reliability issues to be aware of.

One key issue is the oil lines, which have been known to fall off, leading to engine failure. As such, it is recommended to upgrade the oil lines or convert to pre-mixed fuel. Another issue is that the LS2000 can be smoky, particularly at idle. This may be dependent on the oil used.

When flushing the cooling system, it is important to ensure that the engine is running before turning on the water, and to turn off the water before turning off the engine. This is to prevent water from flowing into the engine cylinders and causing damage. Additionally, when cranking the engines with the spark plugs removed, the wrist lanyard should be removed to disable the ignition system, as failing to do so can damage the ignition box.

In terms of storage, it is not recommended to store the LS2000 in the water for long periods, as debris can collect in the jet pumps and salt water can cause corrosion. It is also important to ensure that the drain plug is removed when storing the boat, to prevent rainwater from collecting inside the hull.

Other issues that have been noted by owners include a lack of a windshield, making it less comfortable in cool weather, and challenges with low-speed steering and using the clean-out ports. The LS2000 also has high fuel consumption, particularly when run hard, and can be loud, with limited RPM range.

However, the LS2000 has been praised for its speed, size, ease of navigation and docking, and positive comments on its appearance. It is also relatively easy to tow due to its light weight. Overall, the LS2000 can be a good first boat, especially if one can perform maintenance themselves, but it is important to be aware of its quirks and limitations.

LS2000's performance and handling

The LS2000 is a fast and nimble jet boat, with a top speed of 53-54 mph. Its shallow-V hull design makes it agile and manoeuvrable, but this also means it's rough on choppy water. It's not recommended for large lakes or the ocean.

The LS2000 is powered by two 2-stroke, 1131cc, triple-cylinder, reed-valve Yamaha marine engines, which produce a combined 270hp. The engines are carbureted and fed by three 44mm Mikuni carburetors. The boat is easy to manoeuvre with its twin throttle lever, and its jet propulsion system makes it a great tow boat for water sports.

The LS2000 is rated for seven people but is really only comfortable for five. It has a relatively small amount of storage space for a boat of its size, with compartments including an under-floor ski locker, an under-seat storage area in the bow, a glovebox, a storage tray above the engine bay, and two smaller storage units under the windshields.

The LS2000 is a good first boat, but it requires more maintenance than its 4-stroke successors. The oil lines are prone to cracking or falling off, so they need to be inspected and replaced periodically. The engines are also quite loud, and the boat is very fuel-inefficient.

LS2000's price and value for money

The Yamaha LS2000 is a great first boat, especially for those with previous experience with jet skis, as the maintenance and reliability are similar. The LS2000 is a good option for those looking for a fun, fast, and nimble boat for cruising and water sports. It is easy to navigate and dock, and can comfortably fit 5 people (7 if not doing any water sports).

The LS2000 is a good value option for those looking for their first boat, as it is significantly cheaper than newer models, with prices ranging from $7,000 to $14,500. However, keep in mind that this is an older model with a two-stroke engine, so it will require more maintenance and burn more fuel.

When considering the purchase of an LS2000, it is important to inspect the boat thoroughly. Some common issues to look out for include oil lines that may need to be replaced or clamped, and fuel filters that may need to be cleaned or replaced. Additionally, it is recommended to upgrade to pre-mixed fuel to avoid issues with the oil lines falling off.

Overall, the LS2000 is a good value option for a first boat, offering a fun and fast experience on the water, but it is important to be aware of the maintenance requirements and fuel consumption associated with this older model.

LS2000's safety features

The LS2000 is a jet boat manufactured by Yamaha. It is a good first boat, especially for those with previous personal watercraft experience. It is a reliable, easy-to-maintain, and fun boat. However, there are some safety considerations to keep in mind when operating an LS2000. Here are some key safety features and procedures to follow:

• Oil Lines: The original oil lines are known to fall off, resulting in potential engine failure. It is crucial to upgrade or regularly check and maintain the oil lines to prevent this issue.
• Flush Hose: When flushing the cooling system, always start the engine before turning on the water and ensure the engine is running when shutting off the water. Running water without the engine running can cause water to flow backward into the engine cylinders, leading to significant damage.
• Lanyard: When cranking the engines with the spark plugs removed, remove the wrist lanyard to disable the ignition system. Failing to do so may result in damage to the ignition box.
• Storage: Avoid storing the boat in the water for extended periods. Debris can accumulate in the jet pumps, causing starting issues, and salt water can lead to severe corrosion. If you must store it in the water, install a backup bilge pump with a float switch and a backup power source.
• Drain Plug: Do not store the boat with the drain plug inserted. Rainwater can collect inside the hull and cause flooding in the engine compartment.
• Cleanout Plugs: Ensure the cleanout plugs are secure and tied together with a rope to prevent loss.
• Fuel and Oil: Use regular unleaded gasoline and TC-W3 certified outboard oil.
• Passenger Capacity: The LS2000 has a maximum capacity of seven people. However, for comfort and to avoid overloading the boat, it is recommended to limit the number of passengers, especially when engaging in water sports.
• Smoke: The LS2000, being a two-stroke engine, may produce smoke, especially at idle. This can be minimised by using the appropriate oil.
• Maintenance: Stay on top of regular maintenance and winterisation to ensure the boat's reliability and longevity.

LS2000's size and capacity

The Yamaha LS2000 is a jet boat measuring 19 feet 6 inches in length and 8 feet in width, with a draft of 18 inches. Its dry weight is 2100 pounds and it has a fuel capacity of 41 gallons, with a 7-gallon reserve and a 2.6-gallon oil tank. The LS2000 is rated for 7 people but is actually only comfortable for 5. It features a three-person bench seat in the aft section and two bucket seats in its bowrider-style front design. It has a shallow hull design, making it very manoeuvrable but rough on the chop.
