3 Common Yamaha Sx210 Problems Along With Solutions

Owning a Yamaha Sx210 can be quite thrilling for traveling through the water. But it also comes with some problems along with the fun experience. Having a clear idea about these issues will give you an upper hand in handling this boat.  

That’s why we’ve mentioned some of the common problems faced by Yamaha Sx210 and their respective solutions. Let’s see if getting this boat is worth these problems-

Problem 1: Too Loud When Crossing 40 MPH Threshold

The Yamaha sx210 has a peak speed of 51 miles per hour. However, it has a top speed of 65 mph. These jet boats typically go at a speed of 25 miles per hour. If the water jets are more efficient, which is around 60 mph, these can go much further. 

When you’re out on the water in most boats, you don’t need to wear ear protection. Regrettably, this is not always the case with Jet boats. They double in decibels as soon as they pass the 40 mph mark.

And if you continue to run the jet boat at this speed for a while, it’d cause more issues. Your boat engine might get damaged. Besides, your boat might flip over due to the shaking of the boat engine.


The only solution for this is to maintain a balanced speed. Because exceeding the 40 mph mark arises the issue. 

Problem 2: Sucking Up Objects In Shallow Water

Jet skis have a habit of sucking up foreign things when in shallow water. Sand, algae, rocks, seaweed, and other foreign items are frequently absorbed by it. As a result, the impeller may be damaged. 

Furthermore, depending on the object, it might damage in numerous forms. And continuing to run the boat without fixing the issue might stop the outboard engine eventually.


The solution is to turn off your engine before approaching shallow water. Then let the river and momentum carry you to the shore. Allow a companion to push you off as you take off. Before you start your engine, the water should ideally wash away the sand.

Once you see the sand is removed, you may get started again. But if you still notice plenty of sand particles, don’t take a risk. 

Make sure to clean it properly. You may take the help of chemical cleaning agents for this as well.

Not sure what type of cleaner to use for this? Well, no worries! Because we’ve got you a couple of suggestions here-

These are the cleaning agents that can be used for multiple purposes. These products are quite effective in getting rid of soft and hard dirt particles.

Problem 3: Poor Fuel Consumption

Modern jet boat engines have higher RPMs. Yamaha Sx210 is no exception in this case. The higher RPM reduces their fuel efficiency. And this leads to the Yamaha boat Fuel problems that are common nowadays. But don’t get things twisted. Because every engine and boat is a little bit different. 

So, they aren’t all bad when it comes to fuel consumption. 

However, they have a reputation for being one of the least fuel-efficient types of boat. Remember that fuel efficiency is determined by a variety of factors other than RPMs.


This problem does not have an ideal solution to be exact. You may still maintain a couple of things to maintain the rhythm of your jet boat. 

First of all, consider not to exceed 40 mph. At least make sure you don’t do it often. Because exceeding this or often running the boat at a very high speed can be harmful. Maintain proper servicing of your boat. And don’t forget to lube the steering cable on a regular basis. 

Henceforth, your boat’s performance would be as expected. 

So, these were common Yamaha sx210 problems you might face.
