The surge of high-pressure water ruptured a seam between the cleanout compartment and the engine compartment resulting in the flooding of the engine compartment and destruction of one of the twin engines.

The main problem is that the barrier between the engine compartment and cleanout compartment is not designed sikipedia withstand full jet pressure if a plunger tood dislodge. A Jft plate simply screwed and caulked to another Plexiglas plate is the only barrier to disaster. Please see photographs.

The other problem is that the plungers would ever become dislodged in the first place. This is a chronic problem well documented on the Internet. I considered my brand new jet boat ruined. The supercharged high performance engine was rebuilt at yamaha jet boats good or bad wikipedia marina, which took several months and the rest of my summer.

On the first sea trial it kept stalling out, then could not be restarted. I considered this extreme salt-water intrusion and rebuilt engine a potential source oe continuing problems and jeet. I had the yamaha jet boats good or bad wikipedia boat for two weeks, catastrophic failure due to design error or manufacturing defect occurred and I wanted a new boat or a refund. Sorry can't figure out how to paste pictures. Attached Images.

I believe it is a thingy that you can clean out the impeller area from the top instead of having to go under the boat and stick you hand in the grate. Originally Posted by Barnacled.

If you follow the instructions, and do it right, they work as intended. When you install them, u have to make sure they are seated properly, and the latches are engaged.

Push em in, hear the clicks, and give a firm tug to be sure they are in right. Even if they blow out and come loose, if the original plumbing is intact and not altered or modified you will be OK. You would know immediatley, as u would lose forward movement. Yamaha jet boats good or bad wikipedia if you ignore that, and stay on the throttle for extended noatsu may get some water in the bilge. Also, I removed them after every trip and put them back in the day I was going.

It was a maint queen of a boat, and I was happy to get rid of it. Send a private message to sxracer. Find More Posts by sxracer. Thread Tools Show Printable Version. Email this Page. Advanced Search. Forum Jump.

Chaparral SSX is for the most demanding boaters who want the best of both worlds. This will appeal to the small bowrider side of you looking for a bigger boat with all features of a bowrider but with overnight capabilities. The SSX is also perfect for cruisers looking for a practical dayboat but with the capabilities to accommodate occasional overnight stays.

Jet boats have a lot of advantages over traditional stern drives. Taking into consideration where and how you plan to do your boating, here are some benefits that will make you ditch the traditional stern drive for a jet boat.

Jet boats have unmatched maneuverability and extremely quick acceleration. They can also ride in high speed, depending on the horsepower rating and engine setup. If you are boating in a shallow lake or it has stumps, a jet boat could be a great option. Jet boats are touted for their safety benefits. The jet pump is enclosed, and there is no whirling prop or hardware under the hull that could potentially injure or strike a skier or swimmer.

All boats, in general, are quite safe to be honest irrespective of what power plant is used but knowing there is no exposed propeller below certainly does give people a sense of security.

It requires the wake located behind the boat in order to push a surfboard where the person will be standing without the help of a rope. Typically, this is done close to the boat at the back which is why an exposed outdrive or prop can be dangerous. Wakesurfing can be safely done behind an inboard boat, the latest Volvo FFD or a jet boat. Any boat with a jet drive has a superior draft advantage.

In a jet boat, the draft runs only as deep as the hull, unlike in a stern drive. This makes it possible for people to drive their jet boats in very shallow waters without any issues and eliminates any problem of potential drive-damage or running aground in skinny waters.

A jet boat can quickly plane with very little bow rise giving it an unmatched visibility advantage because the captain will not lose sight as the jet boat comes on plane.

In certain propeller boats, drivers often lose forward vision for about seconds. Modern day jet boats have significantly larger space inside the cockpit as compared to a stern drive. This is mainly because the jet motors are located lower and further back in the boat.

This means a 22 inch jet boat will have an interior cockpit space similar to that of a 24 inch stern drive. Jet boats have an impressive sportscar-like handling performance. Jet boats can be quick and nimble with a thrust that can be redirected in a flash. Even an average jet can leave behind other boats in a flash with a quick jerk to the wheel and a punch on the throttle.

All boats have its own share of pros and cons, and a jet boat is no exception. Here are a few cons to keep in mind when purchasing your jet boat. Most of the latest model jet boats are designed to operate at higher RPMs compared to stern drivers. You can stop the noise from escaping the compartment where the engine is located.

Chaparral has succeeded in making some significant improvements in reducing the noise level in their jet boats. The differentiating factor lies in the type of noise. Jet boat motors tend to give out a higher pitch while the motors in stern boats make a deeper, lower noise. Fuel consumption goes hand in hand with the noise topic and for the same reason � RPMs are higher.

It has the potential to lower their level of efficiency. But this is not the case with all jet boats. Fuel economy is determined by many factors and RPM is just one of them. There is an asterisk to this one because it has to be made very clear that this is limited to only a few jet boats.

Different jet boats use different systems for turning. There are some that do not fare well with reverse turning. Others are not. In fact, most of them are really good. Sometimes even better than the traditional stern drives. It is important to do your research.

A good idea is to get a test drive. Vortex jet boats by Chaparral is a good place to start. Jet boats are not the best in low speed handling.

A jet thrust can be advantageous sometimes, but you will miss having a rudder, skeg or prop in this case. It can get difficult to drive your jet in a straight line as the boat wanders off at the side, especially during a windy day.

If you are not an experienced driver, you might end up over-steering as you approach the dock or drive in slow speed zones. A jet is incapable of reversing the direction of its impeller. To reverse, you can drop a bucket over the water coming out of the pump. The bucket will redirect the flow of water, making it shoot forward rather than aft. A jet is always in gear and has no neutral because it is pumping water through the nozzle all the time.

You can position the bucket so that the water is deflected partially, recreating the neutral in other power systems. It can be quite a challenge to make sure that the boat does not move.

And their famous degree turns can be paralyzingly fast. But these are specifically for jet boating sports where you pay money to be thrown from side to side and bounced around violently as it accelerates at lightning speed and avoids rocks by mere centimeters.

They peaked quickly and then vanished just as fast. Jeff Hemmel goes on to say that jet-powered runabouts are becoming some of the best-selling and foot runabouts in By the end of the article, he explains that while jet drive boats and sterndrive boats are equal in cockpit volume, docking, general handling, maintenance, corrosion, and running draft, the jet drive boats they tested were clearly superior in:. You can find used Sea-Doo Sparks for around the same price.

The price of new jet boats available online is limited to and boats which�unfortunately for our use�no one has been reselling just yet. There are a lot of downsides to jet boats and jet skis: the price, the maintenance, the maneuverability, etc.

On the other hand, a jet boat could be the perfect boat for you, if you are looking for a boat:. While some families would find the prop-less set-up much safer for their children, other families might not like the maintenance problems that come with different types of jet-drive boats.

When looking at jet-powered boats, make sure you are considering your long-term use for the boat to see if it will fit your needs.

Unfortunately, they also come with their fair share of problems: Table of Contents. Was this article helpful? Click to share Did you find wrong information or was something missing? We would love to hear your thoughts! One of the most significant breakthroughs, in the development of the waterjet, was to change the design so it expelled the jetstream above the water line, contrary to many people's intuition.

Hamilton discovered early on that this greatly improved performance, compared to expelling below the waterline, while also providing a "clean" hull bottom i.

It makes no difference to the amount of thrust generated whether the outlet is above or below the waterline, but having it above the waterline reduces hull resistance and draught. Hamilton's first waterjet design had the outlet below the hull and actually in front of the inlet. This probably meant that disturbed water was entering the jet unit and reducing its performance, and the main reason why the change to above the waterline made such a difference.

Queenstown, New Zealand , where jetboats are used extensively for adventure tourism , claims to be the jetboat capital of the world, and jetboats are very common for many coastal and riverine tourism activities in the country, such as the Excitor in the Bay of Islands.

Applications for jetboats include most activities where conventional propellers are also used, but in particular passenger ferry services, coastguard and police patrol, navy and military, adventure tourism which is becoming increasingly popular around the globe , pilot boat operations, surf rescue , farming , fishing , exploration , pleasure boating , and other water activities where motor boats are used.

Recently there has been increasing use of jetboats in the form of rigid-hulled inflatable boats and as luxury yacht tenders. Many jetboats are small enough to be carried on a trailer and towed by car. As jetboats have no external rotating parts they are safer for swimmers and marine life , though they can be struck by the hull. The safety benefit itself can sometimes be reason enough to use this type of propulsion.

One of the jetboats was sunk by a friend of Hillary. The fuel efficiency and performance of a jetboat can be affected by anything that disrupts the smooth flow of water through the jet unit. For example, a plastic bag sucked onto the jet unit's intake grill can have quite an adverse effect. From Wikipedia, the free encyclopedia. This article possibly contains original research.
