Captain's Report by Capt. John--
Start with the Facts
The SX192 weighs in with a dry weight of 2,150 lbs. which is important to note since she is one of the lightest boats in class, and lighter than some 18' models. Leaning on its experience in PWC design and its larger twin engine jet boat designs, the 192’s hull is a marriage of all that the team at Yamaha has learned over the years. Not only does Yamaha manufacture and assemble the entire hull and deck components, they also design and build their own engines. In our opinion, this is a huge advantage from a service, reliability, and warranty point of view. It sets Yamaha apart from their competitors. The power comes from the 1.8L, four-cylinder, four-stroke, 16 valve supercharged purpose-build Yamaha Marine engine. The 16 valves provide greater efficiency in how the engine breaths while the supercharger boosts horse power by forcing more air into the engine.
At the transom the deadrise is 18 degrees and because this is a jet drive power system, the draft is only 14”. This shallow draft is due to the fact that there is no lower unit or an outboard prop down below the bottom of the hull. This provides for excellent skinny water access. Her beam is a 8' (2.43 m) and she carries 30 gallons (114 L) of fuel. Even though this is a high performance engine, it has been optimized to run on regular 87 octane unleaded fuel. The jet drive unit consists of a three blade stainless impeller with a 14.3-degree pitch.
Starting forward, Yamaha knows how much fun it is to anchor off a beach or in a quiet cove. With this in mind, the 192 has a molded-in, self-draining anchor locker with room for line.
When looking at a side view of the SX192 it is obvious that the interior width is pushed as far forward as possible, creating a distinct push out or flared look where the hull and deck meet. This was necessary to provide enough room for adults up at the bow. There is storage under the bow seating with the port side opening up into the console behind design for your large and longer items.
At the helm is the cruise assist which allows the throttle to be set and then increased or decreased by clicking up or down on the rocker button. There is also a three position no-wake mode, actuated via a rocker switch so idling in and out of the marinas takes just the push of a button. The “U” shape seating wraps around the aft cockpit. It features the plush, high-quality upholstery that is standard on Yamaha’s entire lineup.
To port in the console is storage bin which also has a 12v outlet, the MP3 jack and stereo. This is held open by a spring support. A gutter runs around the edge, to help keep things dry inside.
The next area is one that we have been showing on Yamaha boats for years: the stern seating and swim area. Since the engine is so compact, it allows the designers to provide boaters more usable space at the stern.
The stern seating has comfortable back rests with cup holders to either side and a ski point on centerline. The cleanout port for the jet drive unit is under the seat. The swim ladder is located under the swim platform and the addition of two grab handles will make reboarding easier. The waterjet propulsion requires no exposed propeller, which has obvious advantages for a family with small or younger kids.
This nineteen-footer, from the tip of her roomy bow seating area to the output of her 1.8 liter supercharged engine, is one little fun machine. Heading off the dock, she was responsive. I never felt like I had to react to the maneuvering peculiarities of a jet drive as I’ve had to do in the past with earlier models. Sure, she’s a nineteen-footer at an attractive price, so I didn’t expect to be riding in the lap of luxury. But Yamaha’s automated production efficiency and attention to detail has provided a feel of luxury I don’t normally expect to find at the entry level in a boat that is all about water sports. Our test boat tipped the scale at 2660 pounds, including two of us on board. As we accelerated, the GPS struggled to keep up with us as we were on plane in 3.5 seconds and the needle hit 30 in 5.1 seconds. The hull seems to be a perfect match for Yamaha’s purpose-built engine, and I understand that the hull shape is the result of a bunch of tweaking to get the shape of the entry just right. It felt good to me. Our best cruising performance was observed at 5500 rpm where we saw a speed of 25.55 mph using fuel at a rate of 8.3 gph for a range of 83 statute miles, and our top speed was 50.6 MPH at 7700 rpm, wide open throttle. An improvement I look forward to seeing from Yamaha is full fly-by-wire throttle control. Right now, the throttle lever is linked to the electronic controller by aviation-type wire linkage. Since they already have the electronics in place, it makes sense to me that they should make this change one of these days. On the other hand, one improvement they have made is very effective indeed; it’s called “Thrust Directional Enhancer” and it serves to improve slow-speed handling. It sounded like a sales pitch to me, but I’m pleased to say that my skepticism was proven wrong. This is the most maneuverable jet drive boat that I have ever brought in to a dock. I’m sure a beginner could feel confident right out of the blocks. Between her ease of maintenance, standard features, and attractive price, it’s not a wonder that Yamaha seems to get more popular with boating families every year. We think this new model offers all the standard features one would expect in a larger boat, but with the twist of industry-leading engine technology. This boat comes with a painted trailer as a complete package starting at $30,999.
