Characteristics of Jet Drives

A closer look at Yamaha's internal jet drive propulsion system.

Brief Summary

The SX210 is Yamaha’s entry-level sportboat. It brings a large amount of family fun to the party for relatively short money.

Heading out on the water in a small boat is the staple of shore-side Americana. And in tough times like today, small boats are the workhorses of family good times, more than ever before. Yamaha has a line of sport boats that not only pack a lot of fun in a small space, but they do it for less money than much of the competition. That feature alone is typically the tipping point for most buyers, but when you add the safety factor of not having a spinning propeller under the swim platform, and two engines for the price of one, then the jet boats have a pretty strong sales proposition.

    All fuel consumption numbers are the total for all engines in the boat. Speeds are measured with Stalker ProSports radar gun or GPS. Fuel consumption (gallons per hour) measured with Floscan digital fuel-flow meter or by on-board factory-installed diagnostic instruments. Range is based on 90% of published fuel capacity. Sound levels determined using Radio Shack digital decibel meter on A scale. 68 dBA is the level of normal conversation. Time to plane is measured from start of acceleration to formation of rooster tail behind boat.

    Captain's Report

    Captain Steve Says...

    Yamaha SX210 2011
    Yamaha was the first builder to make the stern platform a third venue on sportboats.

    The SX210 is Yamaha’s entry level sportboat. It brings a large amount of family fun to the party for relatively short money.

    Prepare for Boarding...

    The layout of the SX210 interior is not too startling as far as sport boats go. The bow is very roomy thanks to the deckboat style bow that has the forward seats spread apart enough to prevent knocking knees. There’s storage under the seats and drink holders in all the right places. If you’re a fan of beach boarding, the three-step bow ladder will be a big hit. The helm features a swivel bucket seat, full instrumentation and rocker switches with circuit breakers right next to each one. Yamaha mounted the engine controls on the horizontal, which makes them much easier to use. They mount them at an angle on some of their other boats and I’m glad to see the evolution here.

    Yamaha SX210 2011The rest of the cockpit space is taken up with seating that wraps all the way around. Surprisingly absent is the port side seat with the flip back. It’s all lounge seating here, so the cockpit table is almost required for most days on the water. The upshot of having this much seating is… underneath it all is gobs of storage, in addition to a deck cooler and additional deck storage forward. This will not hold your skis and wakeboards, but this isn’t a problem here, because in the port side compartment (where you might think a head goes) is storage that runs forward under the port side bow seats. It’s more than sufficient to hold all the long toys.

    The Transom...

    Everyone tries to imitate the Yamaha transom but it is difficult because of the extremely low profile of the Yamaha engines vs. the Vortec automotive blocks used by most stern drive engine makers. Yamaha’s low profile jet drive engines eliminate the engine box. Yamaha exploits this to its best advantage and creates a stern area that has become not only the focal point of this boat, but the whole new generation of sportboats. It’s a very comfortable location for hanging out or swimming and with the table installed, it becomes a fun and unusual venue for cocktails or hors d’oeuvres. In the upper level of the two tiered platform is a hatch which leads to the jet intakes. If there’s a clog, (usually sea grass of some sort) this is where it will be, and you can simply reach in and unclog (usually sea grass or some sort) )it without having to get in the water. This is a feature lacking in some of the other jet boats we’ve seen.

    Engines and Construction

    The SX210 is powered by two high-performance, four-cylinder, 1052cc Yamaha marine engines. Electronic fuel injection feeds each of these powerplants, providing hard-to-beat times-to-plane. The engines are connected directly to twin 155-mm hyper-flow jet pumps with three-bladed stainless steel impellers.The bottom is a modified deep-V with a 20-degree deadrise at the transom. The hull and deck are cored fiberglass. Fiberglass stringers are fabricated separately, then laminated into the hull and injected with foam to provide extra floatation. The fiberglass liner is bonded to the hull and stringers with polyurethane adhesive and then injected with foam to provide floatation as well as longitudinal and lateral structural rigidity. The deck molding is fastened to the hull with both mechanical fasteners and polyurethane adhesive giving this semi-monocoque fiberglass structure substantial strength and rigidity.All of these construction procedures are pretty much standard among builders of higher-priced boats. It is important to note that while the SX210 is relatively low-priced its construction regimen takes a back seat to no one.

    Specifications...

    The Yamaha SX210 has a LOA of 21’ (6.4 m), a beam of 8’6” (2.6 m), and a draft of only 16” (.4 m). She has a dry weight of 2,802 lb (1,270 kg) and she holds 50.2 gal (190 L) of fuel. Yamaha calls this their entry level watersports boat, but they obviously didn’t get the memo on what entry level means. This boat comes complete with the tower and trailer for just under $33,000. Take that number and compare it with any other boat on your short list, and the list will get noticeably shorter in a hurry.

    Recommendation

    Not only is the Yamaha SX210 a well-built boat, but since Yamaha builds everything in-house, there’s no finger-pointing between the engine maker and the boat builder if there is an engine or jet pump warranty claim. It’s all Yamaha, so that gives you peace of mind when you walk out the door. Add the safety margin of jet drives and you’ve got yourself one heck of an entry level package.

    Yamaha SX210 2011The one unusual aspect of this boat is its “U”-shaped seating in the cockpit and the absence of a swivel companion seat on the port side opposite the helm. Also there is no head compartment in this model as there is in larger-sized Yamaha boats. We suggest that buyers look at all the Yamaha models and take a test ride to determine which model is best for them.
