2005 Miami International Boat Show - Outboard Engine Highlights
A look at the latest outboard engine technology
Article and photos by Greg Terzian

A view from inside the convention center at Miami.  The Miami International Boat Show is one of the largest in the world.

One of the world’s largest boat shows, the Miami International Boat Show covers everything from mild to wild, from six-foot long car toppers to seven million dollar yachts and everything in between. This year’s show boasted an attendance of over 2200 exhibitors and more than 3000 watercraft on display.  The show is divided into two segments – the exhibitors and boats on display in and outside of the Miami Convention Center and the in-water component of the show, located at the Sealine Marina at Miami Beach. Our coverage is once again primarily focused on performance boating and the outboard engine manufacturers that power those performance boats.

Last year Mercury Marine made headlines around the world with the introduction of their all-new, six cylinder four-stroke supercharged outboard called the Verado. The unveiling of this revolutionary engine sent marketing personnel and engineers from other outboard manufacturers scrambling to salvage what little spotlight there was left for them in the shadow of Mercury’s Verado. But that was not all, as the introduction of the double-supercharged 1075 SCi racing sterndrive system redefined power and good manners into a package that was a sight to behold. Clearly, Mercury Marine stole the 2004 show at Miami, but what happened this year?

For 2005, Evinrude's display of E-Tec outboards was impressive.

Once again, Mercury Marine stole the spotlight, with the unveiling of the four-cylinder, supercharged Verado engines. The new engines are available in 135, 150, and 175 horsepower varieties, all based on the same four cylinder, in-line engine. What’s most impressive is the weight class these engines fall into – that of larger 2-stroke V6 engines. Four-stroke engines are getting lighter, while taking advantage of remarkable technologies that have thrived in the automotive market.

Triple Mercury OptiMax 250XS engines power this Spectre 32 tunnel boat.  The 2-stroke OptiMax is an emissions-friendly 2-stroke with blistering performance.

Mercury Racing did not disappoint either, with the introduction of the new 600 SCi  and 850 SCi stern drive systems, as well as the new SystemView Race Edition, which can display vital information on four engines at the same time. Improvements to Mercury’s SmartCraft system have also been added, including the new “Shadow Mode”, which allows system software to control the center engine in a three-engine installation. This frees the operator to concentrate on two throttles and shifters, rather than three.

Not all surprises were in the form of large-displacement engines. New four-stroke engines added to Mercury’s stable include the new 25 and 30 horsepower electronically fuel injected engines. These new engines can be rope-started with no battery to support the onboard fuel injection components. The last bastion of survival for the old carburetor is now seeing its end.

Engine introductions aside, Mercury also had an impressive lineup of boats in the water for us to experience first hand. Among the many performance crafts was a new 32-foot Spectre tunnel boat, powered by three OptiMax 250XS outboards. Driver Mike Seebold was not afraid to take the new tunnel boat over 100 MPH while I struggled to keep my camera steady. It was an exhilarating ride that left a very positive impression Mercury’s OptiMax platform.

Evinrude introduces the new E-Tec V4 115-horsepower engine to members of the press.

While there were rumors of a comeback from other outboard manufacturers, Yamaha, Honda, and Suzuki’s exhibitor’s booths remained curiously quiet – in most cases, simply displaying the same products as last year. But Bombardier Recreational Products (BRP) fulfilled the promise of a comeback from 2004’s underwhelming display with their impressive line of two-stroke E-Tec outboards, unveiling a new Evinrude 115-horsepower, V4 engine. In 2004, BRP had many of its E-Tec engines displayed as non-functioning prototypes; however this year BRP delivered, and Evinrude E-Tec engines were on full display in the convention center, as well as in the water.

BRP has also commenced a comprehensive ad campaign against four-stroke outboards, with the new “2>4” or “two is greater than four” campaign. BRP handed out DVDs to select press members at a press conference underscoring this new philosophy of the E-Tec’s superiority over four-stroke outboards.

It seems that BRP is committed to the two-stroke engine platform, which is great news for two-stroke outboard diehards. My experience from a ride aboard a Triton 2895 equipped with twin 3.3-litre 250-horsepower E-Tec engines proved the torque of those computer-controlled engines. Although the E-Tec is an impressive platform, I have a notable problem with BRP’s ad campaign regarding the E-Tec’s superiority to other current outboards – where are the Mercury OptiMax and Yamaha HPDI engines comparisons? The OptiMax and HPDI series of engines fall into the same weight and power class as the Evinrude E-Tec – emissions friendly two-stroke engines. I would like to see a fair comparison pitting the E-Tec 250 against similar, current production direct injected 2-stroke engines.

Regardless of which engine manufacturer is winning the horsepower-to-weight war, it is clear that larger outboard engines are here to stay, and in many cases at the forefront of marine development for these companies. Innovation and technology will continue push this market even further, and each year should bring with it new possibilities for the outboard engine platform.
