Yamaha's New 25hp Four-Strokes

Marine Group introduced two new 25hp, four-stroke outboards, the F25 and the T25, back in February. Great for small pontoons, these versatile outboards rival Yamaha's two-strokes for top-end performance but offer the fuel efficiency and smoothness customers have come to expect from a four-stroke.

"Putting a four-stroke 25 in our current lineup is really about meeting the needs of our dealers in key regions of the country," said John Rigsby, Yamaha Marine Group National sales manager. "There are applications, particularly in the Midwest, where our F20 is just not enough outboard and our F40 is too much. Yamaha dealers asked for this addition to our line, and we heard them."

The F25 and its sibling-the high-thrust T25-both use a 498 cc two-cylinder, single overhead-camshaft powerhead. Its block and cylinder head are all new, and it shares connecting rods, pistons and valves with the Yamaha F60 powerhead. The F25/T25 powerhead features a new tuned long-intake track manifold, micro computer controlled ignition and Yamaha's PrimeStart system for outstanding fuel efficiency, easy starting, fast acceleration and excellent top-end speed.

Like the F20 and F40, the F25 and T25 use an integral engine monitoring and warning system and Yamaha's Ultimate Corrosion Protection System. The high-thrust T25 features a standard Yamaha Dual Thrust propeller, a high 2:42 to 1 gear ratio, electric start and remote control, making it ideal for small pontoons.

The F25 is available with shaft lengths of 15 inches and 20 inches. The T25 comes with a 20-inch shaft. Both sport new graphics and a lower-profile cowl.

Yamaha Marine Group, based in Kennesaw, Ga., supports its 2,200 U.S. dealers and OEM partners with marketing, training and parts for Yamaha's full line of products and strives to be the industry leader in reliability, technology and customer service. Yamaha Marine is the only outboard brand to have earned NMMA's C.S.I. Customer Satisfaction Index award every year since its inception. Visit for more information.

With the preview of its new 2010 DF60 four-stroke outboard at the Miami International Boat Show, Suzuki Marine proved that less can be more-at least when it comes to advanced four-stroke outboard performance.

This streamlined and powerful new 60hp four-stroke is more advanced and more fuel efficient, with its target weight expected to be far less than many competitive models. Smaller, lighter and more efficient than other four-strokes in its class, the new Suzuki DF60 will still pack a solid punch and will be an ideal fit for a wide variety of boats-especially in the pontoon market.

"Our engineers are constantly exploring new technologies to discover ways that we can make our outboards even better," says Larry Vandiver, marketing director for Suzuki Marine. "This new DF60 is a perfect example of Suzuki's commitment to developing new generation outboards that aren't only better than the competition, but leaner, meaner and stronger than our first generation four-strokes. Over the past decade, we've built a reputation for four-strokes that deliver the fuel efficiency, clean operation and reliability boaters expect, combined with surprising performance. Our new generation four-stroke outboards-the DF 70, 80, 90, and soon to include the new DF60-will keep this reputation alive and keep Suzuki ahead of the pack."

Always a central focus in the design of any Suzuki motor, fuel efficiency is further enhanced by Suzuki's new Lean Burn Technology, a feature that predicts fuel needs according to operating conditions and allows the engine to operate on a very lean air/fuel ratio. The new Suzuki DF60 is expected to provide the perfect balance of efficient operation and top-end performance on a wide range of hull sizes and styles.
