They’re clean and compliant with the toughest 2006 emissions regulations. They’re powerful, quiet, and unbelievably smooth. You could say these Johnson® four-strokes were designed with a little bit of everything in mind. The kids. The weekends. And, of course, all the fish in the sea.
That kind of versatility comes from a host of features that make Johnson four-strokes the best-in-class. Four-cylinder, in-line, single overhead cam power plant for smooth power on the 60 and 70 HP models; digital sequential multi-port fuel injection for excellent throttle response and fuel economy; the Johnson pulse-tuned manifold for truly inspired acceleration; solid state ignition for sure starts; and power tilt and trim for greater performance and control.
The 50 and 40 HP have the same list of outstanding features but use a powerful 3-cylinder, in-line, dual overhead cam power plant. It’s never been so easy to befriend an outboard.

**Power Ratings: Johnson® outboards are power rated in
accordance with NMMA procedure using the International Council on Marine
Industry Associates (ICOMIA) standard 28/83.
Remote Control: Not supplied with the engine. †Only standard if you use
††Super S.L.O.W.™, Speed Limiting Overheat Warning System.
Accessories: Steering Connector Kit.
Oil Injection Tank: Not Supplied with engine.
Trim Gauge and Harness: Not supplied with engine.
Propeller: The propeller that comes with your new outboard (supplied with
40 HP and smaller models) is designed to give you the best performance for the
majority of applications and uses of that outboard. For special applications or
uses, your dealer will help you select a propeller that may be different from
the one that comes with your motor. On models through 40 HP, you can, at the
time of purchase, exchange the propeller that came with the motor for another
prop of similar value. For models of 50 HP and larger, as well as for special
needs, a wide variety of props are available at extra cost. A full line of SSTII
(15"-23"), Raker®, Viper™ and Renegade® propellers are available
for counter-rotation models.
Maximum Boat Horsepower: By law, most outboard boats up to 20 feet in
length must carry a plate certifying the maximum horsepower permitted under U.S.
Coast Guard regulations.
Fuel Facts: Use unleaded automotive gasoline with an octane rating equal
to or higher than 67 pump-posted for 25-30 HP models, 87 pump-posted for 40-175
HP models. Using unleaded gasoline that contains methyl tertiary butyl ether
(MTBE) is acceptable ONLY if the MTBE content does not exceed 15%. Using
alcohol-extended fuels is acceptable ONLY if the alcohol content does not exceed
10% ethanol or 5% methanol and 5% cosolvents (for further information see your
Operator's Guide).
Note: Please follow the lubricant information in your Operator's Guide.
Evinrude/Johnson XD25 formula outboard oil is recommended for Johnson outboards.
Warranty: A full statement of the coverage terms and conditions applying
to the Johnson outboard Limited Warranty has been furnished to Johnson dealers
for inspection at the point of sale and is included with the Operator's guide
furnished with each motor.
Specifications: In furtherance of our policy of continual product
improvement, we reserve the right to discontinue, substitute, change or improve
the design of any outboard motor at any time, without assuming obligation to
modify motors previously manufactured. The information in this brochure is based
on the latest specifications available at the time of printing.
Note: Information contained in this publication reflects domestic U.S.
product availability. Product availability and warranty may vary outside the
U.S.
