1.  1953 Evinrude 25 HP Big Twin.  The chrome piece that holds the Evinrude decal is not a separate piece.  Instead it's part of the cowl but just not painted.  The  1954 has a separate chrome piece riveted on.

2.  Another 1953 Evinrude 25 HP Big Twin.  Notice the notch in the metal just below the cowl. The 1954 motor doesn't have that notch.

3.  1954 Evinrude 25 HP Big Twin.  Extremely easy to find.  Along with the 1954 Johnson, probably the easiest motors to find.  Millions of them were made and sold in toy and hobby shops.  They were also given out as Christmas gifts to OMC employees and dealerships.  The cardboard box is a replica of the shipping carton that the motor came in.  Thanks to Joe Cain for the first picture.

4.  1955 Evinrude 25 HP Big Twin. Called the "Aquasonic" because of it's side decal which has a flying bird and the word "Aquasonic" under it.  The white paint is of poor quality and chips very easy.  The blue is of better quality. Many are repainted or touched up.  Neat looking box with the words "Whispering Power" on it. This motor has a special significance to me since the real motor was on my father's 1952 Lyman 16 foot outboard runabout when I was a kid.

5.  1956 Evinrude 30 HP Big Twin.  A common motor.  Very easy to find along with the Johnson version.  Often found on Fleetline boats as part of a combo package. Notice the decals are block letters and above the black middle strip.  The front face plate is white.  Small red emblem on the side.  You can usually find these pretty cheap.  This motor had several small variations to it.  For example, some of the white bands were screwed in on the back.  Thanks to Joe Cain for the first picture.

6.  1957 Evinrude 35 HP Big Twin. My favorite as it's the first toy outboard I had as a kid.  Very common motor.  The "Evinrude" is in script which is an easy way to distinguish it from the others.  The white paint often has chips in it. The motor came with a white plastic K&O stand, instructions, the electrical connections for the boat and the box. Interesting note: The picture on the box is NOT of the Evinrude Big Twin 25 HP!  It's a picture of the 1957 Evinrude 18 HP Fastwin!  I wonder if K&O was going to make the Fastwin instead of the Big Twin?  Thanks to Joe Cain for the first picture.

7.  1958  Evinrude 35 HP Big Twin. The first year they made two motors for a manufacturer.  Very rare.  Only four and a half inches tall.  The transom brackets are poorly made and break easily if you tighten the screws too tight.  Darker blue than the 56 and 57 motors and block letter decals in the white in the middle of the cowl.  Nice colorful box.  Thanks go out to Joe Cain for the first picture.

8.  1958 Evinrude 50 HP Starflight.  Not rare, but sought after because of it's unique design.  The first V-4 by OMC and says "Four Fifty" on the front decal.  A great looking motor.  It's often called the "Fat Fifty" because of it's shape.  There are two metal emblems on the back of the cowl that have a tendency to fall off so it's something to check for if you find one.  Thanks to Joe Cain for the first picture.

9.  1959 Evinrude 35 HP Lark.  Not rare but not common either.  Can be bought at a reasonable price because collectors don't seem to love this motor. I'm not sure why this is since it's a pretty neat looking motor.  1959 was the 50th Anniversary for Evinrude so this motor had special paint  colors and decals.  First year of the Evinrude Lark.  Thanks to Joe Cain for the first picture.

10.  1959 Evinrude 50 HP Starflight.  50th Anniversary model with the special paint job.  Again, not loved by collectors and usually sells for a reasonable price.  Check these models carefully when buying because there are several tiny metal emblems that have a tendency to fall off.

11.  1960 Evinrude 40 HP Lark II.  EXTREMELY rare.  One of the hardest motors to find.  Always seems to be one of the last three motors that collectors are looking for.  The Evinrude decal on the side never seems to be straight for some reason.  Be careful with the front decal, it has a tendency to rub off!

12.  1960 Evinrude 75 HP Starflight.  Very rare, but not as rare as the 40 HP version.  Unique looking.  The side plate that holds the Evinrude decal never seems to look right because the word "Evinrude" is often crooked and not straight.  Be careful with the front decal, it has a tendency to rub off!

13.  1961 Evinrude 40 HP Lark III. Very rare, but not as rare as the 1960 and 1962 versions. Notice how the decals yellow over time, that's not a golden background but a clear background that has yellowed.  The transom brackets are very fragile on this motor.  If you can't afford this metal one, K&O made an excellent plastic version of this motor that you would be hard pressed to tell the difference from 5 feet away. Thanks to Joe Cain for the first picture.

14.  1961 Evinrude 75 HP Starflight.  Very rare.  Neat looking motor.  Looks a lot like the 1962 but the side decals are different and this one has a neat chrome wing with a red accent on the side of it.  It's an impressive looking engine with a dark charcoal like paint job.  Thanks to Joe Cain for first two pictures.

15.  1962 Evinrude 40 HP Lark IV. Extremely rare.  Last year for the K&O metal motors.  Has very weak transom brackets which tend to break.  Side decals have a tendency to fade if exposed to the sun.

16.  1962 Evinrude 75 HP Starflight. Extremely rare but not as rare as the 40 HP version.  Often has decal problems with the side decals.  Because of it's large size the paint can be chipped easily.
