We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common ! Just start by posting a note introducing yourself to the group, that's all it takes here (we don't ask for or retain any personal information here, because our intention is to just "have fun and share information".
The first engine of this family, introduced for the 1962 model year as an option on the Ford Fairlane and Mercury Meteor, had a displacement of 221 cu in (3.6 L), from a 3.5 in (89 mm) bore and 2.87 in (72.9 mm) stroke, with wedge combustion chambers for excellent breathing. An advanced, compact, thinwall-casting design, it was 24 in wide, 29 in long, and 27.5 in tall (610 mm × 737 mm × 699 mm). It weighed only 470 lb (210 kg) dry despite its cast iron construction, making it one of the lightest and most compact V8 engines of its class. Although all of the 1962 through 1964 221-289 engines used a five-bolt bell housing, the block mount pads varied in length between the 221, and the 260-289 motors requiring different motor mounts to be used.
In stock form it used a two-barrel carburetor and a compression ratio of 8.7:1, allowing the use of regular (rather than premium) gasoline. Valve diameters were 1.59 in (40.4 mm) (intake) and 1.388 in (35.3 mm) (exhaust). Rated power and torque (SAE gross) were 145 hp (108 kW) at 4,400 rpm and 216 lb·ft (293 N·m) at 2,200 rpm.
The 221 was dropped after the 1963 model year.
So would have been made in 62 or 63...though they could have used it in a boat that was built later.
