Re: What year is it?
Model #7522 Evinrude:<br />Year: 1957<br />HP: 7.5<br />WOT RPMS: 4000<br />Displacement: 12.4 cu.in. = 203.2 ccm <br />Cylinders: 2<br />Weight: 59 lbs. = 26.8 Kg<br />Propeller: 8 x 8 1/2 , 2 blade <br />Gear ratio: 15:26<br />Gas/Oil ratio: 24:1 (follow it on this engine! It likes it's oil)<br />Spark plug: Champion J6J (Now a J6C)<br /><br />3 blade props are less efficient due to their small blade are. They are better at pushing heavier craft though.<br />A 3 blade propeller was never offered on this engine, so I doubt you'd find one anyway.
