Identification of Old Evinrude Engine

[JJ Jones]

The model number is 75583 S; Serial Number is E01 398.<br /><br />I would like to know what kind of engine do I have (I think 75 hp) and if repair shop manuals exist today for purchase. <br /><br />The engine runs, but is using too much fuel. When the spark plugs are pulled they are wet with gasoline. <br /><br />Does anyone know what type of spark plugs I should use with this engine? <br /><br />Thanks for anyone's help.....JJ Jones

Welcome to Iboats, JJ Jones.<br />Evinrude Model 75583<br />Year: 1965<br />HP: 75<br />WOT RPMS: 4500<br />Displacement: 89.5 cu.in. = 1466.6 ccm<br />Cylinders: V-4<br />Weight: 226.5 - 240.5 lbs. = 102.7 - 109.1 Kg<br />Gear ratio: 20:23<br />Spark plug: Champion J4C gapped at .030 (was J4J)<br />Fuel/Oil mix: 50:1 87 octane gas to TCW-3 rated outboard oil.<br /> Picture<br /> <br />Sounds like you need to rebuild the carburetor, so you've got the right plan - getting a manual. Iboats sells aftermarket repair manuals, or you can order a reprint of the original factory service manual from one of the following places:<br />TheOutboardWizard<br />Mastertech<br />Marine Engine<br />Ken Cook <br />The factory manual is more expensive, but its technically superior to the aftermarket one. <br /><br />Parts for your engine are available from many sources, Iboats being one of them. You should have no trouble finding a carb kit. But try to get one from your local Johnny/Rude dealer. If your carb has a cork float in it, it should be replaced with the new style plastic float, and that only comes in the OEM kit.<br /><br />Good luck!
