ABOCAfter bottom dead centerACV: Alternating current voltageAlternator: Electrical generator producing voltage alternating currentBBOC: Before bottom dead centerBOC: Bottom dead centerBTOC: Before top dead centerBow: The front of watercraft C: Celsius CC: Cubic centimetersCOl: Capacitor discharge ignition Ignition system which stores voltage generated by the stator plate exciter coil in capacitor or condenser (in COl box) At the proper moment voltage generated by the stator plate pulser coil closes an electronic switch (thyristor) in the COl box and allows the voltage in the capacitor to discharge into the primary windings of the ignition coilCI: Cubic inchesCondenserCapacitor: storage reservoir for electricity, used in both E.Tand COl systems Crankshaft Run-Out: Run-out or "bend" of crankshaft measured with dial indicator while cran kshaft is supported between centers on blocks or resting in lower half of crankcaseMeasure at various points especially at the PTO end DCV: Direct current voltageDetonation: The spontaneous ignition of the unburned fuelair mixture after normal ignition spark occurs Piston looks "hammered" throughrough appearance around holePossible causes: 1) Compression ratio too high for the fuel octane; 2) low octane fuel; 3) over-advanced ignition timingIII IC I'D
