    Hello,
    I just changed my 9 amp stator (CDI 173-3672). I have dual power packs on my (Evinrude) E88MSLCCC. I have both a Voltage regulator 511404 and a rectifier 583408 on my motor. However, to play it safe due to its age I want to change out the voltage regulator (511404) but its obsolete.

    My voltage regulator has 3 wires. (Brown, Yellow, and Black) I looked on Marineengine.com and their diagram is pointing to a regulator that has 5 wires. On Ebay I found a 581736 that looks identical to my old unit, but the wires are Purple, Yellow, and Black.

    Could I use the 581736 in lieu of the 511404? Is it 10amps, will it damage my engine or new stator? I could not find specs anywhere. Any help would be greatly appreciated!

    if you have a few electrical loads and or dont run WOT all day I wouldnt bother with the regulator as the output is low.
    That regulator you mentioned is only a halfwave version not a full regulator which became the water cooled one same as the looper v engines
    Cant damage your stator, the regulator just shorts to ground to control voltage.
    Do you have a voltmeter on the dash?
