    Re: 90 Etec Corrosion from Stainless propeller???

    Bopen your going to need wadders when u put the new engine in salt water not because the nippers will bite you're toes but your pearly whites will erode due to the fizzyness from standing in salt water only playing

    I would get someone to look over the boat especially if someone has earthed a negative to the hull for the return power wires

    My evinrude had two in the powerhead....

    Can anyone confirm this???
    It cost me $16,000 to replace the whole motor.
    Perhaps tilting the motor so the prop and leg was out of the water for the 1,200 hours the boat was anchored might have helped.

    Nope. Tilting your engine wouldn’t have removed the salt in the power head that built up over 13 years.
