I have a 1986 4 cylinder Mercr
I have a 1986 4 cylinder Mercruiser 170 that will start when cold fine but when I shut it down after the engine has warmed up it won't start and barely turns over. The voltage regulator puts out 13-14 volts when engine is cold but goes up to 17-18 volts as the engine heats up. I don't know if this is just a voltage regulator problem or if the high output voltage is affecting the solenoids and or starter. Can anyone give me any guidance on this. The VR costs $400 and I don't want to just start replacing parts if I don't have to.
