    Default "I'm servicing my 1990 150

    "I'm servicing my 1990 150 Yamaha outboard. Upon removing the head covers and the heads I've discoverd a large amount of saltwater induced scale or saltwater deposits clinging to the water jackets around the cylinders. Has anyone had any luck with any liquid scale disolvers like CLR or anything of that nature.
    I also think I've found why I'm overheating at high RPM's
    Thanks Gene"

    A "professional" is someone who gets paid for their work - it doesn't necessarily mean they are good at it :)
