    Suzuki 150

    I'm looking at a boat with this motor. The guy said compression was 200 on all 4 cylinders. I thought maybe he was lying to me as most compression tests I've seen most people mention around 120s.Screenshot_20200220-105404_Messenger.jpgScreenshot_20200220-105404_Messenger.jpg

    Compression gauges are mostly accurate, but some need to be re-calibrated. My 4 stroke has about 150. What you're looking for is variation, not to exceed 10% between them all.
    Buy your own at Harbor Fright, they aren't expensive.
