    compression numbers on a 1997 Johnson Venom 200 (carburated

    I'm looking at this motor and wondering what good compression numbers would be? also any input on the motor would be appreciated. I no the numbers can vary by gauge and motor and they need to be within 10% but whats too low? motors only been in fresh water.

    90-100 PSI range is norm for that vintage motor. 0 is too low.
