Compression test

"I ran the compression test. T

"I ran the compression test. The only tester I could find within a hundred miles is pretty old. The compression was consistent but low 75 - 80. My mechanic buddy, Oscar, and I both felt that the tester was off because the compression was the same across the board.

Opinions anyone? Can the compression go low across all four cylinders like that?

2001 Yamana 115hp fourstroke motor."
