    2004 Johnson/Bombardier Compression

    I'm looking a purchasing a newer boat. I compression tested it tonight the numbers are looking at motor from behind: top right 125 Middle 122 bottom 110: top left 115 middle 115 bottom 102. Tested a second time numbers were: top right 120 middle 120 bottom 110: top left 114 middle 114 bottom 101. I'm no mechanic. Can someone give me some insight to these numbers and if I should run while I still have my money lol
