Hello all,

Im new to the boat world. I just brought my boat in to have it winterized.. I had the motor decarbonized before that was done my compression ratio was 1-90 2-95 3-95 4-90 5-90 6-93 after the decarbonized it they came back as 1-100 2-100 3-98 4-100 5-100 6-100

are these rated as good for the year? How would one go about to make them higher? What needs to be rebuilt? Are these average ratings?? :D
