200 2001 Johnson compression

[redfish]

looking at a 2001 hydra sport. It has a 200 HP Johnson with 440 hours on it.
the starbord side compression is 90 psi and the port side is 80 psi. thats less than 10% difference. but seems low. what do you think ?
Thanks

It is a rule of thumb, anything below 100PSI is bad.
