Try another gauge. Also there need to be a schrader valve in the gauge set up somewhere. I remember Harbor omitting that on some of the later testers. Also, check it on another ski if possible.

The rings are probably not worn in yet you can't break an engine in on the hose either in case you didn't know

 

[Bryan1102]

Just a couple starts before going to the water you know

Yeah but you have to break in the new top end for the compression to come up to spec after proper break in check compression it should be right at that time

 

[Bryan1102]

What is suggested proper break in?
