150 is stock compression. however, there is a chance that your gauge is inaccurate. usually if they are 130+ and EVEN, your good to go. but 120, even on a shady gauge is low. i cant imagine it being off by 30psi. test it on another gauge and see what it comes up with. The 951's run lower compression than the smaller Seadoo engines. 130 psi is perfect on a 951 and 110 is about the bottom. Cold or hot really doesn't make a noticeable difference on the compression numbers on these.
If your oil level is full or slightly overfull it will give a higher compression due to oil coating cylinder wall and forcing oil up into the combustion chamber. If timing chain is just a little off, compression can be lower due to valves opening early but still run very well with only 110. leakdown test is a better test as far as engine condition.
