Compression Test Results??

[SAGE9]

I had a 99 Johnson Ocean Pro 150 2 stoke, oil injected compression tested. This is not the FICHT model. Does these results seem O.K.?<br /><br />115 105<br />103 105<br />103 105<br /><br />Thanks much.

They are within roughly 10% of each other so are ok. If you haven't decarbed the engine you might try that and then retest. The lower cylinders may come up some. You might also retest the 115 cylinder. If the engine was cold you might try retesting all cylinders with the engine warm. You would then have a very complete set of numbers. However, as it is, the numbers are ok.

We ran the engine first during a sea trial and then did the compression test after she was pulled. Thanks for the feedback its much appreciated.
