How to perform a compression test on a 2004 Yamaha 200 HPDI my eng runs good when I did the test the compression was only 60 psi

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

My eng runs good but I wanted to test it for piece of mind hrs are about 475

Mechanic's Assistant: Is there anything else the Marine Mechanic should be aware of?

Top RPM is 5100 and I think it should be about 5600 on a 22 triton LTS bay boat prop is a 15 1/4 19p
