Engine compression test ?

bigdog · 03-07-2012, 09:31 AM

Can someone on the Forum explain tgo me, how an engine compression test is performed? For Outboards, as well as I/O's.

I know specific tools/gauges are required, but can you use same tools, to perform both type of tests? Anotherwords, can the same test gauge be used for both type of motors?

This is all new to me, and just want to know the fundamentals, not that I will be perfoming these tests myself. Inquiing minds want to know !

Thanks,
BD
