I have 1986 Merc 35. When I got it back from the shop for a broken shift shaft and motor mounts, I realized they did a compression check. The shop I take it to does compression checks on any engine brought in, not matter what is wrong.
Cylinder 1 = 160
Are these good numbers? What are they theoretically new?
Do these numbers give any indication of the condition of the motor?
BTW, this powers my 13' whaler!

new is 160, I guess, they are good numbers anyway, no worries.

Thanks for the replies. I've only had the motor about 2 months. Taken it out 5-6 times. runs great, just curious if the comrpession numbers were good so I would know if I need to start saving for new power!
I know anything can happen, but if I give it TLC, proper oil/gas mixture, impeller, etc, I'm hoping it should last many years.
Thanks for the replies!

Thats very good compression for a 1986.
