Re: Evinrude 9.5

that’s not mediocre compression. That’s actually very good compression even with a drill gun on the flywheel turning it over. Hand crank, anything north of 60 is a good motor. I’ve never seen one (and I’ve worked on about 100 of them) above 85-90…even soaking wet with fogging oil.

Dry numbers, cold, on my guage that are 65-70 yields (all things being equal) a very smooth and low idling motor with plenty of top end. They idle down so low you can just about see the flywheel turning.

Very much like the old 6hp motors when idling low (which generally are less tolerant to the abuses of high hours compared to the 9.5’s IMHO).
