Hi. Wife just bought this old Duo with a 1967 60 Evinrude. Only getting 80 to 90 psi per cylinder. Removed intake port covers and rings/pistons look like brand new...nice and free, no scoring. Been awhile since I checked compression on one of these old boat anchors. I know my gauge. Had it for 45 years.. What could be wrong here? The lady said she never ever used ethanol and it sat in storage for only 2 years. Seems to run good but isn't that low compression?
