Hi guys, I bought a used sailboat this past spring with an Atomic 4 that had been sitting idle for several years. Although the engine works, white smoke comes out the exhaust, oil pressure is low (Cruising 20psi, 5 - 10psi at idle), and smoke comes out the oil intake at higher speeds.
I ran the motor several hours trying to burn off any "winter oil", but the problem persists.
I did a compression check and all four cylinders are right around 100psi. If the compression is good, does that mean the oil rings are fine? Or do all signs point to oil ring damage?
