On our 1991 Hunter 28, the head plunger became difficult to pump. We were spending a week in the Sacramento River Delta, and away from our regular service areas, so I put a little vegitable oil down the head and it helped. It immediately freed up and seems to work fine. This was before I read your article not to use oil.Is there any lubricant which works best without putting a film on the tank?
