Got a question for anyone familar with small Greymarine engines or general gearheads. I am part owner of a 1917 launch that was repowered ages ago with a small Grey four. Anyhow, I found it has two broken valve springs. I am running into some difficulty finding parts sources. Anyone have one in their back pocket? What I am thinking as an alternative is to take the springs to an engine builder to see if they can match up to something. I can't believe they made their own springs. I think it is a marinized Continental. What you say, Fred? Rick D.
