exhaust Manifold for Yanmar 3QM30F

[Morgan3820]

Does anyone have a source for an exhaust Manifold for Yanmar 3QM30F? Marine Diesel Direct has them for $730 which is cheaper than a new engine but I thought that I would ask the Community for a less expensive source or even a used one, you never know.

You want to try the price for a Volvo. I wish I had a Yanmar.
