[C320-list] Yanmar 3GM issues

[Louis Friedman]

Thanks for the tip Doug. I did use those oil sorb pads, worked quite well.
The engine stars better now but I find I still need to pump the butterfly
pump about 40 times to get it going. there must be another leak of some
kind somewhere. At this point I'm dealing with a steering issue though so
I'll get back to the engine later.  thinking now I should have bought a
newer boat!
