Yanmar 100Hp on Sailboat Irwin 52, stalls when shifted to gear on idle speed reverse or forward. Need to accelerate it to prevent stalling and faulting. Have checked Fuel flow and filters well all clean, Also control cables and idle RPMs OK at 800 RPM. Yanmar technician checked it could not find solution to problem. Thank you for your ideas and help. Also, engine wont show the problem when cold only when hot after about an hour running or so.
