Hi all folks, Im looking for some experience Yanmar owners, about a month ago I purchased a beautiful ODay 322, with a Yanmar 2GM20F working flawlessly, a couple of days ago while returning from the sea to San Diego Bay, it was late and the wind was not cooperating at all, so I stowed sails an turned on the engine, after motoring for a while at 4-5 knots, the boat lost speed until just 1 knot, I reviewed the engine RPMs, being ok, accelerating and decelerating normally, but apparently the propeller was not getting the power and I heard a noise like if it was skidding, then I looked at the boat sea water discharge and suddenly it started to expel dirty black water for a while, so I shut down the engine, then I checked the oil and coolant, being both at the full marks and with no leakage at all.
So I hoisted sails again and managed to sail to the marina, arriving around 11 in the night.
Before entering the Marina, I started the engine again, hoping to have it available for the docking in the night, It started nicely, I put some thrust in it, getting two knots, so I decided to accelerate it more, and surprisingly it worked ok getting the normal 4-5 knots as if nothing have occurred before, no more black water, no more skidding noises.
The next morning I took it out to the bay briefly just to make a quick revision of the engine and it worked apparently ok.
Has anyone of you folks have an idea of what could happen to the engine, I would appreciate your help to get this matter solved.
