Like a small child, it started to "run away" but then came to its own senses, came back and seems to be operating normally with no ill effects... what gives?
Okay so details:
Yanmar YSM-8R, water inlet on Port, heel angle 15-20°?
I was sailing single handed, sailing into Muskegon channel, pointing on Starboard tack. I decided it may be a good idea to have the engine at the ready, so that after entering the outer arms I can simply roll in the headsail and head upwind, click into forward gear and into the channel. After starting the engine and assuring water was flowing out the exhaust properly, I continued sailing along merrily. Several minutes passed when engine revs started climbing, I quickly blamed the dog, (Bear has earned a reputation for laying on the throttle) then confirmed the throttle was in idle position. Immediately revs continued to climb quickly along with some sheen on the water behind the boat from the exhaust and a HUUGE plume of white smoke. The engine stop cable had no effect...$H&%!@
I quickly set about getting the boat flattened to secure the headsail and allow the main to flog while finding a shoe or suitable air block in effort to stop this runaway before imminent self-destruction. Shortly after turning upwind and furling the headsail, the engine returned to idle speed and the engine stop cable did indeed stop the engine. ?huh?
I had to restart the engine to get through the channel, and everything seemed FINE. Afterwards I checked oil level: EXACTLY on the line....Startup results are the same, and everything appears to operate just fine.
...wayward child, an engine that doesn't like to sail and wants more attention, mixing elbow? :O)
provinence of the engine is unknown, and I must admit attention to the little engine that can is limited to annual impeller and lubricant changes. Our usage is very limited, approx 5 gallons of diesel in a given year, preferring the white dacron genny to the iron variety.
