MY 33 ft CheoyLee has a Yanmar
3GM30F diesel engine
. When we were wrapping up and motoring into harbour for haul out
, the mixing elbow
blew out. I had already ordered the replacement, so it was not a big surprise.
It was a few days before I was able to work on the boat in the yard. The engine
was not able to turn over on the starter. I determined some water
was ingested by the engine through the intake. I sprayed WD40 into the intake and opened the decompression levers on the three cylinders.
I put a 3/4" drive socket on the crankshaft and rocked the engine back and forward. I was able to get a few degrees of movement so I backed it up and tried the starter. Engine turned over fine. I removed the rocker cover and checked all the valves were opening and closing. The rocker area was very clean, no sludge, good to note.
I dropped the compression
levers one by one and started the engine after a few attempts, and idled it for a few minutes, then changed the oil
So the engine is fine. I will not be using the boat until after hurricane
season. Can I get recommendations one how best to leave the engine. An experienced friend recommended squirting oil
into the cylinders to ensure the residual salt
does not freeze the rings to the cylinders again. Any thoughts on that?
