Well, we are still feeling sick about our engine. The tech who rebuilt the Yanmar traveled to the boat yard to see the way it was acting. He looked over the installation and saw how it was performing and immediately asked to have it pulled and he would take it back with him. The yard pulled the engine and put it in his truck and it was opened up back at the shop.
My husband traveled to NJ to see the engine apart. Findings are three bent rods due to fluid (water or fuel) incursion. The problems from our point of view is how did this unknown fluid get in.....
The shop tells us we did not do anything wrong.
Funny that when they rebuilt the engine, they did not replace the rods. They say they were in "spec"...sadly they are no longer in spec.
The next thing is the engine will be returned and will go back in the boat. We are so nervous that this will happen again. No one has resolved how this has come to happen so we do not know if the installation was correct or incorrect.
My husband was aboard during storms that brought surge to ensure dock lines let the vessel sit in the slip without tension down at the stern. We have sailed in some brisk breezes but can not see how we could have water come in via the exhaust.
Does anyone have any ideas about how this could happen? The boat yard is trying to puzzle this problem. We think about nothing else. The re-builder gives no information other than results.
Oh yeah, when the tech came down and took the engine back, he found the transmission (that was done by another shop) was totally wrong. I do not even know what that means but the yard is going to get that resolved.
WAAAA. Sorry to cry on you all but know that there is lots of good ideas that come from this group.
Happy Thanksgiving to all. For all this trouble, we are still well blessed and will celebrate this time of year.
