Well, things didn't go so well on the sea trial on the 460 this past Wednesday. Things started off rather well. The boat cosmetically looked much better then we were anticipating. Canvas looked pretty good, cockpit vinyl had a few cracks but overall it looked better then we were expecting. Cockpit carpet was missing a few pieces and the boat just really needed a good buff, wax and detailing.
The engine room was pretty rough, lots of rust and dirt. A typical un maintained boat sitting in salt. It started out a little bad when the generator would not fire up and the starboard motor dragging when we went to fire it up. The generator had just had a new stater installed a few months ago and looked like new on the front side. However, aft was covered in rust from a leak that went un checked for some time.
Here is when things started to go well and turned to **** in a hurry. We fired up both motors and everything looked good. Great oil pressure, exact same RPM's at idle and perfectly synchronized. She went into gear nicely and away we went. Nice and smooth with no vibration or cavitation. The temp started to climb a little faster on the starboard side motor. The disial surveyor wanted to shut her down so we could get some readings and our oil samples. Now we new that the last time the captain had the boat out, the starboard motor starting to get hot and was shut down. When we backed the boat down for the surveyor to do his thing we popped the engine hatch and steam had filled the boat. We immediately found the cause. The starboard exhaust manifold had a large crack across the top. Upon further inspection the surveyor found a pool of oil that appeared to be coming from the head gasket.
Their is no chance that the captain just got it a little hot and shut it down. He had to have boiled it over real good in order to crack that manifold and pop that head gasket. I think he must have been hoping nothing blew. If that engine got hot enough to crack that manifold then the chances are that the magnesium pistons are damaged.
The diesel surveyor is confident that the starboard engine will need replacement. Along with all the hoses, all the motor mounts both starboard and port. The after coolers will have to removed and boiled, the water pumps will both have to be replaced and the list goes on and on.
We are hoping to have a complete list and price on the engine work and everything that has to be done in the engine room. His guess is 40 to 50k. This is a good lesson on maintance. This boat only has 440 hours on the Cummins. It is owned by a very wealthy man that could have easily had the right person maintain the boat. What a shame.
We are still waiting to get the report on from the other surveyor. A few things that he had mentioned were. The electric platform motor was covered in rust and would need a complete rebuild, the shore power cable was toast, the shower heads would not work, the batteries all needed to be replaced, the contact for the central vacuum was missing, just some little stuff like that. I haven't got the report yet.
The owner of the boat did ask if we were still interested in the boat if we could work out the repairs and numbers.
