- Grand Banks 47 Eastbay FB
I'm in the final stages of taking possession of a 2005 Grand Banks Eastbay 47. The sale has closed, but there is an escrow account to address any mechanical items that arise on sea trial (New England boat, sale completed over the winter, boat going in the water this week).
On the initial out of water survey, our surveyor noted that one of the three Marine Air compressor units had browned (visually). Two of the three units had been replaced within the past few years. A technician at the boatyard evaluated the three units today and found the following (with commentary):
"Two new AC units surface temps 62F and 68F, the old unit is 95F. There is no documented specification I am aware of for compressor case temperature. The older unit will likely have a different gas (R22 vs newer R410) that will operate at a different temperature. This browning is very common; the unit is functioning perfectly at this time."
With two of the three units having been replaced already, it's only a matter of time I expect before I'll need to replace this third unit. I'm guessing this is a long shot, but if anyone has experience or documentation of the normal operating temp of the compressor, or whether browning is "normal", I'd welcome your feedback!
