I have a customer that brought me his boat with twin Yamaha Engines and wanted it gone through from A-Z . Says he just bought the boat and it has been sitting for 2 years.
I checked compression fuel and spark, all good.
Scanned both engines for codes, no active faults.
Stbd engine number 6...
A customer brought me his boat after it was sitting in a barn for 2 years. 2006 Mercury 4 stroke EFI
I drained all the gas from the fuel tank and the VST, motor was infested with more mud dauber nests than I have ever seen, cleaned all of them out. (as good as I could)
Brand new batteries...
