So the boat was in storage from September 2014 to May 2017.
I winterized it per the Mercruiser manual for a heat exchanger equipped 350 MAG MPI back then, and it started after about 2 seconds of cranking today. Phew.
So now I need to re-winterize it. This year was mostly completion of the fuel tank area and fixing some bilge plumbing, and some power washing.
I have a few questions:
The engine is a 2004, with a new lower unit circa 2007. I think it has been in fresh water once since 2007, and never in salt water since then. I winterized the seawater side with polyethylene glycol in 2014.
It has the closed cooling for the engine. But I am concerned about the rubber parts for the exhaust and the I/O bellows. How long do those rubber parts and the manifolds last? I don't want to hydrolock something that runs so well.
