One more thing to add to the list is fluid samples...I know many do it already ( I do regularly) but a good idea for anyone's winterization list to take oil samples after running antifreeze and shutting down.
Oil analysis for engines and genset
Optional transmission
I have typically done oil samples every 50 hours and before winterization. I am contemplating also doing after spring commissioning just to make sure all is well after winter layup.
My experience is the oil can probably last 400+ hours but I haven't pushed it that far yet. I put almost 300 hours on the boat this year and that was an all time record as a result of my trip. Normal years I am around 100-150 depending on trips. I would probably change the oil at least every two years any way regardless if low hours and of course sooner if an analysis indicates. I found my oil was practically new at 200 hours Probably can get 400 hours based on the trend.
