If there is a lot of fuel, you may want to clean it instead of disposing. Also there are additives that will take care of the any water
in the fuel. Your tank may have a tap for draining the bottom of the tank - where any water
I would drain a small amount of oil
from the bottom of the oil pan. If no water, then I would use that oil for the first warm up and later change the oil and filter.
My boat was sitting for 5 years in Western Canada
when I bought it. 2 mains, 2 generators. I cleaned the diesel
by pumping fuel thru the existing racors with 30 micron filters and after a period of time changed the filters to 10 and later 2 microns. I also installed a algae-x fuel conditioner. The fuel went from dark amber to clear and when I entered the tanks
years later, the tanks
were clean. The engine
oil showed no sign of water so I used that for start up. Later when changing the oil, I opened the filters looking for metal and also found no water.
Check Make sure the fuel system has no air. Go thru the bleeding process. Have spare fuel filters.
If the engine has a block heater, run it until the engine feels warm. If no block heater, try to find a way to heat the engine compartment. Engines sitting for long periods in cold climates often have their rings contract
. Expect some smoke until the engine warms. Open the thru hull
Make sure the cables
to the starter and ground are making good contact.
Check the intake air path. Know how to stop the engine before you start it.
The engine should start. Try to avoid using ether. Ether greatly raises compression
and when using too much can break rings.
Make sure your salt water
pump is moving water. Plumbing
going to and from the pump should be noticeably colder. Check your discharge. Look for leaks
. Your rubber hoses probably should be changed.
in your water pumps may fail. The rubber parts
get hard with age. I had two fail on my engines and replaced the others.
When I was much younger I was part of an operation that took mothballed ships and boats and returned them to service
. We never disposed of fuel, even bunker oil mothballed for 20 years. It was rare to find one with all liquids completely drained. Usually just the water.
