[C320-list] Engine Oil

[Joseph Aberdale]

I changed my engine oil and oil filter last October when I winterized  
the boat.  I checked the oil after I started the engine recently and  
the oil was a very deep colored black, not the look of new oil. Is  
this normal after a 6 month winter layover?  Should I change it again?

Also, is it worth it to purchase an impeller puller?  Does it work well?

Thank you for your thoughts.
