Some of you might recall I had some shifting issues last summer. My season ended early when my daughter had a bad bike wreck and then my dad suddenly passed away. I have not seen my boat since the end of August. Anyway, I went today to do my usual start of the year routine. When I drained the outdrive (VP 290 DP), out came the water and then the terrible burned smell from the oil. Not good. What is the most likely cause of this. It was not a case of bad or missing o-rings on the fill cap or the plug at the bottom. What are the chances I did permanent damage? How will I know? What do you recommend? Thanks for your help in advance.
