New to boating.. have a 5.7L alpha one 1990. Oil changed/winterized end of 2005 season. Boat not used in 2006, except for the demo trip I took with the owner. The boat was winterized at the end of last year, but no oil change. My questiosn: 1. Should I change the oil again, 1 30 minute trip from 2006. 2. If I change the oil (i'll do myself) do I need to change the oil filter? Not sure if I can do that, in fact, can't even find it! I plan on changing the lower unit oil. Thanks for the help! Water pump/impeller changed end of 2006, so I'm good there. Any other tips appreciated.
