I have a 1990 50hp Evenrude Tracker that is on my 1990 tournement v17 bass boat. I never fogged the engine when i put it away for the season on November 5th. I really didnt do anything because i had a new born baby in the house and was focusing on other things at the time. I will be back on the water in April. What should i do before starting her up in the spring? Your opinion would be greatly appreciated.
