Just purchased an alumacraft magna 165cs. The boat has been in the shrink wrap and stored outdoors for 5 + years. What should I be concerned about as I try to bring this 75 hp motor back to life. I was told that this was a good running engine that was professionally put up for long term storage. 5 years seems like a long time and I would like to be a bit proactive and do the things that will better my chances for success.
