So here's the story: My father-in-law passed back in January and I've been helping my mother-in-law cleanup her property and sell things she has no use for. They have this 24 foot pontoon boat that has been sitting for 5 years! It has a mercury force 75HP outboard and I don't know much about them. If I change the oil and filter, bleed the gas lines and put in a new battery should I give it a try and turn it over? or do you think that would do more damage? I already have my own boat but she gave me this one also and I'd like to keep it since there were alot of great family memories with him and the boat. Advice please?
