Boats do take time and money to own. DIY helps but you still need a good pro for some things. For a good time try changing the impeller (cooling pump) in a Malibu v-drive like mine. Someone engineer stayed up late figuring out how to hide the darn thing where can hardly see or reach it. A std maintenance job not for the faint of heart. That said the bad stuff fades fast when you are cruising along. Best advice I can give is take a safe boating course, get out on a quiet day and practice your skills until you know yourself and your boat. Then have fun!
