I just bought a 24' 1990 sunchaser with a 90 hp Mariner that needs to be replaced (quoted $3500 for repair . My local choices for motor replacement I've narrowed down to a 2012 60hp mercury bigfoot with 100 hours for $4500, a 2013 90hp Etec with 300 hours for $5900 or a brand new Suzuki df50atl with 6 year warranty for $5900. I use the boat mostly for slow cruising as my kids are too young to tube or ski. What would you go with and why?
