I am looking at a new boat. I found 2 2009 Lowes aluminum 17.5' fishing boats which are equipped basically the same. One has the 75 hp 4 stroke and the other has the 90 hp 2 stroke Opti-max. Which would be the best way to go? Is the high tech 2 cycle gonna be a pain in the long run as far as maintenance goes? Price on both boats is within $100 of each other.
