Been thinking about buying my neighbors old Starcraft boat. It has a 120 hp I/O with Merc. Cruiser outdrive. Motor has a lot of blow by with it heating up past 190 when warm and idling ( needs new impeller ? ). Out drive is almost out of adjustment grinds kinda going in reverse ) so thinking out drive is needing replaced. Leaks water ( a lot ) 5 gallons an hour. Hull is in good shape along with floor. Homemade hard top ( not bad ). $350 for boat with rusty tandam axle trailer. I am also looking at a 1974 22 ft Islander with 455 olds with berkley jet...have just seen pictures of this one but looks real nice. It has 900 hrs for $3,400. Which one would you guy choose?
