here is the motor and the head......model and serial is 6h2L450334.....60FETO.......also there is a (N) located in the bottom left hand corner of the serial plate. it is a direct injected model, tilt trim, ran beautifully until the oil injection stopped working and cooked the motor. needs to be rebored to 40,000's of a mm but need to find out if they make the oversize pistons that big...i found a site that sells new power heads with pistons but again no 60HP 1984!!! hope this info helps. also wondering why the have the 40 50 70 and 90HP models listed but no 60? unpopular model? any advice/info would be greatly appreciated.

Maybe it is a 70 HP marketed as a 60 for your area.-----Check with a dealer.
