I just bought a 1997 , 75HP elpt , Force by Mercury motor. Is this motor a mercury or a Chrysler? Who manufactured the motor? The motor appears to be in good condition, but is it worth the trouble of installing on my boat? NADA list this motors value at less than $400.00. NADA list the Mercury 75HP same year model for about $1100.00 Their must be a reason. I would appreciate any help. thanks, Chodie
