I know a couple guys on here must know somthing about these older motors, i just picked up a 73 25hp and after the first run the motor would cut out and often die after running wide open for 3-5 min. After taking off the cover i noticed coil packs had cracks so i replaced both, i also just replaced thermostat and impeller but it doesnt seem to have any water coming out the exhaust outlet/ water outlet? any ideas?
