Colleagues,
I am troubleshooting a 2005 15 hp 2 stroke mercury that is misfiring . Once it warms up , after 3 minutes +/- , once every minute o more i get a misfire. Also noticed that is still there at higher rpms . I have been using the motor for few years and was not running smooth at idle so...
Colleagues,
I have a leakaege in the lower unit , not in the propeller shaft but in the bearing carrier . It looks like the o ring is weared out.. Tried many time to unscrew it , knowing that is left hand thread and even applied heat . Not that mutch, but enough to get it warm.
So the question...
