Dear,
Im new on this forum and I looking for help. On my engine Mercury 75 HP four stroke I lose power in gear. Las year on the end before Winter engine works Prfect. In this year from begining I have a problem with engine. I have no power in gear. Max RPM 3200 after some milage of drive. I check spark plugs and found one #3 cyil. not work ( I think so). I buy new spark plugs, new coil, but problem is the same. I check compression all the same. I change spark pluh harness problem the same. No power I can not skiing behind boat. If is not in gear RPM comes to 6500. I think on CDI, Oil press switch, and temerature switch. Do you have some suggestion what I can check?
I hope you understand my english.
Thank you and best regards from Slovenia.
