Just got done installing my 75 merc 2002 2 stoke on my skiff..The thorttle to go forward is SOOO stiff..I know there is alot of talk on this topic,Soo tonight im going to unbolt the cable's from the motor and see if they are stiff that way..I did notice when i put it in neutral and give it gas its not as stiff..So I guess alot has to do with putting it into gear!! What would make that soo stiff? Anything I can Lube?
