Hi everyone, I have a 65hp Evinrude triumph 1973 that ive recently bought with a few faults which I working my way through, i'm having an issue with selecting gear, if I make adjustments to the shift cable and throttle lever I can get it into forward or reverse from the controls but not both, I can also engage forward and reverse manually with the cable disconnected ( needs slightly more force for reverse) so far I've replaced the shift cable, set the shift rod to 21-11/32" as recommend and changed the gear oil. It's like the travel on the cable is just that little bit short to engage the gear. Could a worn dog clutch possibly be the cause of this or is there anything more obvious I could check before contacting a professional ? I did notice a few filings on the magnet of the oil drain screw when changing the oil and the original oil did not look great either. I also noticed the bell crank hub where the shift cable connects to is not original and was altered at some stage but I've checked the measurement against a picture of an original one and they seem very similar. Any info or tips would be greatly appreciated. Thanks in advance.
