going to change lower unit oil and was wondering if i need to replace the o rings on the screws--------dont know much about boat motors so any help would be great thanks josh
It is always a good idea to replace them as most water intrusion into the gear case is caused by those rascals. Do not remove the phillips screw. Best of luck. Rick.
also i was looking for an oem manuel for this engine and i found one for a 1969 evinrude 9.5 would this work? i plan on doing alot to this motor so im sure this thread will get much bigger

The MQ was a brand new motor for 1964 and it carried over unchanged (except for decals) for 1965. In 1966 they changed the cowl latch, motor mounts and I believe they also may have changed carb and/or timing in order to get more economy out of cruise operation. The best bet is to get the model year-specific OEM manual.
For nearly everything the newer manual should be fine. If it were me and I were planning on going through the whole motor I would consider the 1969 manual but keep looking for the right 1965 manual.
