Re: 77 115 hp tilt and trim
If its a inside the hull pump, theres 2 screws right on top of the reservoir. One a vent, leave open, one a fill. Tilt the motor all the way up, and fill with 10-30 oil.
Nothing to it..
If you are low and can't get it all the way up, just do a little at a time..crank motor up down a few times to purge the air.
