Re: 1978 mercury 115 replacement trim fill screw
Sorry, I don't have the P/n or s/n of my engine. I guess that would have been good information to write down before I posted my question. As soon as I get home, I can post that info. Part #2 is not the part I'm looking for, the part I'm looking for is the trim reservoir fill screw. My pump has an vertically mounted electric pump motor, two solenoids at the top, a square reservoir under the motor, a vent screw right next to the fill screw, then a manual trim knob, and four hydraulic lines below that. Sorry for the long reply, but thank you so much for your help.
