I came across your post. I have the same pump and motor from my 1975 mercury 85 hp engine. My motor is shot and I need to replace. Any idea what the model number for the motor only ??
Thanks for the update. I have a 1975 850 merc. I have rewired and basically rebuilt the engine. Now have a fuel issue to deal with. 20 gal built in tank. I should of cleaned it out before filling up.
