We got a old glassmate boat, with a 70 evenrude (70673D) outboard. It set 4or5 years out side.. New plugs. 130 compression, replaced some wires and tighten a lot more.. started it runs fine in a 55 gal tank. Question where does the coolant water come out? there are 2 small holes below motor cowling. We think water should come out there but can't find it on Google or several motor forums..any help would be approached. I order a motor Manual from IBOAT!! should be here today..THANK YOU RANSKI
