New to outboards but this forum is a life saver!
I have a 1970 85 hp Johnson (85ESL70B) and I want to put a tell-tale on it. I have seen on here about drilling and tapping into the water jacket around number one cylinder. My question is on the powerhead just past the headgasket on the starboard side there is a flat head screw that looks to me like it is already going into a water jacket. (its number 11 on the exploded view of powerhead group, called Plug,cylinder). Does anyone know if this screw is thread into a water jacket and if it does can I use it for my water line fitting?
Thanks in advance for any advice!
