I have a 1988 85 HP Force and i was just looking at it after i read something on how to install a tatle tale line. For some reason the photo bucket images were not working when i was reading the thread on the how to. i have attached two pictures that i think it might be. Thank you in advance

You'd probably snap off the tiny screws as soon as you look at them
