The hoses were cracked and appeared that some were leaking. Decided to replace all the hoses on the 1976 200 hp Evinrude. Not the hardest task, but still time consuming since it has 3 carbs and numerous 3 way fittings. Replaced all the zip ties with hose clamps. Still leaks around some of the fittings. Hose was the same size, but I don't believe was marine grade. Had to push quite hard to get the hose in the fittings. Is it the hose or did I tighted things down too much. WHAT AN I MISSING HERE?
