I had a '88 35 hp that had a cracked tube going from impeller to powerhead. Might check that out!

On my 99 it just slips (falls) out. Hey how does that line break in the first place?

I took the exhuast cover off to get the pump tube off no signs of a crack but there is a hole in the rubber seal that seals the pump tube to the engine.
