[C320-list] Cracking thru hull hoses

[Robert Sloat]

Jeff-I have hull 894 and checked my maintenance book after your note.  I noticed a little cracking and hardening of the thru hull to raw water strainer and strainer to engine raw water pump.  They were replaced in 2009 during their  8th season.  They are different sizes.  The one from the thru hull is 3/4” and the one to the water pump is 5/8” I believe, but would recommend checking IDs before getting new ones.

After shutting off the engine I noticed that water left in the line was leaking out of some tiny cracks in the small portion of raw water intake hose connected to the thru-hull.   So, I got a replacement wire reinforced hose.  Taking the old hose off, and bending it a bit, it simple broke wide open.  Glad I noticed this.
