[C320-list] Yanmar 3GM30F Hose Replacement Project

[danny jensen]

My hull is #972 and I had a situation where I had a leaking hose that
sprayed salt water all over my motor and this caused a large amount of
rust around the high pressure injector. My boat was due for a coolant
change so I ordered new hoses and a thermostat. I also needed to order
some Yanmar Grey spray paint and I got some brush on grey rustoleum
paint from Wal-Mart. It is a good time to change the Thermostat and
paint at the same time as you change the hoses because there are rust
pockets behind the hoses and my fuel tubes were rusty. The hoses and
thermostat were very easy to replace but the rust removal and painting
took the most time. Allocate about 6 hours for this job including
coolant change.

The parts list is below.
