Hi there my fellow sailors,
a question for ya:
I live in Mexico
and it is very difficult to get hoses, especially marine
hoses. I needed to replace the hose that goes from the stuffing box to the outside outlet, that exits salt cooling water
humes and gasses.
Now, the only hose I could find that was strong enough and still flexible enough can hold up to 150 F or 66º C temperature of the exhaust
gasses and cooling water
. My pretorien is only used for coastal sailing and not long trips. The maximum time the engine
will be used is an hour. Can I do safe coastal sailing with this hose?
I have a volvo penta
in my sailboat of 45 HP. I hardly bring it up more than 2.000 RPM
Also, because of the limited length of the hose that was available, I could not connect it in the way the previous hose was connected, which was in a downwards way from the stuffing box over a length of appx. 3 ft and then directly going upwards for appx. 1,5 ft (50 cms) over a beam and down to the outlet. Now the hose goes inmediately in an upwards direction from the stuffing box to a max of appx. 1,5 foot (50cms) in the end and then over the beam down to the outlet. The outlet of the engine
towards the stuffing box is appx. 1 foot (35 cms) high. The total length of the exhaust hose from the stuffing box is appx. 7 ft. Can this cause a problem of cooling water flowing back into the engine or is the amount of water that will flow back not enough to go up the 1 foot to the engine?
I am unaware if I have a protection valve that avoids water from flowing back into the engine. I have a volvo penta
