water in sump near shaft packing gland

[sam]

I recently found water in the sump aft of the engine under the packing gland. Of course my first suspicion was the Volvo gland, but turns out that the water was coming from the entry to the water lift muffler. Tightening both hose clamps stopped the leak. I had never checked those clamps before as they were a bit out of the way, but I suggest that its worth the effort. I found that the aft wood partition on the engine compartment was easy to remove / replace and enhanced access. Took the opportunity to grease the Volvo gland using the drinking straw trick. Thanks to all that suggested it..it works well.

70 degrees and sunny here (Galveston Bay, Texas).....going sailing this week!!

My hose clamps also needed tightening last year after I overheated the engine after an impeller failure. I assumed it was because the hose expanded or the clamp was not tightened properly when the boat was built.

Bruce, very interesting. I connected the dots after your comment. I too had a brief high temp event when I sucked small fish into the raw  water thru-hull. Looking into it more, Vetus (the plastic muffler supplier) HIGHLY reccommends a high temp alarm in the exhaust line. Plastic mufflers are subject to issue. The high temp alarm mounts in the wall of the exhaust hose and senses the temp much sooner than the high temp alarm on the Yanmar. I have not installed (yet) just investigatimg. Looks like a $200-300 project.

I think that my exhaust note / sound is a bit louder than it used to be, but I may be hearing things. I am also looking into adding an inline muffler downstream of the waterlift to further quieten the sound. We do a lot of motoring (ICW, etc.). Have 1200+ hrs on the engine now.

Thanks for your comment.
