Wallas was the culprit

I was getting a cup full of water in the bilge under the galley. Tracked it down to the Wallas exaust pipe shipping water in rough weather. I confirmed this by spraying a hose on the side of the boat when back at dock. The flexi exaust had not been installed onto the "L" shape S/S pipe that exits the boat with sealant or a proper clamp, just a mickey mouse hose clamp. I used the proper high temp sealant and a heavy duty clamp on the metal part of the exaust and put the mickey mouse clamp back on just to keep the fire retardent sock in place. Should be problem solved.

Good sleuthing and it sounds like you improved quite a bit on the original installation :thup I guess the leak must have been coming from the exhaust/through-hull joint, thus the gooseneck of hose was being "ignored" by the water.

My Wallas exhaust hose didn't have the sock, but it also ran clear of any other objects. I don't remember if there was sealant on the exhaust to through-hull joint, but there was a higher-quality-than-usual hose clamp (kind of a special looking slightly thinner one with no cutouts in the band).
 
Bridma, I spoke with Doug at Scan Marine when I moved my Wallas stove and added the wind deflector to the exhaust outlet. He told me to be sure to cover the entire back side of the mounting flange on the exhaust outlet with high temp RTV sealant because the L shaped pipe is just spot welded to the mounting flange that attaches to the side of the boat which can allow small amounts of water to enter the boat via the spaces between the welds.

Sunbeam, you might want to consider adding the fabric sock covering to the exhaust pipe if you store anything under your stove. When I moved mine I ran it for about an hour without the sock so I could see everything, check for exhaust gas leaks, etc. I was surprised by how hot that exhaust pipe got. After the stove cooled I installed the sock and ran it for another hour and was surprised again at the huge difference it made. I wouldn't have considered grabbing that hot pipe with my hand without the sock, it was that hot, but with the sock on I could hold it in my hand for quite a while before it got uncomfortably hot.

Thanks for the note on the exhaust sock. I've actually removed my Wallas 95 in favor of separate heating/cooking appliances (and the person who now has it is a Wallas veteran so will probably install the sock), but I appreciate your taking the time to let me know (may come in handy yet if I go with a Wallas heater).

Thanks Mike for the info. The only water I saw coming in was where the flexi exaust pipe fits over the outside of the "L" shape tube. This is the area I fixed. I was wondering about putting high temp sealant around the "L" tube where it exits the boat from the inside. I held off on that until I check again in rough seas.
Cheers,
Martin.
