I just got my Wallas stove back from the repair shop at Scan Marine in Seattle. It's fuel pump was shot and it had other problems. I was told it was suffering from blow back from the wind blowing into the exhaust pipe. They sugested that I install a clam shell cover over the exhaust. Let my $500 of pain be a lesson to us all. Cover that exhaust.
Safe boating to all of my Glacier Craft brothers and sisters. See you on the water.
