On my friends Capri 26 he states his handle sticks pushing down to flush, I told him make sure he is pumped out! but than I thought about head lube for him, using mineral oil, I have not seen it. My thought also went to clogged vent loop, boat pretty much sat out all last season and he is a new owner. I will see the boat thursday. Thoughts besides buy Peggys book, which I already have!
