I am trying to come up with a better way to flush the motor on my 252, I've never been a fan of those ears, always seems like there isn't enough water going through to me. I've seen kits at Boater's World that allow a modification to the pick up lines going to the water pump. They are advertised as a "winterization conversion kit." After looking at my setup I don't think that particular kit will work, but maybe I could fabricate something of that nature. Any advise or warnings I should take into consideration?
