I want a small o/b for our little inflatable-- just to taxi between anchored boat and the dock or beach. I'm looking at the Honda BF2D 2hp, mostly because of its light weight. I'm looking for pro & con comments from owners of this motor. Also, the literature says it's an air-cooled motor, but a local Honda guy said he thought this motor has a water pump-- he said something about the pump being for exhaust cooling(?). Anybody know if the Honda 2hp really has a water pump? Thanks.
