The K16BD is designed for a more budget minded buyer versus the  K16CC.  The primary differences are:

1. The K16BD uses portable fuel tank – fairly substantial savings over the new EPA permanent fuel tanks.
2. The K16CC has a short rear deck and a cooler seat behind console. BD has a long rear deck with a cushion to sit on.
3. The K16BD has smaller switch panel and no bilge pump.
