You want to look for a Mark 15 or a Mark 20 Lower Unit they are more plentiful. It is a bolt on swap for the KH-7 with all the right parts and correct water inlet holes. Same impeller fits MK 15, MK 20, MK 25, and MK 30. The early KH-7 impeller was only about 1/2" tall. the new style is almost 7/8". New impeller # is 47-20813 Mercury part. or Sierra # 18-3008 good luck.
