    Sea King Outboards

    I was looking to purchase a 15 horsepower Sea King outboard motor for my 14' vee bottom boat. The 9.5 Johnson runs good and is reliable yet doesn't have the punch to really move the boat at a decent speed. She just doesn't want to get on plane real good. So moving up to a bigger horsepower...
