To determine the maximum horsepower capacity for small, flat-bottomed boats, multiply the boat length (ft.) by the transom width (ft.) and compare the resulting value to the following chart:
LENGTH X WIDTH =
MAX HP
35 FT OR LESS
3
36 – 39 FT
5.5
40 – 42 FT
7.5
43 – 45 FT
10
46 – 52 FT
15
EXAMPLE
BOAT LENGTH = 12 FT.
BOAT WIDTH = 4FT.
12 FT. X 4 FT. = 48
MAX HP OF 15
