The HIN requirements in the United States where established in November 1, 1972.

Between 1972 and 1984, the format was ABC 12345 C3 93
ABC = Manufacturer code
12345 = Serial Number
C3 = Date of Certification or Manufacture
93 = Model Year
The HIN you provided does not comply with this format and I suspect it was manufactured prior to November 1972, therefore followed its own numbering format.
To me the number (14TF72 000908) looks like:
14 = Length
TF = ??
72 = Year of Manufacture
000908 = ?? (Serial Number?)
None of this would provide the specs for Capacity or HP. However that can be calculated mathematically. On boats less than 20 feet in length with no capacity plate, use the following rule of thumb to calculate the number of persons (weighing 150 lbs. each, on average) the vessel can carry safely in good weather conditions.
Number of people = vessel length (ft.) x vessel width (ft.) ÷ 15
For example, for a vessel 18 feet long by 6 feet wide, the number of persons is 18 times 6 (or 108) divided by 15, which equals seven 150-lb. persons (or a total person weight of 7 x 150, or 1050 lbs.).
You can calculate the approx. Max HP for any boat with the following calculation:
HP = Max Horse Power
L = Length
W = Width @ Transom
Multiple L x W, then take the Result and use the chart below to determine Max HP for the vessel.
RESULT MAX HP
0 - 35 3
36 - 39 5
40 - 42 7
43 - 45 10
46 - 52 15
If length x width is greater than 52, use this formula: ((L x W) x 2) - 90
Rounded up to the next multiple of 5.
If the transom is less than 20" high OR the motor is tiller steered, use this formula instead:
((L x W) x .8) - 25
Rounded up to the next multiple of 5.
========================================================================
L = 13 foot 6 inches
W = 53 inches
(13.5 x 4.5) / 15 = 4 people Max Capacity or 600lbs
((13.5 x 4.5) x 2) - 90 = 30 HP Max.
